Gas burner for roofing work. Gas-burner. The main tool for weld-on waterproofing is a manual gas burner for roofing.

The past decade has been characterized by the emergence of revolutionary changes in the technology of arranging soft roof coverings. Classic roofing felt has given way to modern built-up materials. The composition of the tools required to perform the roofing works. Bucket of bitumen and brush replaced roof burner.

What kind of equipment is this?

Gas-burner– irreplaceable hand tool to perform work on the installation of soft roof coverings using modern weld-on materials. The flame torch formed by a working burner allows you to create local heating of the surface to perform the following operations on the roof:

drying wet areas of the underlying surface;
heating and melting of the lower bitumen layer of the welded roll material.

In addition to performing work on the roof, the roofing gas burner is used:

for heating various products and materials to the required temperatures;
when soldering metals with light alloy solders;
for burning old paintwork.

Design and principle of operation of the burner

The roofing gas burner includes the following elements:

To operate the burner you will need the following additional equipment:

liquefied gas cylinder;
gas reducer - reduces the gas pressure from the cylinder to the working pressure (0.1 - 0.15 MPa), stabilizes the gas flow in the burner;
flexible hose – connects the burner to the output of the reducer.

The weight of the burner is small, no more than 1 - 1.5 kg. Many models have the ability to switch to standby mode, when during short breaks in operation the gas supply is reduced to a minimum that allows the flame not to go out.

A convenient option that saves gas and eliminates the need to re-ignite the burner after breaks in operation. To ignite the burner, it is usually used external source flame: matches or lighter.

Roof burner models

GGS-1– the simplest and most popular model. Flame length 600 mm. Versatility and low weight determine a wide range of applications.
GG-2– basic model of a gas burner. It has an excellent price-quality ratio. An excellent choice for DIY roof repairers.
GG-2U– the model is similar to GG-2, differs by a shorter main tube. Convenient for working in hard-to-reach places.
GG-2S– the beginning of the professional series. The burner is adapted to operate at strong wind.
GGK-1– has a weighted glass and a trigger gas supply mechanism.
GGS-4-1.0– has 4 glasses, simultaneously covering the entire width of the roll with flame. Significantly speeds up work on large volumes of roofing work.

Application of gas burners

The gas burner is practically an indispensable tool during roofing works using fused materials. A well-chosen high-quality burner allows a team of two people to lay up to 60 rolls of weldable material in one daylight.

When performing work with an open flame Special attention must be given strict adherence to all rules fire safety. So, if the area to be covered exceeds 500 square meters, prerequisite is the presence of fire hoses at the site.

There must be access to the hoses from all four sides of the surface to be covered and the possibility of spilling water at any point of the laid covering.

Stages of work when laying material using a roofing torch

Work on arranging the roof with rolled fused materials is carried out in several stages:

How to make a gas burner with your own hands?

Today, manufacturers offer a huge range of gas burners that can satisfy almost any user. But, there are times when a homemade tool takes its rightful place in a home workshop.

Making a gas burner with your own hands is quite feasible at home. If for one reason or another you cannot buy or make a burner, you can rent/rent it.

What you will need for this:

Gas jet with a nozzle passage diameter of 0.8 mm. The easiest way is to pick one up from a used car carburetor. Home gas stoves are often equipped with a set of additional jets.
Gas line - copper or brass tube 70 - 80 cm long. The diameter and thickness of the walls are selected so that it can be cut from one edge internal thread to secure the nozzle.
Wooden or plastic handle. Wide range of options. It should be beautiful and comfortable.
The glass is the body of the burner and protects the combustion zone. You can pick up a piece of thin-walled metal pipe length 100 - 140 mm, internal diameter 25 - 40 mm. Can be made from sheet metal 0.8 - 1 mm thick. Connect the edges by welding or using rivets. Manufacturing materials: soft iron, copper, brass.
Control valve. Perhaps the most difficult issue is in the design. It should easily shut off the gas and be convenient to use. You can search among the plumbing fittings, or you can pick them up from a used home gas stove.
Gas cylinder, reducer, flexible hose. There is no need to invent anything, just take something ready-made. These elements directly address issues of safe operation.

We assemble in the following sequence:

In the gas line pipe On one side we cut the internal thread and screw in the nozzle.
We attach a glass to the same side of the tube from the outside. We use three spacers from available material.
Drill a hole in the handle, insert the other end of the gas line into it and fix it with glue.
We connect the output of the control valve with the end of the line protruding from the back of the handle.
We connect the input of the control valve to the flexible hose, fix it with a clamp.
Connect the second end of the flexible hose, reducer, gas cylinder.
Let's turn on the gas and wait for now the gas will displace the air in the hose.
Set it on fire, adjust it the required flame length.

When making a burner with your own hands, you must remember that a gas burner is a high-risk tool. Consider every transaction carefully. It is necessary to exclude the possibility of gas leakage during operation homemade burner.

Safety rules when working with gas burners for roofing

Carrying out work on the roof using a gas burner affects several areas of labor protection:

work at height;
work carried out with open fire;
handling of flammable substances.

Use, strictly observing safety precautions, is the basis for preserving human life and health.
Accordingly, the entire range of security measures can be divided into three parts.
Measures to prevent a worker from falling from a height:

the presence of shoes that prevent the worker from slipping off the roof surface;
safety devices to prevent falls from a height;
presence of fencing of the working area, walking walkways, etc.

Measures to protect workers from exposure to elevated temperatures:

availability of special clothing, gloves;
Do not direct the flame towards people or elements of the gas installation;
You must not leave the work area or climb scaffolding with a lit burner in your hands.

Fire safety measures:

ensure availability in work area primary fire extinguishing agents;
work with an open flame can be performed during daylight hours in the period from 8 to 18 hours;
no more than one liquefied gas cylinder can be in the work area at a time;
it is necessary to exclude heating of the gas cylinder;
Avoid overheating and ignition of the deposited material.

Before starting work, it is necessary to inspect the gas equipment and ensure its functionality. Check the tightness of the connections of the cylinder, reducer, hose and burner.

conclusions

Practice shows that to successfully complete any work, two main tasks must be solved:

carefully and comprehensively study the subject of the work to be done;
choose the right tool.

Knowledge gives 50% of success in the upcoming work, and a high-quality, wisely selected tool – 80%. Take action, everything is in your hands!

To carry out repairs and other roofing work that involves melting mastics and laying roofing materials, you will need a special gas burner. The device is primarily used to perform the following tasks:

Heating and drying of roofing materials;

Metal cutting and soldering;

Firing a layer of old paint.

Approximate structure of a gas burner

The gas burner has a fairly simple design. It is a glass made of metal and equipped with a nozzle and a handle, which is attached to the body. Heat-resistant plastic or wood can be used to make the handle. Gas enters the housing passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner glass should have a shape that protects the flame from being blown out by the wind.

There is a valve on the burner body that allows you to adjust the flame length and intensity of the supplied gas. It’s good if the burner has a reducer, which allows you to use gas economically.

Roof burner components

During the assembly process of the device, mechanical processing is practically not used. The burner is assembled from ready-made spare parts. To make it we will need:

A steel valve that can be taken from a cylinder intended for storing liquefied gas.
A plug used for transporting gas cylinders.
Jet from blowtorch with a nozzle diameter of 0.8 mm.
A piece of pipe one meter long with an internal diameter of 10 mm. and steel thickness 2 mm.
Wooden handle.

You can use the handle from a burnt-out soldering iron as a handle.

Step-by-step burner manufacturing process

The process of manufacturing a gas burner begins with the fact that we insert the supply tube, for which we will use a steel pipe, into the handle and secure it with glue. The divider and body must be machined from a brass rod, the diameter of which should be 20 mm. In the finished body, two radial holes are drilled (each diameter is 5 mm) and four holes are drilled in the divider rod (each diameter is 1 mm).

When assembling, it is necessary to press the divider into the body with a slight tension. At the same time, the flange must be installed inside the housing with a gap, that is, the internal diameter of the manufactured housing must be 0.6 mm larger. diameter machined The resulting gap is responsible for braking the gas flow, which is supplied to the drilled holes in the igniter.

Such nozzles are found in purchased models

To do thin hole in our nozzle, you need to take a drill with a diameter of 2 mm. and with its help do blind hole, which is 1.5 mm. doesn't reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely caulked with gentle hammer blows. Then you need to sharpen the end. To do this, take sanding paper and sharpen it until the desired cross-section of the outlet hole is found, that is, until the nozzle can be placed on the tip of the threaded burner tube.

A supply hose made of fabric-rubber material must be attached to the end of the gas supply tube. Secure the hose to the tube with a clamp. We exhibit operating pressure, after which we supply gas. Wait until all the air is forced out of the hose, and only then insert the nozzle into the flame of the gas burner.

Attention! The nozzle is introduced into the flame without a housing or a divider.

Next you need to sand the end. The length of the burner flame should ultimately be 5 cm. We put the body together with the divider onto the external thread of the nozzle. Make sure that the burner produces an even flame with no signs of soot.

To achieve the desired effect, slowly rotate the body on the nozzle thread.

If you have a loose threaded connection, seal it with FUM tape.

Video. How does a roofing gas burner work?

Hello! My name is Viktor Kaploukhoy. I am an engineer by training, graduated Technical University. Hobbies: IT, engineering and technology.

In just two decades, construction technologies have been updated, new building materials and tools have appeared. For example, the old faithful roofing felt has given way to new fused roofing materials, which are better in all respects. No one will argue with this anymore. And accordingly, the bucket with hot bitumen and a brush for coating has gone into oblivion, instead of which builders today use a gas burner for roofing work.

What is a gas burner

This is a hand tool connected to a gas cylinder. It includes:

An injector, inside of which a nozzle with a through hole of small diameter is installed. Through it, gas in the form of a flame is supplied to the place of surfacing or drying.
Cup. This is a device within which flammable gas is mixed with air (oxygen). The glass has many holes through which air is sucked into the flame zone. In addition, this device protects the fire flame from the effects of wind.
A valve that opens the gas supply and regulates its pressure, and accordingly the length of the torch.
The main pipe that separates the torch from the handle that the welder holds.
Handle made of plastic or wood.

Of course, to operate a gas burner, you need a hose connected to the cylinder and a reducer that reduces the gas pressure in the line. The gas pressure at the burner outlet is 0.1-0.15 MPa. A propane gas burner for roofing weighs a little, in the range of 1.0-1.5 kg. So it is convenient and easy to work with it.

How to make a burner with your own hands

In principle, the design of a propane gas burner is simple. The main thing is to assemble the nozzle and glass. The remaining elements and parts are ready-made units and parts that are sold in any hardware store. Therefore, it will not be difficult to make it yourself.

So, what is required to assemble a burner with your own hands?

Gas burner assembly

First of all you need at one end copper tube cut the internal thread using a tap of the appropriate diameter. Copper is not a very hard metal, so it will not be difficult to carry out this operation with your own hands. It will also be easy to screw in the jet.

With a glass everything is more complicated. To do this, you will have to cut one side of the pipe into several longitudinal petals (6-8 pieces), and then bend them towards the center. You will get a cone, but there is no need to bring the petals to the end; you need to leave room for the main tube, onto which the glass is placed. After which the petals are pressed against the tube, where they are sealed. There are slots between the petals that will serve as air supply inside the nozzle. The length of the petals is approximately one third of the entire length of the glass.

Important! The jet should be located at a distance equal to the length of the petals. That is, a flame of propane and oxygen should form at the level of the slots.

The gas burner for roofing work, or rather, its front part in the form of a nozzle is ready. All that remains is to assemble the back part. To do this, you will need two M25 bends made from a pipe with a diameter of 25 mm with threaded threads. In a one-way bend, in a place where the thread is not cut, a cone is formed into which the rear part of the main tube is inserted. This can be done by heating the squeegee with an oxygen torch and tapping it on all sides.

A gas control valve is screwed into it. The second connection, it is double-sided, is screwed into the valve on the other side. Be sure to wrap it on a sealing material. For example, on fum tape. An adapter from a threaded connection to a hose connection is screwed onto the rear end of the second bend. There is no point in making it yourself, because it is sold in any hardware store and is very cheap.

Now all that remains is to make the handle and install it on the prepared device. There are a huge number of options for handles. The main thing here is to hold the entire homemade device comfortably. For example, it can be cut from wooden board 5 mm thick, you can buy an ax handle and adjust it to the size and shape. It is better to attach the handle to the brackets, because this is the strongest section in the entire structure. Optimally, this is a rear drive, because the control valve should be located slightly in front for ease of use.

Attach a piece of wood to metal tube it can be done in different ways.

Make a recess along the entire width to fit the diameter of the pipe of the squeegee, place the squeegee in it and secure it with two clamps made of metal tape.
Install the squeegee on the side of the handle and also secure with clamps.

So, you have made a gas burner for roofing work yourself, you can connect it to a gas cylinder and carry out testing. To do this, the hose is connected to the cylinder through a reducer, where it is secured with a clamp. Its second end is threaded into the adapter, where it is also secured with a clamp.

The cylinder opens, the supply of propane through the gas reducer opens. And the last thing to open is the control valve on the injector. Gas should flow through the nozzle with a characteristic sound. You must wait until the air inside the device is completely released. After which the gas flow is ignited. The valve near the handle regulates the length and power of the torch.

Attention! A homemade gas burner for roofing work is a high-risk device. Therefore, all operations performed must be approached with special care. This is especially true for the connections of all elements with each other. Complete tightness must be maintained.

Fire safety measures

Regardless of whether a factory gas burner is used or a homemade one, fire safety requirements must be strictly observed.

Keep a fire extinguisher on the roof when performing roofing work.
All work is carried out only during daylight hours.
When laying a soft roof using a gas burner, only one can be brought onto the roof. propane tank.
It must be avoided from heating up.
Do not overheat or expose the material being laid to fire. roofing material.

Like these ones easy conditions, which guarantee the safety of construction operations involving roofing with fused materials. They are simple and easy to do, so there shouldn't be any problems.

Roof microburner– this is a movable structure with comfortable handles for carrying. The Sympathy contains a small weight, up to 1.5 kilograms, and is equipped with a handle made from a log or plastic that is comfortable for use, up to 1 m long.

In the gas property, the only thing used is hydrocarbon. Someone acts in the shell using a gas hose. Its supply and length of fire are regulated with the support of a special valve in the burner. In order to save exhaust gas, roofing games are equipped with a gearbox, which controls fuel consumption.

Absolutely all gas burner systems take into account the concept of atmospheric suction. This is an inevitable role, but it is also necessary to accept auxiliary ones, which provide the service in the most convenient way.

In the main priority is the possibility of coordinating workers' regimes. For example, if there is a stop in the service, the order of hope is introduced and fuel is saved. Each gas microburner lights up with ordinary matches or a lighter.

Less known, but also used for roofing work, are games that operate in diesel fuel.

What kind of equipment is this?

The structure of the burner includes an owner with gas supply regulators, from what it turns out Railway with mixer at the end. The microburner is connected with a rubber sleeve to the hydrocarbon-slide gas cylinder using a pressure regulator.

Basically, tamed gas games are used for the purpose of heating the plane and fusing different substances. Gas games come in two types: forced and non-forced atmosphere.

These types of burners have the following characteristic industrial properties:

Atmosphere supply in a gas burner with forced supply performed in the following way, air is supplied with the support of a propeller or compressor. The advantage of this type of game is the likelihood of a clear torch option. The downside is the difficulty of installing the device.
In burners that do not have a forced supply of atmosphere, air is supplied freely through a hole in the diffuser due to the number of gas supplies. The simple structure makes it possible to do it yourself. The disadvantages include the inadmissibility of a clear torch option.
The gas microburner is started by igniting a gas stream, which is obtained from the diffuser; in some modifications, automatic ignition is taken into account.

Design and principle of operation of the burner

The design of the gas game consists of the following elements:

A metal cup with convex holes along the sides.
A nozzle for the purpose of spraying gas.
Plastic or wooden owner.
Rubber sleeve with the purpose of gas cart to the body of the game.
Valve for regulating the supplied gas and the length of the fire.

Due to the modification, the game has the following differences:

Fuel supply is forced and non-injector.
Power and gas consumption.
The amount of fire supplied. Accept single-flame and multi-flame.
The method of using the device is easy and electromechanized.

The length of the game due to its installation is from 0.8 to 1 meter and the weight is approximately 1.5 kg. In addition, due to the modification, gas games have every chance of being equipped different modes saving fuel.

Roof burner models

For work related to laying the roof, a specified type of device with the following modifications is used:

GG-2 propane micro-burner for the purpose of preparing and performing waterproofing work. Excellent for small-scale roofing work. Recommended for use by young professionals. Mostly low price.
GG-2U The similarity of the previous modification is distinguished by the curly gas route. It is mainly used in inaccessible areas near the roof.
GG-2S It seems to be a high-quality burner, and in addition it operates in propane. Contains 2 valves for the purpose of clearly regulating the order of operation and the likelihood of operation in very windy weather.
GS1-1.7 contains small mass, and the volume appears to be multi-purpose. It is used for the purpose of drying and fusing substances into the roof. Makes it possible to heat the plane up to four hundred degrees.
GK-1 The air-propane microburner is armed with a depressing cup and a gas supply lever. It is used for the purpose of removing color by burning in wood surfaces and waterproofing roofs.
GS1-1.0 contains a simple mass and small volumes, which makes it possible to use it for waterproofing roofs with a huge slope.
GGS1-0.5 Mainly used for the purpose of small repairs to the roof and for economical use of gas in a project.
GGS4-1.0 contains 4 cups of fire supply. It seems economical and allows 1 person to process a large amount of shelter in a short period of time.
GV-3 used primarily for the purpose of heating metals for welding or soldering.
GV-111R used for the purpose of fusing narrow-roll bituminous substances into the roof. In addition, it is used for the purpose of burning the previous color in different surfaces.
GV-50, GV-900 comfortable and easy to use, distinguished by the length of the torch.
GV-500 I use it for the purpose of fusing bituminous substances. Makes it possible to warm up the heated surface up to THREE HUNDRED degrees.
GSV-850 contains an injection type of fuel supply. The microburner is equipped with a valve for a clear gas supply option and a lever for adjusting the length of the torch.

It is necessary to direct interest in such characteristics, as well as:

Fuel requirement.
Flame torch size.
Heat performance.
Weight and length.

Application of gas burners

For the purpose of repair work and the adaptation of roofing with bituminous substances, a gas burner is preferably used. Due to 8 hours of labor time, approximately 600 square meters of welding material can be placed next to a high-quality burner.

Carrying out work in accordance with the adaptation and repair work of the shelter different types with the use of gas, the installation must be laid in accordance with absolutely all fire protection laws.

For work on laying different areas of the roof using gas, accept established limits such as:

You can only lay no more than 500 square meters at a time.
When laying more than 500 m, the presence of fire hoses with water is necessary.
Has access to fire hydrants and is required to appear at four edges of the mulched roof.
Water supply using a fire hose must be supplied to each point of the laid plane.

Stages of work when laying material using a roofing torch

The procedure for laying bituminous or so-called soft surfaced substances using a gas game consists of the following steps:

Cleaning the roof surface from debris.
Unwinding the rolls in the plane of the roof with an overlap of at least 10 cm for marking purposes. Subsequently, the rolls must be wound and numbered.
Priming the plane with prime in order to remove microcracks, chips and dust binding.
Having marked the plane and primed it, the rolls are unwound over time and heated with a gas burner in order to fuse it into a plane.
During the final period of laying movement, it is necessary to heat the seams of the deposited substance with a torch.

After fusing the substances, in order to prevent wrinkles, the covered plane must be rolled out with a roller.

How to make a gas burner with your own hands?

A gas burner can be made personally in domestic circumstances; for this purpose, the following components will be needed:

Rectifier with pressure reducer to regulate gas supply. It can be taken from an oxygen cylinder.
A stopper that is used for transporting gas cylinders.
Liquid fuel nozzle with a nozzle diameter of 0.8 millimeters. It can be taken from a gasoline blowtorch.
A piece of iron route, a tube version, with a length of only one unit with a diameter of 10 millimeters and a wall width of 2 millimeters.
Handle made of slightly heat-permeable substance. Mostly from a log.
Shell and gas divider game (cup). They can be turned from a brass rod with a diameter of 20 millimeters.

The further installation procedure for the gas game consists of the following steps:

The road is inserted into the made handle and secured with glue.
In the turned body it is necessary to drill 2 radial holes with a diameter of 5 millimeters. In addition, in the housing it is necessary to drill 4 holes with a diameter of 1 millimeter in the divider rod.
The next step in the game production is simply sketching the cutting rod into the shell. The completed shell must be fixed into the railway.
In the routes with the inserted housing, it is necessary to cut the thread with a tap and screw in the nozzle.
At a different route end, a gas-air hose is connected and secured with a clamp.

After installing the gas game, you need to unscrew a certain oxygen rectifier and wait until the blue fuel squeezes out the air space in the sleeve. Then use matches to burn the flow of gas from the body (glass).

Safety rules when working with gas burners for roofing

When operating a gas burner, strict compliance with the security laws is necessary:

Before starting the activity with the device, it is necessary to carry out an inspection of the game into the object of automatic defects and loss. ant. gas income. Micro burner for roofing work
The arson game cannot be played by standing in front of the glass nozzle.
Work must be carried out using canvas gloves, overalls and shoes.
When working with a gas burner, you must be careful not to overheat the raw material being welded. Thus (as well as overheating can cause destruction of the substance.
At the workplace where the microburner is used, there is no need for third-party objects, especially flammable ones.
When working with a gas burner, fire extinguishing resources must be available near the laying area.
The repairman operating with the device is in no way obliged to move with the burnt burner anywhere other than the mulched surface.

The principles of safety during operations with a gas burner must always be observed and indisputably oh, thus it is also a guarantee of the unity of the functioning Person and the people around him.

A gas microburner seems to be a necessary assistant for laying the roof with gentle substances. Such a device, as well as a gas microburner, is widely used in construction and correctional work.

As a rule, gas flames are used for the purpose of fusing roofing materials, removing color from various surfaces, welding and soldering various metals. Game of taking various types systems for the purpose of different types of work.

It should be immediately noted that it is much easier and more harmless to purchase a finished burner than to make it yourself. However, if one accepts the belief in own strength and passion is always accomplished with one’s own hands, in which case it is permissible to try.

Gas micro burner- this is a difficult apparatus and for the purpose of this, in order to produce it, some skills will be needed, and the detailed implementation of a large number of laws. However, it is always better to preserve the activity element for the purpose of specialists. This primarily concerns the organization of supply and containers in order to preserve gas.

To produce a torch, a metal base and a gas divider are used. Attach them to the handle from a heat-resistant log.

The hose for supplying gas is drawn from a gas welding organization or personally ground from brass.

Despite the fact that in appearance a roofing micro-burner selected with its own hands differs quite significantly from its shop counterparts, it will manage its main functions.

But next to the service, it is necessary to especially carefully concentrate interest in the smallest gas leaks or other problems. And even on a number of minor issues, the service must be interrupted immediately. Roofing information works in low fuel conditions.

They are especially important for operating near extreme temperatures; in this case they are equipped with integrated fuel heating. They are fully automated and ready to work with gasoline of different properties.

Diesel roofing games are equipped with a high-pressure blower concept, which guarantees stable and reliable ignition and reduces the formation of soot.

Low-fuel burners stand out from their gas counterparts. In a diesel engine, the fuel enters the chamber under great pressure, which leads to water splashing. And the previously sprayed fine particles are ignited at the exit from the nozzle, forming a fire.

In conjunction with this, the microburner is connected to a compressor and a container with gasoline next to the support of oil-gasoline-resistant hoses.

In a home workshop or garage, there is often a need to use a high-temperature burner. Its application is widest - from soldering work before roof repair. Not to mention the need to heat up the metal part for processing.

When doing metalworking work on metal, a gas torch can be used to heat the workpiece for the purpose of subsequent hardening. If you are engaged in electric welding, when working with some metals it is necessary to warm up the area of the future weld.

Tool stores sell a variety of tools for safe work with fire. A propane burner can be of any size and any configuration. The size of a ballpoint pen for jewelry soldering:

Or a multi-nozzle ramp for heating bitumen on the roof:

The advantage of industrial options is the safety certificate. However, there is nothing in the design that cannot be repeated at home. Since any product in the store costs a lot of money, we will tell you how to make a burner with your own hands.

Important! Homemade devices for working with fire carry a potential danger. Therefore, a propane torch manufactured without technical expertise is operated at your own peril and risk.

How to make a burner yourself

Let's take a closer look at the nuances that you should pay attention to when making a burner.

First of all, it is necessary to use refractory metals. A properly configured burner can produce up to 1000 ° C, so the nozzle must match the flame temperature;
It is important to choose a reliable working crane. If something goes wrong, the gas supply is first cut off and the danger is eliminated. If the tap leaks, you will not be able to quickly extinguish the flame;
The connection to the gas source (a bottle with a valve or a 5 liter propane bottle with a reducer) must be reliable. It is during operation of poor quality shut-off valves most accidents occur.

Let's consider a typical diagram and principle of operation of an injection burner:

Gas is supplied under pressure through the hose (1). Typically propane. The pressure is formed due to the evaporation of liquefied gas in the cylinder, and it is sufficient to organize a stable and directed flame. A reducer is not required, the amount of gas is regulated by the operating valve (2).

The shut-off valve is located on the cylinder valve. Its function is only to open/close the fuel supply; other adjustments are made using a working tap.

The gas supply tube (3) leads the jet into the nozzle and ends with a nipple (6), which sets the direction of the flame. The nipple with the tube, in turn, is located in the so-called insert (5). It organizes the mixing of gas with atmospheric air.

The insert with a tube and nipple is fixed in the nozzle with a screw. As a rule, the burner is dismountable for cleaning and maintenance of the nipple.

The formed air-gas mixture is directed to the nozzle of the nozzle (8), where the mixture is additionally saturated with oxygen from the air. For combustion stability, ventilation holes (7) are provided.

The burner is made by hand according to the drawing.

Dimensions are designed to work with cylinders up to 5 liters.

We will tell you about the structure of the liner separately; the dimensions are shown in the drawing:

The outer diameter of the liner tube (1) should be half a millimeter smaller than the inner diameter of the nozzle. A washer (2) with holes for air supply is welded inside. The sleeve (3) is designed to fix the tube with the nipple.

The peculiarity of the design is that by moving the tab inside the nozzle, you can regulate the air leak through the ventilation holes. This allows you to regulate the flame temperature over a wide range.

The attachment can be made from steel pipe, but it would be better to turn it from a steel blank on a lathe. The shape of the nozzle should be somewhat narrowed at the outlet, then the flame will be forced and the temperature in the combustion zone will be higher. Alloy steel grade 45 is used.

There are two ways to make an insert: You can assemble it from two tubes and a steel washer with holes. The structure is soldered with refractory solder, with abundant fluxing. Or you can grind it entirely from a steel blank. The second option is preferable.

The supply tube is copper or brass. On the side of the hose connection, a flange is made (concentric grooves can be made for better fixation). A suitable nipple is screwed into the working end. You can take it from a primus stove, or a gas burner from a household stove.

Important! When using a nipple from kitchen stove Remember that the kit comes with different nozzles. For natural or liquefied gas.

The second option will suit us. When the burner is ready with your own hands, it is necessary to carry out initial debugging.

The burner is set to use the gas that will subsequently be used. The insert is lightly secured with a screw so that the ventilation holes are blocked by half.

By slightly opening the operating valve and moving the insert, we achieve an even, powerful flame. Then we finally fix it in the nozzle.

If you did everything correctly, the temperature at the outlet of the nozzle will reach 1100° C.

Let's move from theory to practice. How to make a gas burner using available materials:

The nozzle is made from a classic car pump design. Such items often lie idle in the garage.
The steel used is excellent and the size is suitable for a gas burner.

We cut a “rose” in the back part, bringing the ends to the center. A feed tube will be inserted into this bundle.

The part came from construction pistol for polyurethane foam.
This is a device for reusable use, so the steel is strong and coated with refractory chromium.

The thickness of the tube is almost 1 millimeter, which is quite enough for rigidity.

At the end of the gun tube there is a nozzle with a ball valve to form foam. The ball is knocked out with a thin awl or gypsy needle. The resulting hole is sufficient to supply gas to the nozzle. The tube with the nozzle is connected using semi-automatic welding.

To connect the structure to the working faucet, conventional plumbing fittings with threads were used. It's simple water pipe, no special steel is needed here. The part of the burner where the tap is located does not heat up to critical temperatures. I had to buy a ball gas valve;
The holder is literally made from scrap metal. Handle from a motorcycle footrest. Having lightly processed with a grinder, we get optimal shape. The clamp for attaching to the burner pipe is from the handlebars of the same motorcycle.

Finally the holder fits on a motorcycle handle. The thermal insulation is good, and the burner fits snugly in the hand.

It took one weekend to make and 100-120 rubles to buy a tap and a fitting for connecting to a hose.

As a bonus, look at the drawing of the tested miniature device:

A gas burner for soldering is made from a needle from a dropper. Connects to a lighter refill bottle.

Conclusion! A homemade gas burner is a reality. Just be careful when operating!

Simple and effective method make a gas burner with your own hands - video

When carrying out roof installation and repair work, situations arise when heating or drying of the material is necessary - for example, when laying a layer of waterproofing or constructing a soft roof, when it is necessary to heat up the bitumen-based mastic. For these and many other purposes, a portable roofing gas burner is used.

Using this device, you can perform several types of operations:

drying surfaces;

cutting or soldering of metal elements;

burning the old layer of paint;

other work that requires heating to high temperatures.

Design and principle of operation of the burner

The roof burner is a metal-based glass equipped with a nozzle and a plastic or wooden handle attached to the body.

The design of the gas burner bowl is designed in such a way that the flame is protected from being blown out by the wind.

Gas enters the housing through a special gas hose. Propane supplied under pressure is mainly used. The burner has a valve to regulate the amount of gas supplied. In addition, it is also possible to adjust the flame length.

In order to save gas consumption, roof burners have a special gearbox that controls fuel consumption.

Absolutely all burner models are equipped with an atmospheric air suction system.

To start the burner, use regular matches or a lighter.

Gas burners also provide a device for regulating operating modes. For example, most models have a standby mode, the purpose of which is to prevent wasted fuel consumption during breaks in work.

Since roofing burners heat up to very high temperatures during operation, only heavy-duty materials are used for their production.

The length of the handle for holding the burner should be no more than a meter. The device itself is very light: its weight ranges from 1-1.5 kilograms.

To prevent burns, the burner handles are equipped with a holder made of very durable wood or heat-resistant plastic.

It should be noted that liquid fuel burners that run on fuel oil or diesel fuel can also be used for roofing work.

Stages of work when laying material using a roofing torch

If roofing felt is used as a waterproofing material, you cannot do without a gas burner. It is also necessary for covering the roof with modern built-up types of materials.

The entire process of working with the device can be divided into several stages.

First you need to prepare the base for further laying of the material. For this purpose, it should be cleared of debris. If necessary, the surface must also be leveled using a concrete screed.

After this, the rolled material is rolled out over the entire surface so that adjacent sheets form an overlap with a width of 85 to 90 mm.

Having completed the leveling and markings, the rolls must be rolled up again and strengthened at the base of the roof using a torch. Heating the lower part of the roll and the base of the roof using a burner flame, the material is slowly rolled out, pressing it to the base.

To avoid the formation of wrinkles and air bubbles, you need to run a hand roller along the attached canvas. At the final stage of the work, a roofing gas burner is used to heat the seams of the overlapping material. After this, the seams should be rolled again using a hand roller.

When operating gas burners, you need to know several important points:

The use of this device is possible at temperatures not lower than minus 15 degrees;

if work is carried out at a lower temperature, then you can use a liquid fuel burner;

when using a gas burner to lay roofs with high quality characteristics per day you can lay from 500 to 600 m of roofing material;

since the work is carried out under open air, the gas burner must provide a stable flame supply and reliably protect it from being blown out by the wind.

Roof burner models

Burners are used to carry out roofing work. different models.

GG-2– name of the propane roof burner model. The most suitable sample for self-taught craftsmen who carry out repairs with their own hands. Despite its high quality, it has a fairly reasonable price.

GG-2U has similar characteristics. Distinctive feature This model is a shortened version of the gas supply tube. It is ideal for carrying out work in hard-to-reach parts of the roof, as well as for gluing abutments and joints.

GG-2S belongs to a series of professional equipment. This model runs on propane. Its main advantage is that the device can be operated even in strong winds. The device consists of two valves and two housings, and this makes it possible to regulate operating modes with great accuracy.

GGS1-1.7– low weight, size and high degree of performance make this model almost universal. It is used to dry the roof and fuse soft roofing materials onto it. It is also successfully used in waterproofing and some other types of work that require a high-intensity flame to bring the surface temperature to 400 degrees.

The burner can be used to carry out work on horizontal sections of the roof and on junctions.

GGK-1– propane-air model. Its difference is a heavier and very durable glass.

This model is suitable for burning old paint, wooden surfaces, for carrying out waterproofing work. Gas is supplied using a lever.

GGS1-1.0 used for small works of small volumes, arrangement of junctions. Suitable for use on roofs with large slope angles. Also suitable for laying waterproofing.

GGS1-0.5 used for minor repair work on the roof. It features economical fuel consumption.

Model GGS4-1.0 is equipped with four sockets, which allow simultaneous heating of the roofing material over the entire width and non-stop rolling of the roll.

Thanks to the presence of special hooks on the edges of the device, heating and rolling out the roofing material can be carried out by one person. Using this model, you can significantly increase the productivity of work performed and reduce fuel consumption.

GV-3– a propane torch designed for heating metals, welding them, as well as manual soldering. The diameter of the glass is 50 mm.

GV-111R used for melting rolled bitumen materials, burning a layer of old paint.

GV-550, GV-900– very easy to use samples. They differ from one another in the maximum flame length. The second model makes it possible to work while standing, in full height, since the length of its torch reaches 900 mm. The first model (GV-550) is more suitable for carrying out work at roof junction points.

The GV model is suitable for heating non-ferrous and ferrous metals, melting rolled bitumen materials when carrying out waterproofing and roofing work, as well as a number of other works that require the use of exclusively propane flame.

GV 500 used for welding work during the laying of roofing materials. It can be used to melt bituminous materials. This model can heat the processed material up to 300 degrees.

GV-850– a propane burner equipped with a special valve that makes it possible to precisely regulate the amount of technical gas supplied from the cylinder. The model also has a lever with which the welder controls the length of the flame. This type The gas burner does not operate on pure propane, but on a mixture, part of which is technical oxygen.

Safety rules when working with gas burners for roofing

When operating gas burners, safety rules must be strictly observed.

To carry out roofing work, you need to change into special clothing and shoes with non-slip soles. You will also need some additional accessories: walking bridges, belt, etc.

Before starting work, a thorough visual inspection to ensure that gas burners, cylinders, and connecting hoses are in full working order.

During operation of the gas burner, only one gas cylinder may be present at the workplace. During work, you must carefully monitor the tightness of the connection of cylinders and reducers with hoses.

Do not stand in front of the nozzle while lighting the burner. The direction of the burner flame must be such that it does not affect nearby people, the gas cylinder and connecting hoses.

When working with deposited materials, care must be taken to ensure that they do not overheat or ignite. Heating the material with of this device, we must ensure that it melts only Bottom part canvases. The entire thickness of the material must not be allowed to soften.

The burner should not be ignited by accidentally igniting objects. For this purpose, you can only use matches or a lighter.

When operating a propane burner model, the valve does not open a full turn, but halfway. After waiting a few seconds, the mixture can be ignited, and then proceed to adjust the flame length.

A worker with a lit burner in his hands has no right to go beyond the boundaries of the workplace or climb scaffolding.

The gas burner is extinguished in two stages:

shut off the gas supply;

lower the locking lever.

If there is a short break during operation, the burner must be extinguished. If a longer break is planned, the gas supply to the cylinder must be stopped.

If the input channels of the mouthpieces are clogged, the device cannot be used, as backlashes and pops may occur.

If, however, a backfire occurs or the burner overheats, you must immediately stop working and turn off the gas to the cylinder. The device itself should be cooled by immersing it in a container of water.

CONCLUSIONS

A gas burner is a device that is necessary for certain types of roofing work.

At its core, a gas burner is a metal glass with a nozzle and a handle.

There are many different models of roof burners. The choice is made in accordance with the type of work performed.

When using the burner, you can adjust the amount of gas supplied, flame length and fuel consumption.

When working with a gas burner, you must strictly follow the instructions and observe safety rules.

How the process of fusing roofing material using a gas burner is carried out can be seen in the video.

In the process of roofing work, it is often necessary to use a gas burner. This equipment is used for quickly drying non-flammable surfaces, burning out old paint, heating bituminous materials, etc. Different types of burners are used in construction. For example, a propane roofing burner is often used, and burners running on diesel fuel are often used. Let's take a closer look at the features of this equipment.

A roof burner is a device that generates a flame due to the combustion of a certain type of fuel. Burners are used mainly for heating bitumen components, but can also be used for other purposes. For example, for burning an old layer of paint or for quickly drying a wet surface.

Let's take a closer look at how a roofing burner works, and also get acquainted with the basic principles of working with this equipment.

Types of burners

Today it is possible to purchase burners of different types; the main difference between different models is the type of fuel used.

Gas

The most commonly used gas torch is for roofing work. This equipment is a system that includes two elements - a fuel tank and a torch. The elements are connected to each other by a hose. The advantages of this design include:

High level of mobility;
No need to monitor the gas supply level;

Regulators that allow you to control the flame pressure are located directly on the torch.

Advice! In gas burners different manufacturers There may be slight differences in the design of the torches, as well as in the volume of gas cylinders. However, the operating principle is the same for all models.

The gas roof burner has gained wide popularity, first of all, due to the low cost of fuel. However, as when working with any other gas equipment, when using burners you will need to comply with fairly stringent safety requirements.

Propane

A roof burner operating on propane is essentially a gas burner, and structurally it differs little from it. However, this type of burner is dedicated to separate group. The most important difference between propane torches is the ability to use standard gas cylinders, which are used when performing conventional gas welding work.

In addition, propane is safer than natural gas, and propane burners produce a more powerful flame and a higher temperature.

Advice! It is necessary to purchase gas, including propane burners, only from trusted trading companies that guarantee the quality of their products. Working with homemade burners is very dangerous!

Diesel

The diesel roof burner belongs to the liquid fuel class, so its design is different. Inside the torch of such a burner there is a nozzle into which fuel and air are supplied. After ignition, the created mixture forms a flame of a sufficiently high temperature.

Diesel burners are no less mobile and efficient than gas burners. Plus they are safer. Fuel for diesel burners is more expensive than gas, however, since it is consumed economically, it general expenses when working with gas and diesel burners, they are almost equal.

However diesel burners They are used somewhat less frequently than gas ones; even diesel models are not so common on sale.

Safety regulations

When planning to work with gas burners, you should first familiarize yourself with the safety rules:

When working with any type of burner, it is necessary to use special clothing: thick trousers, shoes with non-slip soles, and protective gloves. To work on the roof, it will be necessary to use other devices - a mounting belt for comfortable carrying of tools, walking bridges, etc.
Before starting work, it is necessary to carry out an external inspection of the equipment - burners, gas cylinders, hoses. If defects are identified, it is necessary to refuse to carry out work until the malfunction is eliminated.

When working with a gas burner, it is allowed to keep only one (working) gas cylinder at the workplace. Additional cylinders will need to be lifted to the job site as needed. Empty cylinders are immediately removed from the site.
During operation, it is necessary to constantly ensure that the connections between the hoses and the burner and the cylinder are airtight.
When lighting the burner, make sure that the flame is directed away from people, the gas cylinder and connecting hoses.

When lighting a propane burner, open the valve half a turn. After the flame ignites, you will need to adjust its length.
It is not allowed to leave the work site while holding a lit torch in your hands. It is strictly forbidden to climb the scaffolding with a burning torch in your hands.
In order to extinguish a gas burner, you must first turn off the gas supply and only then lower the flame lock lever.
Even during a short break in operation, the burner must be extinguished.

Stages of working with a roof burner

When laying fused rolled materials on the roof, it is impossible to do without using a roofing torch. The installation work takes place in several stages:

First you need to prepare the base well. The roof surface is thoroughly cleaned, and if necessary, the base is leveled by screeding.
Then sheets of material are rolled out over the roof, positioning them so that they overlap with a width of 9 cm.

After making sure that the sheets of material are lying correctly, the material must be rolled up again. The extreme part of the material is fixed at the edge of the roof.
Then they begin to warm up the lower part of the roll, gradually unrolling the roll and rolling it with a heavy hand roller.

When laying rolled material, do not allow overheating. It is important to ensure that only the lower part of the roll is heated, and all layers of material should not be allowed to soften.
Modern deposited materials have a protective film on the bottom. During storage of the material in rolls, this film protects the layers from sticking together. When laying, pay attention to when on the surface of the material protective film will burn out completely. At this moment, the heating of this section is completed, since bitumen layer reached the optimal temperature.
After installation is completed, it is recommended to additionally heat the joints of the material and roll them again with a roller.
Working with gas burners is allowed at temperatures down to minus 15 degrees. If it is necessary to work in frosty conditions, then liquid fuel burners running on diesel fuel should be used.

So, roofing burners are devices that are necessary for carrying out a whole range of roofing work. Most often, gas burners operating on natural gas or propane, but with low temperatures they are replaced by diesel burners.

Gas equipment for heating individual sections of structures and various materials widely used in manufacturing and construction industry. Special operations are performed in relation to structures. Here, elastic materials are usually used, which must provide sufficient insulating function. Accordingly, the roofing burner allows the material to melt and thus form joining units.

Device and design

The basis of the tool is a handle, a gas supply tube and a metal head in the form of a glass. The working gas is supplied through a hose connected directly to the connector in the handle. After pressing the handle handle, the valve will open and the gas mixture will flow into the glass through the tube. The fuel supply can be regulated by a reducer for the roof burner, on which a special valve is located. As a rule, glasses are cylindrical in shape. This makes it possible to use heating modes more flexibly. In particular, modern burners make it possible to provide intensive heating, drying and melting of materials at different temperatures. When choosing a model based on its design, it is important to consider how the instrument will be supplied with oxygen. This can be either pumping from the atmosphere or taking air from a special cylinder. The choice of one concept or another is determined by the operating conditions of the device.

Main characteristics

Evaluate opportunities of this instrument follows two parameters - the diameter of the glass and the length of the feed head. The width of the flame that the device can form depends on the first criterion. Accordingly, an abundant flame will bring the work area to the desired state in a shorter period. On average, this figure varies from 50 to 80 mm. As for the length of the device, it will determine the ease of use of the burner in specific conditions. Yes, for cosmetic repairs roof coverings, a roofing burner about 50 cm long is quite suitable. This option will effectively cope with local melting or heating without causing unnecessary hassle in handling the structure. But in large-scale work on laying roll waterproofing, for example, it is desirable to use models that direct active energy over large areas. In this context, we can talk about models with a length from 80 to 100 cm.

Varieties

By and large, all fundamental differences are determined by the type of fuel source. Mostly such burners operate on gas mixtures. For example, propane devices that have a balanced ratio of price, safety and performance are popular today. In some respects, methane is similar to propane, but this option is more suitable for professional use. An alternative general group gas models are liquid fuel appliances. In particular, roofing can cope with the same tasks. Another thing is that in regular use this option will be less economical, but convenient.

Nuances of operation

The quality of the operation is influenced not so much by the choice of burner and handling skills as by the ability to correctly use the accompanying equipment. So, to work with roofing coverings you will need cutters, a hand roller and, possibly, sealants. Before heating, the working strip should be placed so that the rest of the coating does not have air bubbles, folds or various distortions. A manual roller is used specifically to eliminate possible defects. Then you can start heating. As the temperature increases, the roof torch is smoothly aimed at the target area. Then the melt should be carried out to the required state of the material. The process ends with the function of the same roller, which, depending on the requirements for the result of the process, exerts one or another pressure on the canvas ready for bundling.

Reviews about manufacturers

The domestic market offers models of burners of various types, both domestic and foreign. In the Russian segment, we can highlight products from the Donmet and Kalibr companies, which, according to experienced craftsmen, is distinguished by quality and safety in use. This is generally an inexpensive roofing torch that can be used to perform basic roof repairs with ease. More technologically advanced, productive and reliable devices are produced under the Rothenberger and Poap brands. These are not just profitable, from the point of view operational properties, devices, but also universal assistants in other works. As users note, some burners from these brands can be used with a wide range of gas or liquid fuels. In addition, the owners point out ample opportunities control of the power of the devices, which allows the technology to be used when working with structures that require heating power.

How much do the burners cost?

If we're talking about about performing simple work, then you should contact the segment up to 1000 rubles. Actually, already within 700-800 rubles. you can purchase a decent domestic version of the burner. Another thing is that it may not last long and will only cope with small tasks. In the middle segment there is a more functional and productive roofing burner, the price of which can vary from 1 to 2 thousand rubles. These are models from major manufacturers that are capable of implementing almost the entire range of roofing tasks that are targeted for this type of tool.

How to make your own burner?

Of course, about the major production of the device with machining there is no need to talk about details. Most home enthusiasts often use diagrams with burner models assembled from off-the-shelf parts. Typical device made from a steel valve, plugs from metal cylinders and jets from These components will form the basis of the device. But it will also be necessary, based on the performance requirements of the device, to determine the parameters of the working tube. Again, the thicker and longer it is, the more effective the roof torch will be. You can make it with your own hands wooden handle, having it made to individual sizes. IN finished form Although such a device will not be reliable, it will be quite suitable for irregular small and spot heating.

Conclusion

In itself, the effect of flame on roofing material is effective, from the point of view of the possibility of its further reduction with neighboring areas. However, not every thermally exposed coating layer will be able to continue to provide its operational functions. Therefore, it is important to initially assess how appropriate roofing gas burners will be for solving specific heating problems. The price of the burner is small and averages 1 thousand rubles, but a damaged roof covering may make it necessary to completely update the “pie,” which will cost several times more. By the way, manufacturers of rolled roofing coverings often indicate in their descriptions how and whether it is possible to use such devices in laying their products. As such, the method of soldering bituminous and plastic materials is very attractive in terms of the performance properties of the resulting seam, but, for example, it is contraindicated for some film insulators.
