COMBUSTION CHAMBER OF A GAS TURBINE AND METHOD FOR MANUFACTURING A BURNER PART Russian patent published in 2021 - 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 burner part moulded by means of three-dimensional additive manufacturing, wherein said burner part includes a first section used in a first temperature range and/or a first voltage range, and a second section used in a second temperature range lower than the first temperature range, and/or in the second voltage range lower than the first voltage range, wherein the lamination rate whereat the metal material is laminated in the first section by means of three-dimensional additive manufacturing is lower than the lamination rate whereat the metal material is laminated in the second section. The burner part constitutes a perforated plate mixing the fuel with air. The first section is located on the perforated plate on the side of the flame, and the second section is located on the perforated plate on the opposite side from the flame. The lamination rate whereat the metal material is laminated in the first section and the lamination rate whereat the metal material is laminated in the second section are switched continuously.

EFFECT: invention provides a possibility of suppressing the formation of a high-temperature flame and implementing uniform burning.
