Air-gas burners: the seven best offers + selection criteria and tips for use

Many operations performed during repair, construction and roofing work require exposure to high temperatures. It is about heating, drying, soldering, firing, fusion of various elements. For these purposes, a multifunctional improvised tool is needed - a gas-air burner.

The market offers many options for equipment for flame treatment. We will talk about their device, the pros and cons of the tool. We will give useful recommendations on the selection and use of burners, consider the most popular and popular models.

TOP 7 best modifications

HS burners, operating on the principle of burning a mixture of air and propane-butane, are called portable torches. They work from a gas cylinder, are affordable, have a simple design, compact dimensions and light weight, do not cause difficulties in operation.

Due to reliability, safety and a sufficiently high efficiency, mobile burners are widely used not only in construction. They are used to solve all kinds of domestic, economic, industrial problems.

The principle of operation of the equipment is simple: a combustible substance under pressure is supplied to the valve through a hose, enters the mixing zone with air, after which the nozzle releases a flame onto the surface to be treated through a glass (mouthpiece)

Despite the general similarity, burners differ in certain features, technical characteristics, can be equipped with additional functions, have a narrower or wider purpose.

One of the compact types of equipment are gas spray gunsattracting by its small size and mobility. To solve one-off problems, manufacturers have proposed a number of mini burner, which in everyday life find a wide front of application.

Recommendations for the selection of hot water burners

In order to choose a reliable and functional burner that would cope well with the tasks, you need to understand the features of its design and take into account several important criteria. The correctness of the choice of such a product depends on this.

Let us single out several key criteria for selecting hot water burners:

1. The length and weight of the device.
2. Working gas.
3. Heat flow rate.
4. The diameter of the mouthpiece.
5. The method of regulating the strength of the gas flow.
6. The method of ignition.
7. Heating temperature.

Next, we consider in more detail the main parameters that you should look at before buying.

Cup diameter and burner length

The first thing you should pay attention to is the mouthpiece or glass mounted on the tip. It should be made of high-quality heat-resistant materials that localize the ignited flame and protect it from gusts of wind.

The diameter of the glass can be from 30 to 80 mm and is selected depending on the required fire power. The wider the glass, the more powerful and abundant the generated flame will be.

The design of portable hot-water burners consists of a metal cup, a shut-off valve, an extension tube-hose through which oxygen and combustible gas are supplied, as well as a holder-holder. The device is equipped with an external air suction system

An important functional nuance is the length of the burner. Short devices up to 50 cm long are suitable for partial repair, local heating, melting of individual sections of the material. For more voluminous work, it is more advisable to choose burners from 80 cm.

Flame power and equipment weight

The next moment is the power of the gas flow to the nozzle, which determines the strength and length of the flame. Often this parameter is controlled by a valve. In some models, there is a lever valve that allows you to use the device in working and standby (standby) mode.

In standby mode, a small flame is maintained at a minimum gas flow rate, which can significantly save fuel when there is no need to use the device at full power. In addition, torches with a lever are more convenient: they do not need to constantly unscrew and tighten the valve

Most fixtures are ignited by a regular match or lighter. Upgraded burner options are equipped with a piezoelectric element, providing a more convenient ignition.

The temperature of the exhaust flame can reach 1500 ° C or more. The maximum possible parameters are selected taking into account the intended type of work and the specific operating conditions of the burner.

Equipment for roofing is supplied with several gas-air installations - nozzles. Some products are equipped with additional nozzles for different types of operations.

The approximate weight of devices depending on the model is 0.5-1.5 kg. This parameter is influenced by the design and functional features of the device. The weight should make it easy to hold the device in hands and not cause excessive physical fatigue, which greatly limits the duration of work.

Production material and equipment

It is also necessary to look at the materials of which the burner is made. Since the device heats up to high temperatures during operation, they must be high-quality and heavy-duty.

In order not to get burns during various operations, you should carefully select the handle. It is important that the handle is equipped with a holder made of heat-resistant plastic or durable wood.

Devices differ in the type of fuel source used. Basically, the devices operate on propane or a propane-butane mixture. They show high performance, are safe and affordable. Methane serves as an alternative to propane, but it is used mainly in professional operation.

Before you purchase a device, be sure to check the reliability of the connecting hose, the tightness of the joints and joints, the integrity of the glass. Any undetected defect can lead to serious consequences.

Operating Precautions

The hot water burner, like any tool that forms a flame during operation, is a means of increased danger.

Therefore, applying it, it is necessary to observe a number of rules that will help to protect yourself and others, as well as qualitatively carry out the planned processes:

• regularly conduct a preliminary inspection of the structure, make sure that the equipment is in good working order and that there is no risk of gas leakage due to a damaged sleeve or joints;
• during ignition of gas, do not stand in front of the nozzle, do not direct fire towards the gas cylinder, hoses, people;
• during the deposition of various materials, carefully control the flame, avoid excessive heating and accidental fires;
• Do not go beyond the working space with the device;
• don't work close gas cylinders or gas pipelines - The safe distance is at least 10 meters.

Fire extinguishers, boxes of sand should be present at the workplace to help suppress the source of fire in case of fire. If the connecting hose or glass is clogged, the appliance must not be used. This can be indicated by claps, back strokes, equipment overheating.

Having identified such problems, turn off the device by cutting off the fuel supply. Do not use wire or other sharp objects to clean the mouthpiece.

To protect your eyes from the harmful effects of infrared and ultraviolet radiation, it is advisable to use special glasses with light filters.You need to work in clean, not oiled overalls, non-slip shoes

In addition, the device must be properly extinguished. First of all, the fuel supply is shut off, and then the lever is released.

It is not recommended to leave the tool turned on during breaks in work: it is better to extinguish the flame. If a significant break is planned, it is necessary to shut off the gas supply on the cylinder by turning the gearbox valve.
