The data is provided for indicative information only. All work with gas equipment, such as gas boilers, wall-mounted geysers and other water heating and heating devices, must be carried out by specialists who have all permits and licenses for working with gas and gas equipment. And the most important thing is to have experience working with such equipment, which will help you avoid common mistakes that can lead to the most negative consequences.

Portable gas burners are very popular both at home and in professional repairs. The scope of their application is very wide, and there are several varieties. You can choose the right burner for your current tasks and learn how to use it correctly by studying this article.

Main types of portable burners

Gas burners in the form of nozzles for cylinders with a collet connection must be considered as a separate class of tools. They are used in conditions of high fire safety at sites where heavy equipment does not operate. construction equipment and the risk of damage to the burner itself is minimal.

First of all, burners are characterized by temperature and flame shape. Most simple devices have a combustion temperature close to the minimum, only 700-1000 °C. Air enters the burner naturally, so it is always in short supply. At the same time, more expensive products have a special shape of air supply channels, due to this the air flow increases and the combustion temperature rises to 1200 °C.

Even hotter flames are produced by ejector-type burners, in which air flows to the hearth due to rarefaction, the flow force is directly proportional to the operating gas pressure. This allows you to raise the temperature to 1500-1600 °C and regulate it relatively smoothly along with the flame length with a simple twist tap. There may be several sources of combustion in the burner; such a tool is not intended for fine work, but it perfectly heats large areas.

The highest combustion temperature for burners is 2000-2400 °C and is achieved through the concentration of injected air in the combustion zone and the use of a special gas: methyl acetylene propadiene (MAPP). A high-temperature cone is formed in the torch flame, comparable in power and temperature to gas-oxygen welding, but not capable of autogenous cutting.

Optionally for all types of burners it is possible to have a flexible or rotary tube, piezo ignition and a highly sensitive control valve. Over a large temperature range there is the same wide choose burners in terms of power and corresponding gas flow.

Tourist burners

Low temperature burners solve a truly wide range of problems and are suitable for household use and professional construction. These blowtorches are most often used to replace electric hair dryers in places where only autonomous operation is possible.

The main disadvantage of burners without an injector is low flame stability, which is especially noticeable during sharp turns and tilts. The splashing of liquefied gas does not have a significant effect in burners over expensive class with a special gearbox and heating circuit.

As a rule, such torches are not used for soldering. Their main purpose is to ignite wood and coals or heat materials that can be used with an open flame. Such a tool is also indispensable for thawing pipes, heating car engines or unpacking tow strips, burning paint to remove it and other rough work.

Supercharged blowtorches

Ejector blowtorches have a more specific device and purpose. These are constant assistants of many designers and craftsmen in the processing of non-ferrous metals. The high temperature and adjustable flame make the torches ideal for soldering and hardening metals or other heat treatments that require high accuracy temperatures and a clearly defined cone.

Due to the specific application, the size of the burners and nozzles may vary greatly. Miniature ones are used for soldering jewelry and thin metal, despite the lack of pure oxygen supply, they can even cope with filigree work. Middle class burners have a cone thickness from 3 to 9 mm and the best way suitable for electrical soldering of connecting wires cable joints, copper and aluminum tubes.

Due to their high power, larger burners can be rationally used in industries such as artistic forging, precision bending or stamping of metal. These are the tools that home craftsmen use as the basis for homemade gas forges and hardening furnaces.

For ejector burners, the concept of an unstable flame is purely figurative, and although periodic flashes of gas are possible, the temperature in the core remains relatively stable. The gas preheating circuit is used more to improve the efficiency of the burners, to reach operating power faster and to accurately regulate the temperature.

High temperature gas burners

We cannot ignore burners that use MAPP gas instead of a propane-butane mixture. The flame combustion temperature in them is 2200-2400 °C, while the main energy is concentrated in a cone, which is quite stable and has a pronounced boundary.

Such burners are used for heating, forging and bending high-carbon steels and massive parts. High temperatures also allow for better quenching and tempering of metal.

In terms of soldering and welding, MAPP gas torches do an excellent job of stainless steel, while even thin parts do not overheat. Another advantage of MAPP gas is its low boiling point, which makes it possible to use it at temperatures as low as -20 °C even in burners without a heating circuit.

Choosing the best option

Choosing a gas burner for various tasks, you should pay attention to certain nuances. For tourist purposes, the simplest torch burners without pressurization are well suited. Even cheap Chinese products can handle lighting a fire or heating food; you don’t mind breaking or losing them at all.

For household purposes and minor repairs, it is better not to purchase tools from the amateur series. Slightly more expensive semi-professional burners have a more thoughtful design and are devoid of such non-obvious shortcomings as, for example, melting of the plastic lining of the mouthpiece or malfunctioning piezo ignition. Another argument against the average price category is the almost universal absence of a normal control valve, which even for rough work may be important.

If the torch is selected for fine work, soldering or welding, additional attention should be paid to ergonomics and balancing. During such work, the burner has to be turned on and off frequently, so the shape of the body and the placement of the controls should allow ignition and precise adjustment with one hand.

When choosing power, you should be guided by the thickness and material of the parts being processed. A 500-700 W burner will be quite enough for burning paint or soldering copper wires. Tubes made of non-ferrous metals and steel products up to 3 mm thick will warm up well with a flame power of about 1200-1500 W. 2-3 kW burners are used for heating and bending reinforcement up to 14 mm thick. There is one more feature: the flame of powerful high-quality burners can be adjusted for more delicate work, but it will not be possible to heat a massive part with a low-power burner.

The burner is the most important element any gas boiler, its “heart”, the stability of which directly affects the efficiency of the entire system. A correctly selected, installed and configured gas burner ensures uniform and complete combustion of fuel, and any, even small, malfunction in its operation can lead to serious consequences. Any gas equipment is a potential source of danger, and if it is not corrected in time, for example, “priming” of the burner, this can lead to the accumulation of gas in the room, which can cause poisoning and explosion.

Reasons to contact a specialized service center include increased fuel consumption, increased noise, repeated blocking of the device and the appearance of a gas smell.

A large assortment of burners of domestic, European and Asian production presented at Russian market, allows you to select the unit that optimally meets your requirements and financial capabilities. However, such diversity requires people carrying out repairs and service maintenance, thorough knowledge of the design and features of many models. And if a master who does not have special skills and expensive equipment can still cope with removing carbon deposits or cleaning the burner domestic production, then a non-specialist trying to repair high-tech Viessmann or Buderus equipment can, at best, lead to a decrease in the efficiency of the system, at worst, to a serious accident.
