GAS TURBINE PLANT COMBUSTION DEVICE Russian patent published in 2018 - IPC F23N5/10 F23R3/28 F23R3/34 F23R3/36 

FIELD: fuel combustion devices.

SUBSTANCE: invention relates to the gas turbine plant combustion device. In the gas turbine plant combustion device 3, plate with the air holes 20 includes the air holes central group 51 made up of plurality of air holes 51A and 51B and plurality of the air holes outer circular groups 52 made up of the air holes plurality 52A, 52B and 52C and formed so, that to surround the air holes central group 51. Gas turbine plant combustion device includes portion 601 with hole and temperature sensor 401 provided on the air holes plate 20, located in the area surrounded by two air holes outer circular groups 52, adjacent to each other and the air holes central group 51. Wherein, the device also includes the refrigerant supply source 220, cooling pipeline 205, which connects the portion 601 to the opening and the supply source 220, valves 67 and 68 provided in the cooling pipeline 205, and control system 500, which actuates the valves 67 and 68 based on the measured by the temperature sensor 401 value. Object of the present invention is the gas turbine plant combustion device structure excessive temperature rise suppression and ensuring the gas turbine plant combustion device reliability.

EFFECT: provided is the gas turbine plant containing combustion device.
