Choosing a gas burner for the roof. A roofing torch is a necessary equipment for installing a weld-on roof. How much do burners cost?

Gas roof burner - a device used for drying and heating materials, soldering and cutting metals, roasting old paint etc. The burner has a metal body (the glass protects the flame from being blown out by the wind), a nozzle (for ignition), a handle attached to the body (its length should be no more than a meter; the holder on the handle is made of wood or heat-resistant plastic), gas hose, supply tube (for supplying gas) with a valve (regulates the amount of gas supplied and the length of the flame), reducer (to save gas consumed, usually propane or a propane-butane mixture).

How to make a gas burner with your own hands?

A wooden handle can be taken from a burnt-out soldering iron. We select a supply tube with a diameter of 10 mm and a thickness of 2 mm made of steel. We insert it into the handle and fix it with glue. The body and divider are also machined by hand from a brass rod with a diameter of 20 mm. For oxygen access, we drill 2 radial holes with a diameter of 5 mm in the body, as well as 4 holes of 1 mm each in the divider rod (for supplying gas in the group of ignition holes). During assembly, the divider is pressed into the body with a slight interference fit. We install the internal flange into the housing with a mandatory gap (the internal diameter of the housing must be 0.6 mm larger than the machined diameter). This creates a gap necessary to slow down the flow of gas, which is supplied to the igniter holes.

How to make a nozzle with your own hands?

The nozzle is machined from a steel bar. How to make a thin nozzle hole with your own hands? We take a drill with a diameter of 2 mm, make a blind hole with it, not reaching the exit of 1.5 mm. For the jumper, a drill with a diameter of 0.4 mm is used. The resulting hole is completely caulked with light blows of the hammer. Next, we gradually grind the end with sanding paper until we find the desired cross-section of the outlet hole (when we can screw the nozzle onto the threaded tip of the burner tube).

We put the supply hose from the cylinder reducer made of rubber-fabric material onto the end of the supply tube and secure it with a clamp. By exposing operating pressure, apply gas and, after it displaces the air from the hose, insert the nozzle (excluding the body and divider) into the flame of the gas burner. We grind the end, achieving a burner flame length of 5 cm. We screw the body together with the divider onto the external thread of the nozzle. The burner should give an even flame, without soot. This is achieved by turning the body on the nozzle thread until the desired result is obtained. If threaded connection very loose, it needs to be sealed with FUM tape.

How to lay roofing felt using a gas burner?

Clean the base of the roof from debris. Roll out the rolls of roofing felt with an overlap of 85 cm, glue the ends to the base of the roof on one side, then roll the rolls back. Heat the base of the roof and inner side slowly roll out the roofing felt, press the roofing felt tightly to the roofing base with a roller, trying to avoid the formation of air bubbles and folds.

Gas burners have long been firmly established in construction life: they are used for cutting and soldering metal elements; burn old layer paints; dry the surfaces. They are also used for other work, but most often gas burners are used for roofing works. They heat bitumen and process the seams of covered roof surfaces. The main burner used is a propane burner, that is, one that runs on propane gas.

Gas-burner for the roof is a propane cylinder and a torch with a hose. How the gas flows through the hose and ignites is clear. But what really needs to be noted is this supermobility of the system and essentially reliable in use.

Gas cylinders can be of different capacities, but the hose and torch are the same. It is quite easy to control the flame because all the regulators are on the torch and therefore there is no need to be distracted by adjustments during operation.

Several models of roof burners

Quite today a large number of models. What are they for and what models are they:

Roofing and propane gas burners are indistinguishable in appearance, but they are divided into two different classes.

The difference between one type and another is in the use of cylinders: for propane there are standard ones used in everyday life and for welding work. They are quite easy to refuel - or rather, you just need to change them at refueling points. Guided by certain selection principles, you should note the difference in flame power and temperature(propane has more), and versatility - the ability to use when soldering and crimping pipes.

There is also a diesel roofing burner, which is a little safer than its relatives, but still, at the price of the fuel used, it has not caught on, at least in private construction.

Step-by-step process of working with a roofing gas burner

The process of working with a roofing gas burner is staged coverage roof insulation. One of the main elements of the coating is roofing felt.

Rules you need to know

• It is impossible to work with a gas burner if the air temperature below -15 degrees Celsius;
• at temperatures below -15 degrees Celsius, a diesel burner is used;
• using a gas roofing burner, you can cover an area of ​​up to 500 square meters;
• the roofing device requires reliable wind protection and a stable flame when fuel is supplied from a gas cylinder.

Safety Precautions for Propane or Gas Burner

Although everyone knows how to use burners, safety measures are never superfluous, and they consist of the following rules:

Conclusion

1. Propane or gas roofing torches are designed for roofing work on certain types of roofing.
2. What is a gas burner for roofing work? It is a glass with an attached handle and a nozzle inside.
3. Devices are selected according to the type of work performed.
4. Burners for roofing work allow, if necessary, to adjust the flame length and gas flow.
5. When working with the device, follow the rules and safety measures.

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 enough 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, pressurized propane 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 the 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 restoration practically not used. The burner is assembled from ready-made spare parts. To make it we will need:

1. A steel valve that can be taken from a cylinder intended for storing liquefied gas.
2. A plug used for transporting gas cylinders.
3. A nozzle from a blowtorch with a nozzle diameter of 0.8 mm.
4. A piece of pipe one meter long with an internal diameter of 10 mm. and steel thickness 2 mm.
5. 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 supply tube, which we will use as steel pipe, we insert it 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 the inhibition of the gas flow, which is supplied to drilled holes in the igniter.

To make a thin hole in our nozzle, you need to take a drill with a diameter of 2 mm. and use it to make a 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 set the working 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.

Carrying out roofing work or repairing old coverings involves laying materials and melting mastics using special device. A gas burner for roofing allows you not only to heat the material to the desired temperature, but also to dry its surface.

Such devices are also used to perform a number of other tasks:

• heating any workpieces and products to the required temperatures;
• cutting and soldering of metals;
• drying surfaces;
• firing old paint.

What kind of equipment is this?

As a rule, a gas burner for a roof is a metal cup with a nozzle and a handle attached to the body. The glass itself is assembled in such a way that the burner flame is protected from wind blowing. The gas enters the housing through the gas pipeline. Propane under pressure is often used for these purposes. There is a valve on the burner itself that allows you to regulate the amount of gas supplied. In addition to the intensity of the flame, its length can also be adjusted.

The propane roofing burner has a special gearbox that allows you to control fuel consumption, thereby reducing the cost of roofing work. In the vast majority of such devices, air is sucked directly from the atmosphere. To start the burner, use regular matches or a lighter.

Modern burners have a device that helps regulate modes. Thus, many models have a so-called standby mode, which allows you to reduce waste gas during breaks from work.

Since the flame heats nearby elements of the device to high temperatures, gas burners for roofing work are made from high-strength, heat-resistant materials. The length of the handle is often no more than 1 meter, while the weight of the burner does not cause discomfort when carrying out roofing work (up to 1.5 kg). To ensure that the burner operator does not get burned, the handle has a special holder made of wood or plastic that does not allow heat to pass through.

But gas burners for roofing are not the only solution in this segment. Quite often liquid fuel devices are used in construction. They run on fuel oil or diesel fuel. The design of such units itself is slightly different from that described above. In liquid fuel burners, fuel enters the combustion chamber under high pressure Thus, the liquid turns into a stream of small particles. At the exit from the chamber, the sprayed liquid is ignited, which creates the effect of a stable flame. A diesel roof burner has an advantage over a gas burner in that it allows you to work even at low temperatures.

Stages of work when laying material using a roofing torch

The entire work process can be divided into several stages:

• preparation of the base. For these purposes, it is necessary to clear the base of debris and, if necessary, level it using concrete screed;
• rolls out across the roof area roofing material. In this case, an overlap of 8-10 cm is maintained. After aligning the strips of material and applying markings, it is rolled back into rolls, while securing the beginning of each strip to the base;
• A gas burner for roofing is used to heat the bottom of the roll of material and the base of the roof. Then the roofing material is carefully rolled out, pressing it against concrete surface;
• after fastening, a rolling roller is passed over the canvas, which allows air bubbles to be removed from under the material;
• propane torch for roofing work is also used on last stage works It is necessary to warm up the overlapping seams of the material. After this, they are additionally passed over with a roller.

Roofing work using gas burners is only possible at air temperatures of at least 15 degrees below zero. If it is necessary to carry out roof repairs in more harsh conditions, then it is imperative to use a liquid fuel burner.

When using a gas burner good quality in one working day it is quite possible to lay up to 600 meters of roofing material. A high-quality burner, in addition to flame stability, provides reliable protection from the blowing wind.

Roof burner models

For roofing work, burners are used completely various types:

Safety rules when working with gas burners for roofing

The roofing propane gas burner must be operated in strict accordance with safety regulations.

Roofing work on the roof can only be carried out in special clothing and shoes with non-slip soles. In addition, it is necessary to use various additional devices - walking bridges, a belt, etc. Before starting work, you should inspect the burners and make sure that all cylinders and hoses are in good condition, check the tightness of the connection between the hose, cylinder and reducer. When carrying out the work itself, it is necessary to keep in mind that there should be only one gas cylinder at the work site.

You can light the burner only while standing on the side of it. During operation, the burner flame is directed so that it does not touch people or elements of the burner itself. gas installation. If you are using a self-assembled roofing burner, then special care must be taken.

Overheating of deposited materials must not be allowed. It is important to ensure that only the bottom layer of material is subjected to melting, while preventing softening of its main fabric. The burner must not be ignited from random sources of fire. For these purposes, only a lighter or matches are used. When lighting a gas (propane) burner, you must first open the gas supply valve halfway. After a few seconds of purging the system, you can ignite the mixture. The field of this valve regulates the height of the flame.

When the burner is on, it is prohibited to go beyond the limits working area or climb the forests.

Extinguishing the burner is carried out in two stages. First, the gas supply valve is tightened, then the locking lever is lowered. During breaks in work, the burner must be extinguished, and if it is long, the gas supply is also cut off.

If the inlet channels and mouthpieces of the burner are clogged, it is prohibited to begin work. Such clogging is fraught with the occurrence of reverse blows or pops. If the burner overheats or backfire begins to be felt, then work with the equipment must be stopped immediately. In this case, the gas supply is shut off, and the burner itself is cooled in a container with ordinary water.

conclusions

This type of equipment, such as a gas or liquid fuel burner, can significantly increase the productivity of work when laying a fused roof (detailed article: ""). But due to the fact that such equipment is a source increased danger, work with it should only begin after a detailed study of the instructions and safety precautions. You need to work especially carefully if you are using a roofing gas burner that you assembled yourself. Adoption necessary measures is the key to high-quality roofing work without any incidents or shortcomings in the resulting roofing pie.

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 roof 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 different types, the main difference 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 burners are allocated to a separate group. The most important difference 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 burners, including propane burners, only from proven trading enterprises who 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. The created mixture, after ignition, 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 are used somewhat less frequently than gas burners; even on sale, diesel models are not so common.

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, 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 visual inspection 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) person at the workplace. gas cylinder. 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 igniting a propane burner, open the valve half a turn. Once the flame has lit, 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 along 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 roll material overheating must not be allowed. 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 area is completed, since the bitumen layer has 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.
