A mandatory element of an industrial device for burning gas is a gas burner. The scope of its application is heat generators, melting furnaces, boilers and other technological units.

Varieties, device, principle of operation

Types of industrial gas burners:

  1. Injection (atmospheric). Air is supplied to the combustion zone by injection (draft). Advantages: simple design, small size, low noise, reliability, long life.
  2. Blowing. With forced air supply with integrated fan. Disadvantages: high cost, noisy. Positive qualities: reduced carbon monoxide content, lower fuel consumption, independence from gas pressure.

The atmospheric burner in most units is an integral part of them and is included in the total price. Blasting is purchased separately and installed on the equipment.

Device device

The injection burner has an injector that serves to draw air from the atmosphere into the burner. They are divided into designs with incomplete injection of air and with complete mixing.

In the first embodiment, the combustion front is partially provided by air, the missing volume comes from the atmosphere. The device operates at low gas pressure. In the second embodiment, preliminary complete mixing of gas with air in front of the outlet openings takes place.

The industrial injection burner is equipped with:

  • primary air regulator;
  • nozzle;
  • a mixer;
  • collector.

At a blast burner, a gas-air mixture is formed directly in the burner. Air is forced by fan. The mixture of gas and air is fully mixed.

The fan burner is equipped with:

  • nozzle;
  • case with fan;
  • front plate;
  • ceramic tunnel.

A gas industrial burner can also be equipped with elements:

  • ignition device;
  • shutoff valves;
  • automation systems;
  • temperature and pressure sensors;
  • programmable electronic control unit.

General principle of work

At a given speed and direction, gas and air are heated to the required temperature. The incoming gas is mixed with oxygen and ignited at the outlet of the burner. During the process, the suction effect is important, in which rarefaction occurs in the tube with the gas under pressure. Air is drawn into the tube, connecting with the gas. The mixture is ignited by means of an ignition device.
