BURNER Russian patent published in 2015 - IPC F23D14/02 F23D14/62 

FIELD: energy engineering.

SUBSTANCE: invention relates to the field of energy engineering. The gas injector burner comprises a flame stabilizing tunnel, a flame-retardant ramming mixture, 13 cylindrical mixers joined by a common welded gas distribution chamber, in each mixer four nozzles are drilled at an angle of 24° to their axes, comprises a housing welded to the cylindrical gas distribution chamber, in which the flame-retardant ramming mixture is stuffed, the cast flame stabilizing tunnel for peripheral torch which fits over the housing and welded to it around the perimeter, the cast flame stabilizing tunnel for the central torch, and the burner comprises a device for adjusting the air flow rate, in addition the cylindrical gas distribution chamber comprises in the centre a central mixer with a nozzle having sixteen cast ribs on the inner surface, and at its periphery twelve peripheral mixers without nozzles with cast ribs on the inner surface, in addition, for fixing the burner to the heat or the melting unit a steel disc is provided, welded to the upper part of the flame stabilizing tunnel for the peripheral torch.

EFFECT: invention enables to obtain a long flame during gas-air mixture combustion in the centre and the periphery, to extend the lifetime of the burner, to improve the process of stuffing and setting the burner in the heat or melting unit, to adjust the air flow rate.
