HIGH-SPEED BURNER Russian patent published in 2021 - IPC F23D14/02 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering, in particular, to devices for combustion of gaseous fuel and can be used in heating systems of drying, heating, thermal furnaces and other heating devices. High-speed burner comprises cylindrical housing with inlet air branch pipe, cylindrical-conical nozzle of heat-resistant material adjoining cylindrical housing, located inside cylindrical housing gas channel, connected by its one side with inlet gas branch pipe, and on opposite side of gas channel facing cylindrical-conical nozzle, its end wall has nozzle holes for outlet of fuel gas. Cylindrical housing, cylindrical-conical nozzle and gas channel have one common axis, gas channel is made annular, on its side facing the cylindrical-conical nozzle, there are tubular radial branches connected to the annular tubular header, on tubular radial branches and annular tubular header there are nozzle holes for outlet of fuel gas. Cylindrical-conical nozzle with its cylindrical part is put on cylindrical housing with possibility of relative displacement and has radial spacers connecting it with hub fixed by means of retainer on end of tubular cantilever located inside annular gas channel coaxially with it.

EFFECT: increase of unit thermal power of high-speed burner and provision of possibility to move flame burning flame in working chamber of heating device.
