FLAME TRANSFER PIPE OF A LOW-EMISSION COMBUSTION CHAMBER OF A GAS TURBINE ENGINE Russian patent published in 2023 - IPC F23R3/48 

FIELD: gas turbine engines.

SUBSTANCE: invention relates to ground-based gas turbine engines and can be used for combustion of gaseous air-fuel mixtures in the combustion chambers of gas turbine engines (GTE) and gas turbine plants. The flame-transferring branch pipe of the low-emission combustion chamber of the gas turbine engine contains flame-transfer tubes through which hot gases flow, connected coaxially with the bushing, and a latch. The sleeve is made floating, the flame transfer pipe contains two flame transfer tubes, the inlet diameter D1 of which is equal to 0.18-0.27 of L, where L is the distance between the two flame tubes at the installation sites of the flame transfer pipe, the flame transfer tubes are located coaxially one into the other along the connecting diameter D2, fixed with clamps and fit tightly to the flame tubes through floating bushings, the clamps are installed with one side into the grooves of the flame transfer tubes, with the other side attached to the grooves of the combustion chamber housing and are pressed against the wall of the front device during the combustion chamber assembly, a transverse flange with a seal is installed coaxially with the flame transfer tubes.

EFFECT: simplification of the design.
