GAS INJECTOR BURNER Russian patent published in 2010 - IPC F23D14/02 

FIELD: power industry.

SUBSTANCE: gas injector burner includes gas chamber formed with cylindrical side and end walls and equipped with gas supply branch pipe, a row of mixing shafts tightly installed in end walls of gas chamber in a circumferential direction, passing through it and having gas nozzle made with an inclination towards air flow and located in gas chamber, and air fan; gas chamber is equipped with cylindrical partition and its cylindrical side wall and passing between two adjacent shafts, and gas supply branch pipe is connected to cylindrical side wall of gas chamber and arranged near one of the shafts separated with a radial partition. Burner includes the second row of mixing shafts tightly installed in end walls of gas chamber in a circumferential direction, which is concentric to the first one; gas chamber is equipped with additional cylindrical partition separating the second row of shafts from the first one, connected to radial partition on one of its sides and having feedthrough hole on its other side; the number of gas nozzles in each shaft is increased to 8 and more; at that, nozzles are made with an inclination in tangential direction, and nozzles of various rows are inclined to opposite sides.

EFFECT: increasing the working gas pressure coefficient of burner up to 25-100%, eliminating flaps and failure of flame during lighting-up.
