Gas burners for spray can: varieties and principle of operation + nuances of choice and use

Some technologies of construction, installation of pipelines, car repairs are associated with the use of directional open flame. In everyday life, gas spray burners are popular - small appliances that allow you to adjust the direction, strength and temperature of the fire.

Models differ in purpose, design, type of fuel, so before buying, you must consider the main criteria and purchase a device that is not only convenient, but also economical.

To facilitate the task of selection, we prepared a detailed classification of portable burners, provided practical recommendations for determining the best model, and also outlined the rules for the safe operation of gas devices.

Types of Portable Burners

Gas burners are devices that are different in design and purpose, but they share a common feature - the operation is made from gas.

Portable devices designed to work from a small tube filled with propane-butane or other gas should not be confused with ovens or powerful welding units that run on natural gas or a large bottle.

We offer a brief overview of the basic structural elements of an inexpensive burner for a gas spray, which serves as an excellent example of a home appliance. It can be useful for repairs in the country or for a barbecue.

Using a compact device, you can quickly ignite the brazier, heat bolts or nuts in the cold, melt plastic parts, and process heat shrinks. The flame temperature (up to + 1300 ° С) is enough for soldering metal pipes.

This is an example of a burner popular among users of the type, but the range of devices is much wider. Consider the most popular species.

Difference in use

An open flame may be required both at home, and on vacation, and during installation work. One of the areas of application is tourism. In camp conditions, using a simple device, light a fire, heat canned food.

The devices for heating food have a special design - instead of a muzzle nozzle - a long thin hose for supplying gas to an external burner with a stand

Torches with a directed torch of "pistol" type are often used in installation work at soldering copper pipes, for bending plastic elements.

The flame, heated to the desired temperature, is directed to the mating zone of the copper parts, resulting in a solid permanent connection of the pipe with the pipe or fitting

High-temperature powerful lamps can also process steel parts, but this requires solid solder and a slightly modified soldering technique.

Portable gas burners are also used for the following operations:

• processing of wooden parts;
• ignition of a barbecue grill, a bonfire in the country without the use of chemicals;
• calcination and cutting of metal billets;
• singeing carcasses of animals during cutting;
• thawing frozen pipelines.

A useful device is always at hand from skilled craftsmen who independently love to improve their home and improve their personal plot. The burner can be useful in the workshop, during the construction of the greenhouse or other structures.

Division by the method of attaching the spray can

The fuel cartridge is a consumable item. As soon as the fuel runs out, it is disconnected from the burner, and a new spray can is installed in its place.

There are several types of cartridge attachment to the device:

• threaded - are fixed with the help of a thread, in other words - they are wound;
• collet - put on and slightly turn in one of the parties;
• valve - are fixed by a clamp;
• piercable - connect with a light touch.

Threaded models are more common than others. They form a strong connection of two elements that can be disconnected at any time. Pierced, on the contrary, can not be turned off until the gas in the can is over.

Collet devices are quick to install. To fix them on the tank, you just need to put on and turn 25-30 degrees to the side

The weak side of the collet devices is the quick loosening of the lock, resulting in gas loss.

Valve burners, which are usually designed to heat food, are considered more reliable.

The difference between gas burners by type of fuel

Manufacturers use a variety of fuels to fill consumable cartridges. The choice of liquefied gas is based on the purpose of the burners, the required flame temperature, power. To improve the characteristics of the composition, several different types of fuel are sometimes mixed.

Most often, the following combinations of substances are used:

• a mixture of propane and butane (70:30) - mainly for summer use, but with a heating device it is also used in winter;
• combination of propane, butane and isobutane in various proportions;
• MAPP mixture - methylacetylene-propadiene-propane, more often used for welding at a temperature of 1600-2500 ° C.

But there are cans filled with any one gas, for example, butane.

A sample of inexpensive gas cans is the Pathfinder. The price is 90 rubles. Filling - universal gas fuel suitable for portable burners, cutters, stoves, heaters

The choice of fuel is important when work is required in harsh conditions - in the cold or at high altitude. And in the summer, any universal gas is suitable for igniting a barbecue or bonfire.

Design features and principle of operation

The design of the burner varies from elementary appliances with a nozzle to more complex mechanisms equipped with an air supply device and piezo ignition.

Consider the design of a torch designed for welding metal.

Burner device: 1 - nipple for connecting an oxygen sleeve; 2 - nipple of accession of an acetylene sleeve; 3 - oxygen supply valve; 4 - fuel supply valve; 5 - oxygen channel; 6 - acetylene channel; 7 - check valve; 8 - injector; 9 - mixing chamber; 10 - case; 11- union nut; 12 - a sealant; 13 - supporting spring ring; 14 - groove; 15 - tip; 16 - mouthpiece; 17 - an additional channel for oxygen; 18 - sealing surface (+)

The injector and non-return valve design increases productivity and reduces fuel consumption.

Almost all portable household appliances belong to the so-called injection burners, when air is naturally sucked into the burner to support the flame.

Inside, in a special chamber, fuel is mixed with air, as a result of which the fuel ignites after a spark is supplied.

By adjusting, which not all burners are equipped with, it is possible to achieve the required size and power of the torch. High-temperature devices are distinguished by a bluish-blue flame, low-temperature ones - yellow-orange

From the mixing chamber, the gas mixture enters the nozzle nozzle, where it is distributed through the channels. At the end of the structure, in the place of formation of the torch, fire holes are located - the end of the channels.

Options nozzles on the structure: ring, slotted, tubular.

Optimum Burner Tips

Compact hand burners they buy with pleasure, so they have a lot of advantages over liquid-fuel, more "serious" devices. They are quickly set on fire, almost do not get dirty, require a minimum of care.

Using the manual model is easy: the flame power can be adjusted, and the torch can be directed at any angle, which is important when working in cramped circumstances

Criterion # 1 - the scope of use of the device

First of all, it is necessary to determine exactly what the gas device will be used for, since soldering burners and for warming up food radically differ both in design and in parameters.

Travel devices are in the form of a stand and resemble a household gas stove, on which it is convenient to install dishes with heated food

Construction appliances often resemble a gun in shape. When working, it is convenient to hold them with one hand, and with the other at this time, you can support the part or bring solder.

Criterion # 2 - model specifications

Features such as weight and size are important if you have to take the burner on hiking trips or use it often in everyday life. A heavy tool causes rapid fatigue, while a light tool is much more convenient.

We draw attention to such characteristics as:

• flame temperature - from 480 to 2500 ° C;
• heating temperature - from 550 to 2500 ° C;
• power - 0.5-3 kW;
• the ability to connect cartridges with different fuels;
• a method of attaching a cartridge to a burner;
• type of flame, torch shape;
• fuel consumption - from 60 to 1000 g / h;
• weight - from 50 grams to 1.7 kg.

If you purchase a burner specifically for brazing copper pipes, then the low-temperature model is suitable.

Cutting or welding steel parts will require a more powerful machine, which is usually called a torch or welding lamp.

Overview of additional useful options:

It is not surprising that portable devices are popular, but when buying, you must take into account all the nuances, including technical specifications, design features, cost-effectiveness, ease of use.

Rules for safe use

Work with combustible materials and open flames is always a risk, so when using even a simple hand-held device, you must follow the safety rules.

First of all, you need to get acquainted with the design of the device, carefully study the operating instructions and in the future, take all the manufacturer's recommendations into account (+)

Overheating of the cylinder, which can provoke a close location of a heat source, such as a fire or stove, is inadmissible. The can can explode and cause sharp injuries to the torn housing. It is also not recommended to leave it in the sun.

Special care requires professional devices that are usually used for a long time. Suppose, in order to maintain the functions of the burner and the power of the torch, after prolonged use, the device is packaged in a catalytic heating pad.
