Roofing gas burners

click fraud protection

The technology of the roofing device made of soft materials provides for the laying of the roofing sheet made of roofing material, possibly as a fireless method, using special solvents and fixing liquids that melt the bitumen layer of the coating or by fire, when the surface is heated with a gas burner and the roofing material is literally glued to the roof.

When using the fire method, appropriate equipment is also used for fast, efficient and mobile equipment in terms of moving over the roof surface - gas burners.

In addition, they also perform other roofing works:

  1. Preparatory - drying surfaces in inclement weather.
  2. Additional - the old paintwork is fired, the metal is heated or cut.
  3. Repair - the place of damage to the coating is precisely warmed up and compacted.

Description, device and principle of operation

Gas burner device
Gas burner device

Gas burners at their core Are portable torches that burn a mixture of propane-butane and air. Structurally, all manual gas burners consist of a metal cup, inside which there is a gas nozzle on a long tube, with a plastic handle or a handle made of wood with a regulator or tap to adjust the flow gas supply.

Gas is supplied from a cylinder through a pressure hose.

The principle of operation of the burner can be represented as follows:

  1. Pressurized gas is supplied through a hose to the tap on the burner.
  2. By opening the valve, the gas flow to the burner nozzle is regulated.
  3. A lighted nozzle delivers flame through the glass to the heated surface.

Most handheld roofing burners are lit with a match or lighter, but more modern types of tools are equipped with a piezo ignition, which makes them much easier to work with. The design of the glass is arranged in such a way that it sucks in air, and the ignited flame is not blown out even by very strong gusts of wind.

Manual gas burners are mainly used for roofing. But at the same time, the field of application of the tool does not end there, such a tool can be successfully applied in other construction and installation works where it is necessary fast local heating of materials, for example, when laying pipelines when waterproofing welded joints, when removing various coatings, when heating a bitumen mixture in road works.

Advantages and disadvantages

The handheld roof burner is today in fact the most effective tool for soft roofing applications.

This is largely due to the fact that:

  1. It has a low weight, on average about 1.1 kg.
  2. The regulator allows you to easily adjust the torch length.
  3. The comfortable handle made of heat-resistant plastic or wood allows you to work for a long time.
  4. The length of the burner allows you to warm up the roll coating without unnecessary movements.
  5. A special stop will prevent the nozzle from contacting the roof covering.

The disadvantages include:

  1. Small working radius, depending on the length of the gas supply hoses.
  2. Difficulty performing work at low temperatures - the propane gas mixture thickens, creating difficulties with ignition and flame regulation.
  3. Quite a large gas consumption during work.

To perform installation work on laying roofing from roll materials by fire, various types of gas burners are used, which have their own specifics and purpose.

Small class of burners GG-2

Gas burner GG2

In most ways, it is used for small jobs or in the household. This is due to the small size of the burner, its gas supply tube is somewhat shortened. But at the same time, this is a big plus when working in hard-to-reach places - for example, when laying the coating on air ducts, or repair work on small areas using small cylinders.

Burners type GG-2S

Gas burner GG-2S

Has two housings, which allows you to reach a higher temperature, and the valve available for each nozzle allows you to regulate the gas supply and find the best option.

GGK1

Gas burner GGK1

Specially manufactured for heavy work and is distinguished by increased reliability and durability, however, it is somewhat heavy.

GGS1-1.7

ГГС1-1,7 - gas burner

Widespread due to its low weight and relatively economical consumption of gas.

Burners type GV

HW gas burner

Both the GV-900 model and the GV-550 model have become widespread due to the ability to heat surfaces in full growth, while for the GV-900 models the flame torch can reach 900 mm, and for the GV-550 model - more than half a meter.

Roof roofing technique

The technology of covering the roof with soft roll materials by the fire method is carried out in several technological stages:

  1. Preparatory stage: preparation of a concrete base, filling cracks, garbage collection.
  2. Roll Base Layout, connection of joints, gluing of joints.
  3. Strengthening the foundation, planting it on a bituminous base.
  4. The base is heated with a manual gas burner and the roll cover is laid, pressed by the roller and, additionally, the joints of the rolls are processed with mastic.
  5. With a burner the base and the first layer of the coating are heated, and the top layer is laid.

Safety engineering

The main safety rules when working with a manual gas roofing burner are the general rules for hot work.

Special rules include gas safety rules, namely:

  1. Gas cylinders must be in good working order, have no visible defects and have a corresponding stamp of serviceability.
  2. Hoses should not have mechanical damage, cuts, cracks.
  3. Connections, including hoses, reducers, burners, must be sealed to prevent gas leaks.
  4. Smoking is prohibited during work.
  5. Gas roofing burners cannot be used at temperatures below minus 15 degrees Celsius, it is fraught with an explosion of the gas cylinder.

DIY making

DIY gas burnerThe gas burner itself is a very complex and responsible device. In its manufacture, it is necessary to apply not only the knowledge of metallurgy, because when heated, propane heats the surface to almost 1500 degrees.

You also need to ensure the tightness of the connection of all parts, including metal, and here you can not do without turning. In addition, the nozzle itself for the outlet of the gas-air mixture must be of a certain diameter, and it is almost impossible to achieve such an indicator at home.

Another method of manufacturing a gas burner is to use a nozzle from a gas welding burners, a glass can be made from a regular pipe, wooden planks can serve as a handle, and a valve will fit and tap.

WITHamu gas pipe is best made of brass, in extreme cases, of ferrous metal, but in this case it should be thin-walled for rapid cooling by the ambient air.

At the slightest sign of a gas leak, immediately stop work and turn off the unit, shutting off the gas supply both to the burner itself and to the valve of the gas cylinder reducer.
