FIELD: machine building.
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. Combustion chamber of gas turbine engine comprises fuel header, pipeline, fire tube including outer and inner rings, spacer plates, corrugated tapes, casings, inner and outer pockets, sealing rings, annular head, holders for suspension of flame tube, brackets, tie rods, housing. On bosses of housing are fixed with nozzle flanges. Output parts of nozzles are installed in the hole of swirler bodies, fixed with nut in burners of flame tube. Nozzle in the burner is made of shaped confuser shape. Output parts of nozzles are installed in bushing with annular lemniscate channel, which is arranged in swirler housing. Outlet part of nozzles contains holes. Plugs are installed in rear part of nozzles. Outer and inner rings of flame tube have cylindrical bushings.
EFFECT: invention is aimed at simplifying the nozzle design, improving combustion efficiency and improving fuel mixing.
