GAS-TURBINE ENGINE COMBUSTION CHAMBER Russian patent published in 1998 - IPC

Abstract RU 2121112 C1

FIELD: gas-turbine engines for aviation and surface power plants. SUBSTANCE: flame tube 1 of combustion chamber has stepped adapter 9 in cross section formed by wall 10 and surface 11. Stepped adapter 9 is made between adjacent flame tube in circumferential direction between longitudinal axes 14 and 15. Area of outlet section of flame tube is equal to 50-100 percent of area of gas receiver cross section in plane of stepped adapter. Each flame tube is provided with front wall fastened to wall 10 of flame tube 1 at its outlet end 13; it is movable along longitudinal axes 14 or 15. Adjacent front walls are interconnected for motion in transversal direction in plane relative to longitudinal axes 14 and 15. EFFECT: reduced level of emission of NOx in turbine waste gases; enhanced reliability; increased service life at reduced overall dimensions. 4 dwg
