Gas burners for roofing: the characteristics and peculiarities

Gas burners for roofing is used to melt the bitumen coating and waterproofing of the roof during repairs. Also, the tool is used for drying a concrete and bricks, heating of metal and plastic in flexion. To work with the cylinder device requires a working gas. Features work tool selection and advice on the creation of design with their own hands - all this information is contained in the article.

Gas burners for roofing: what it is

Very often during the installation and repair of roofing work must be heated or dried material, for example when laying a waterproofing layer to create a soft or melt bituminous roofing mastic. To carry out the execution of these tasks will help roofing gas burner. With this device you can carry out several types of operations, namely:

• drying of surfaces and materials;

• cutting or welding metal parts;
• burning and removal of old paint layer;
• sealing of fine cracks;
• melting of mastic on the basis of bitumen;
• heating the sheet material prior to laying;
• hardening of seams and joints;
• other work which use to perform a high temperature is required.

Burner for roofing typically a torch with a hose and a balloon with fuel. This design is very convenient, reliable and mobile. The volume of the gas bottle may be different, with the torch hose has a standard form. flame is controlled by a regulator mounted on the device.

It is interesting! Roofing gas burner - is a specialized unit of gas-type, which is used to assembly and disassembly of soft roofing, as well as for drying of various building structures.

propane torches: Professional and low-end models

Experienced superintendents tend to buy expensive professional models that are reliable and safe to use. But the master of self-taught for home use should be fine simple and small structures. Consider further, the impact on the quality of the choice of this or that equipment.

Simple Burner is not intended for industrial activities where it is necessary to use almost every day. In this case, you will need a reliable model that can withstand running smoothly and to guarantee absolute safety. At the same time cheap and simple design in the hands of a skilled and careful master is able to serve for decades. Especially if it has to use only once a season.

Regardless of how the product is selected: and expensive professional burner with a balloon or household cheap construction - before each use, check the tightness of the product, especially the junction, the fuel hose and mouthpiece on clogging. If you miss even a slight defect, it can cause serious problems.

Useful advice! Even for home use should not buy the cheapest burner. Most likely, this model will be weak gearbox, which means that the tool performance will be on par with the power of a blowtorch. Working with such a device will go very slowly.

Gas burners for roofing on balloon or spray

At first glance it may seem that tighten the gas tank on the roof - the most dangerous idea, especially since the sale of fully hand burners. In fact, it is the torch on the can often cause burns, fires and injury. This is due to the sale of fake and cheap Chinese products. Safety burners with a large balloon is that the container itself during operation is located away from the flame.

When buying it is not necessary to pay attention to too cheap models. The main problem with such designs is that the data sheet indicates the operating pressure 0.05-0.08 MPa, which is several times higher than during operation. Reducer installed on the device, it is absolutely not designed for heavy loads, so the closed valve can simply not withstand such stresses.

Gas burners on the balloon: Device characteristics

Gas burner design includes a handle, the gas feed tube and fixed at its end a metallic glass. Hose connected to the handle, through which the working gas flows from the gas cylinder. The handle can be made of plastic or wood.

Glass gas burner is designed in such a way that during operation the flame was protected from the wind. Glasses of different models have different device, but the principle of operation is the same. Also possible flame length adjustment. Current models are equipped with special gear, which by the valve can be controlled by the pressure and fuel consumption.

By pressing the lever handle valve is opened and the gas flows into the glass through the tube and hose. The combustible mixture of combustion gas and air is ignited by a cigarette lighter or by conventional matches. Gas burner combustion temperature is very high and can reach from 500 to 1500 ° C.

Absolutely all models roofing gas burners equipped with supply air system. the device is also provided for adjusting the operation modes: operation mode and standby mode. For the manufacture of devices used exclusively quality and very durable materials, because the burner is heated up to the highest temperatures. Typically, a small weight of the structure varies from 1 to 1.5 kg, so the tool is easy to handle.

Modern burners for roofing different principle of adding oxygen to the fuel. Older samples require an oxygen tank, which is not very convenient. Modern designs take air from the atmosphere. Typically, the gas burner is used for propane, but there are examples of working on pure methane.

It is important! The length of the handle to hold the torch should have dimensions of about one meter, but not more. In this case, it is necessary that it is equipped with a special holder made of heat-resistant plastic or high-quality wood, so that the hands of masters protected from burns.

Gas burner cartridge: Instrument description

A burner nozzle for a gas cylinder with a push-in connection is used only with strict observance of the rules fire security, as well as in places where not working heavy construction equipment and the risk of damage to the spray gun minimal.

The simplest models have combustion temperature of about 700-1000 ° C. The oxygen enters the burner from the air, so it is always a disadvantage. In devices having a higher value, the flame temperature is 1200 ° C, while they have specific form of air distribution holes that contribute to the increase of oxygen quantity in burner.

Even higher flame temperature have manual gas burner ejector type. In these constructions the air is supplied to the fire due to dilution. With this flame reaches 1500-1600 ° C temperature. It is also possible with the crane relative to smoothly adjust the flame length. This model is not designed to perform delicate work, but that will suit for heating large areas.

All types of gas burners equipped with flexible or swivel tube, highly sensitive and pezorozzhigom valve for regulating the flame. Currently, there is a large selection of tools in accordance with its power and fuel consumption.

Gas burners for brazing: Features models

Ejector lamps for soldering are of particular structure and function. Most often, these tools use the wizard for non-ferrous metals. High temperature and flame adjustment possibility allows perfectly perform brazing and hardening metals or any other thermal processing that requires high accuracy and clearly defined temperature cone flame.

Dimensions spray burners and nozzles can differ significantly, which allows their use in various fields. Most miniature models are used for the soldering of jewelry and thin metal. Although the tool is not equipped with a device for supplying oxygen, but he copes with filigree work.

medium type fixtures have a cone thickness of 0.3 to 0.9 cm, and optimally suited for brazing copper and aluminum tubes. Burners large size due to high power to be used in artistic forging or stamping a metal.

For ejector burner flame application unstable notion is not entirely correct. Since, though it may from time to time flash, but on the flame in the core temperature of the tool is a little effect.

Gas burner for a roof: Packing material

Very often used in roofing roofing and waterproofing create quality of this material is impossible without the gas burner. You will also need a tool to cover the roof with melted kinds of modern materials.

The whole process of working with the burner can be divided into several stages:

1. First organized training bases for paving, it is necessary to clear it of debris. If necessary, it is possible to align the surface with a screed.
2. The entire surface is covered by the web material so that the sheets are formed adjacent overlapping width of 8.5-9 cm.
3. Aligning the marking material and performing rolls fold back and fasten using a burner at the base of the roof. To this end, the flame heated the lower part of the roll and the base of the roof, after which the material roll slowly unfolds and is pressed to the ground.
4. To prevent wrinkles and air bubbles must walk with a manual roller according to the attached web.
5. At the final stage should also use the burner with which the seams are heated material. After that, they also need to seal the hand roller.

Before use for the roof burners should be familiar with several important aspects:

• impossible to use the device at a temperature of 15 degrees below zero;
• if roofing work is performed at a low temperature state, it is permissible to use a liquid fuel burner;

• for use with high technical characteristics of the roof gas burner allows bed per day about 500-600 m roofing material;
• since the process is outdoors, the burner must operate smoothly and to have reliable protection against blowing wind.

• GW 500 is used to perform work surfaced during the laying of roofing materials. This model is easy to melt the bitumen. Flame temperature GW gas burner is 300 to 500 ° C;
• HS-850 - burner having a special valve, through which is possible to accurately adjust the amount of supplying process gas from the cylinder. Also here mounted lever, by which the master adjusts the flame length. This gas burner is not pure propane, and mixtures thereof, wherein the composition contains technical oxygen. Gas burner price roof HS-850 - 1700-2200 rub.

As you can see, the choice of gas burners is very broad, and where to buy the torch: in-store or online - depending on customer desires. The main thing - to read the characteristics of the model and check the quality certificates for the product.

Useful advice! GW-class models are suitable for heating ferrous and non-ferrous metals, melting of bituminous materials in a roll with the performance of waterproofing and roofing, as well as in cases where only the required application propane.

How to use a gas burner: safety regulations

Operation of gas burners requires strict observance of safety rules:

1. Work carried out with burners in overalls and shoe sole with non-slip. Also need the belt and the navigating bridge.
2. Before you use the tools necessary to carry out a visual inspection and to ensure good working burner, cylinder and hose connections.
3. In only one gas cylinder may be time application device at the work site.
4. One can not stand in front of the nozzle during the ignition of the gas burner. The direction of the metallic glass must be such that a fire could not touch any of the bystanders, the gas cylinder and hose connections.
5. In the case of the deposited material is required to make sure that they do not overheat and does not light up. It must be controlled so that only warmed the lower part, we can not allow the material softened completely.
6. Ignite the burner can be exclusively using matches or a lighter.
7. While working with the device master is forbidden to go beyond the boundaries of the workspace, and to descend or climb on Forests.

Quenching of the tool takes place in two stages: first, overlaps gas, and then the locking lever is released. Even with a small break in the device to be put out. If to be a significant break, the gas supply must be cut off and the tank.

Useful advice!If clogged mouthpieces or connecting hoses, you can not use the device, since there kickback and claps. In the case of reverse impacts or overheating should be immediately shut down and cut off the fuel supply to the cylinder. Cool tool can by soaking it in a container with water.

How to make a gas burner with their hands: Stages of manufacturing devices

To assemble the instrument virtually machining required. The gas burner is assembled from prefabricated elements. To do this, you need to prepare:

• propane reducer for the gas cylinder;
• cap, which is used for transporting the gas containers;
• jet from blowtorch - nozzle diameter is 0.8 mm;
• portion of the pipe having the following dimensions: length - 1 m, diameter - 1 cm thick steel - 2 mm;
• a wooden handle (suitable to the old non-working soldering iron).

Process of manufacturing a gas burner with their hands is not particularly difficult.

The first step is to insert the steel supply tube to the handle and secure with glue. The splitter housing and constructions made of brass rod 20 mm in diameter. In the finished package need to drill two radial holes (5 mm each), and four 1 mm holes in the rod deflector.

It takes a little tightness in the press in a splitter housing. The inner diameter of the body should be 0.6 mm larger than the diameter of the notch. The resulting gap is intended to inhibit the gas flow that is fed to the holes in the pilot light.

Next, you need to make the nozzle. Since the hole is very thin, the need to drill 2 mm diameter for its drilling. With it, the blind hole is created at a distance of 1.5 mm from the exit. Using the drill bit of 0.4 mm diameter, operate jumper.

The resulting hole should be completely zachekanit, for this will need to flip the hammer several times. Paper grinding until erode end until the nozzle can be put at the burner tube tip.

At the end of the tube is required to put the metering tissue-rubber hose for supplying gas. It should fix the collar. Then allowed to stand the working pressure and the gas is fed. Before setting fire to have to wait until the air is expelled from the nozzle.

Burner flame length should be 5 cm. The housing together with the divider fits the outer nozzle thread. It is important to ensure that the flame of a gas burner with their hands were smooth and without soot.

Useful advice! In that case, if the threaded joint has turned free, it can be sealed using FCM tapes.

Repair roofing necessarily require the use of hot air or flames. Melt bitumen melt roll roofing material or metal solder perform - data tasks perfectly cope gas burner for a roof. To perform a significant amount of work necessary to buy a reliable professional model, but you can create a design for his own household use.
