The invention relates to energy and can be used in furnaces for various purposes.

The aim of the invention is to expand the range of control and reduce weight and size characteristics.

The drawing shows the proposed burner, a longitudinal section.

The burner contains an air inlet housing 1 installed in it with the formation of central 2 and peripheral 3 air ducts, an annular gas manifold 4 with end outlet gas nozzles 5, paddle swirlers 6 installed in the peripheral air duct 3, lined burner plate 7 with openings 8, with the output gas nozzles 5 inserted in the opening 8 of the burner plate 7 with the formation of annular gaps, and the central air channel 2 at the inlet section is equipped with a device 9 for adjusting the flow section and Blade swirlers 6 are provided with end-turning sections 10 located in the zone of outlet gas nozzles 5. Air intake devices 11 are installed between the blade swirlers 6. A conical gas collector 12 is installed in the central air channel 2 with a gap 13 between the conical 12 and annular 4 gas manifolds .

The burner works as follows.

, 3, LZ 6 is twisted and fed to the mixture with the combustion products. In the channel 2, part of the air enters from the total flow through the device 9 to regulate the flow area and then through the gap 13, and part comes from the channel 3 through the device 11. The optimum amount of air entering the nozzles 5 is adjusted by the device 9. The length of the flare is adjusted the change of the turning sections 10 ЛЗ 6. 1 Il.

channels. The air from the central channel 2 enters the nozzles 5, and the air passing through the peripheral channel 3 is swirled with swirlers 6 and

enters the mix with the products of combustion. In the central channel 2, part of the air flows from the common flow through the device 9 to regulate the flow area and then through the gap 13, and part comes from the peripheral air channel 3 through the air intake devices 11. The optimum amount of air entering the nozzles 5 is controlled by the device

9. The length of the flare is adjusted by changing the position of the turning sections of the 10 vane swirlers 6.
