Fuel inflow controlling device for gas-turbine engine combustor, has control system actively controlling fuel inflow, which is supplied to mixers of mixing device by using nozzle and activating valves based on signals received by sensor

摘要

The device (200) has a pressure sensor (218) detecting dynamic pressure in a combustion chamber of a gas-turbine engine combustor. A fuel nozzle has a set of supply stripes with loops (180, 182, 183) for supplying fuel to a pilot mixer and main mixer. A set of valves (184, 186, 188) is attached to the nozzle and are connected with the stripes. A control system (204) actively controls fuel inflow, which is supplied to the mixers of a mixing device by using the fuel nozzle. The system activates the valves based on signals (216) received by the sensor.
