GAS TURBINE COMBUSTION CHAMBER AND PLANT WITH COMBUSTION CHAMBER (VARIANTS) Russian patent published in 2018 - IPC F23R3/16 

FIELD: fuel combustion devices.

SUBSTANCE: combustion chamber of the gas turbine comprises a body forming an outer boundary of the combustion chamber, fuel injectors disposed in the housing and connected to a fuel source, a heat pipe, a flow tube, a transition part, a resonator and an annular passage between the flow tube and the housing, the resonator being located in the annular channel. Flame tube is designed to receive fuel and air from the fuel injectors and limits the combustion zone. Flow nozzle is located between the flame tube and the body and is intended for distributing the air discharged from the compressor to the head end portion of the combustion chamber and to cool the flame tube. Transitional part is connected to a flame tube and is designed to supply combustion products to the turbine. Resonator is located adjacent to the flow nozzle upstream of the transition part and is designed to reduce the pressure fluctuations generated by the combustion process.

EFFECT: invention is aimed at reducing pressure fluctuations generated by the combustion process.
