AIR-AND-FUEL BURNER OF COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 2010 - IPC F23R3/20 

FIELD: engines and pumps.

SUBSTANCE: air-and-fuel burner of combustion chamber of gas turbine engine includes fuel-spray nozzle made in the form of body with fuel supply and spray holes, air flow stabiliser, axial and tangential air swirlers equipped with confuser-diffuser nozzles with inner and outer path walls. Annular cavity is located between walls of axial swirler nozzle and outer path wall of the nozzle of tangential swirler. Perforation is made on diffuser part of the nozzle of axial swirler.

EFFECT: improving reliability of combustion chamber and increasing fuel economy of gas turbine engine at decreasing soot emission in exhaust gases, decrease of smoking and avoiding soot deposition on the burner surface owing to depletion of air-and-fuel mixture in local areas of the burner.
