GAS TURBINE COMBUSTION CHAMBER FOR COMBUSTION OF HYDROGEN-CONTAINING MIXTURES Russian patent published in 2025 - IPC F23R3/00 

FIELD: machine building.

SUBSTANCE: invention relates to gas turbine engineering, namely to combustion chamber, specifically to burner of stationary power gas turbine plants for efficient combustion of hydrogen-containing mixtures. Proposed burner device of the combustion chamber is made modular, with possibility of its removal for disassembly and repair. Front plate of unit of fuel injectors is installed with possibility of its displacement along axis, repair and replacement without disassembly of entire combustion chamber. Fuel injectors are made of two cylindrical tubes of different diameter, external and internal, pressed into external and forming a narrowing section of the fuel channel. Inner tube of the fuel channel is installed with an outer outlet from the end of the outer tube. Ends of outlet of internal tubes of fuel injectors are installed without a gap to the end of the front plate. Difference in diameter of concentric circles, on which the second and third rows of fuel injectors of the main circuit are located, is equal to value of diameter of air hole of front plate.

EFFECT: improving operational reliability of the combustion chamber at simultaneous simplification of its design, control algorithm, as well as improving maintainability and simplicity of maintenance at providing low level of NOx emissions.
