COMBUSTION CHAMBER OF A GAS TURBINE AND METHOD FOR MANUFACTURING A FUEL NOZZLE Russian patent published in 2022 - IPC F23R3/00 

FIELD: combustion chambers.

SUBSTANCE: invention relates to the combustion chamber of a gas turbine. The combustion chamber of a gas turbine comprises a fuel nozzle moulded by means of three-dimensional additive manufacturing, the fuel nozzle has a first area wherein the metal powders are sintered and a second area surrounded by the first area, wherein the metal powders are not sintered. The fuel nozzle has a second area between the fuel flow channel extending from the end section at the base of the fuel nozzle to the front end section thereof and the external circumferential surface of the fuel nozzle. The fuel nozzle has a second area between the fuel flow channel, excluding the end section at the base of the fuel nozzle, and the external circumferential surface thereof. The fuel nozzle has a second area between the fuel flow channel including the end section at the base of the fuel nozzle and the outer circumferential surface thereof, and a second area is absent in the fuel nozzle between the fuel flow channel, excluding the end section at the base of the fuel nozzle, and the outer circumferential surface thereof. The second area is divided into multiple sections in the axial or circumferential direction of the fuel nozzle.

EFFECT: invention provides a possibility of increasing the dispersion capacity of fuel, reducing the vibrational stress.
