FIELD: power industry. ^ SUBSTANCE: front device of annular combustion chamber of gas-turbine engine of ground units of various purpose includes fuel atomisers and air tubes with an inlet on one end and two opposite side outlets on the other end, which are equally located in a circumferential direction. Fuel atomiser is inserted in each tube. Inlet of each tube is arranged in the channel between combustion chamber housing and flame tube and directed towards the inlet of combustion chamber. Outlets of adjacent air tubes face each other. On inner surface of flame tube there installed is annular header of convex profile, which has the wall section common with flame tube, and at least one row of holes equally located in a circumferential direction (the first group of holes) on the side facing the initial part of flame tube. Outlets of air tubes are arranged in header. Each fuel atomiser in zone of outlet holes of air tube is equipped with two sprayers with through channels directed towards outlet holes of the tube at an angle to atomiser axis. ^ EFFECT: obtaining high fuel combustion completeness, decreasing emission of hazardous matters, and eliminating smoking. ^ 7 cl, 7 dwg |
