FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbine engine building, in particular to designs of combustion chambers of gas turbine engines, ground gas turbine engines used as drive of supercharger of gas transfer unit or electric generator. Fuel-air nozzle comprises swirler housing including blade swirler, cone-shaped mixing bushing, nozzle body containing inner channel with installed screw and throttle washer, sealing rings, throttling washer and crown nut. Mixing bushing has an elongated conical shape with transition to a cylinder with holes on the cone and a chamfer in the outlet section of the cylinder; a sprayer is installed in the internal channel of the nozzle housing and contains perforated tubes located at the outlet of the swirler.
EFFECT: invention allows improving combustion completeness, ensuring high quality of mixing fuel with air, ensuring minimum non-uniformity of temperature at nozzle outlet, reducing emissions of hazardous contaminants, ensuring high reliability of nozzle operation.
