COMBUSTION CHAMBER OF A GAS TURBINE Russian patent published in 2021 - IPC F23R3/06 

FIELD: engine building.

SUBSTANCE: combustion chamber of a gas turbine includes a combustion sleeve forming a cavity of the combustion chamber whereto fuel and air are supplied to develop combustion gas, a sleeve attached to the outer circumferential surface of the combustion sleeve to form a space with said outer circumferential surface, and a pressure dynamics damping hole formed in the combustion sleeve equipped with a sleeve for communication between said space and the cavity of the combustion chamber, wherein the combustion chamber of the gas turbine comprises a guiding shield for the cooling air installed on the inner circumferential surface of the combustion sleeve to form a film-like air flow around the area wherein the pressure dynamics damping hole is formed. A cooling hole is formed in the combustion sleeve downstream from the sleeve for entrance of air into the cavity of the combustion chamber, and the guiding shield for the cooling air is installed in the position corresponding to said cooling hole.

EFFECT: invention provides a possibility to reduce the concentration of nitrogen oxide emissions.
