DEVICE FOR BURNING FUEL IN ROTATING FURNACE

摘要

FIELD: combustion. ^ SUBSTANCE: device comprises housing of the exit nozzle made of a conical recess whose generatrix is inclined to the axis of the housing at an angle of 25-35°, fuel supply needle arranged in the zone of the conical recess of the exit nozzle for permitting movement with respect to the exit nozzle and mounted with a spaced relation to the nozzle, passage for supply of oxidizer defined by the outer surface of the fuel-supplying needle and inner side of the nozzle housing, and chamber for supplying secondary air . The end part of the fuel-supplying needle is shaped into a cone with an inclination of 3-4° to the housing of the nozzle and projects out of the narrow part of the nozzle by 0.6-1.5 mm. The passage for supply of oxygen is connected with the system for supplying overheated steam. ^ EFFECT: reduced flow rate of fuel. ^ 2 dwg
