COMBUSTION CHAMBER OF GAS TURBINE AND GAS TURBINE Russian patent published in 2020 - IPC F23R3/28 

FIELD: turbines or turbomachines; burners.

SUBSTANCE: invention relates to a combustion chamber of a gas turbine and a gas turbine. Combustion chamber of the gas turbine receives compressed air from the compressor, mixes compressed air with fuel, burns the mixture to produce combustion gas and feeds the combustion gas into the turbine. Combustion chamber includes: inner cylinder forming combustion chamber space inside; outer cylinder enveloping inner cylinder and forming cylindrical outer circular flow channel between inner and outer cylinders for compressed air passage; and a burner installed on the end of the external cylinder, which is located on the opposite side relative to the side of the turbine, and facing the combustion chamber space. Burner includes a cylindrical main body including a fuel distributing cavity and fuel nozzles located in a circle, if viewed from the combustion chamber space, and connected to the cavity. When viewed from the combustion chamber space, in the main housing there are slots extending in radial direction so that each of them separates adjacent fuel injectors from each other in circumferential direction.

EFFECT: invention provides reduced concentration of thermal stress on burner.
