Abstract
PURPOSE: To prevent oil from being remained in a system of the heavy oil used when a turbine is in operation, by using the fuel of light oil when the turbine is started and stopped in a gas turbine for which a different kind of fuel is used.
CONSTITUTION: In a path of oil line B1 linked to a light oil storage tank 22, a volute pump 24 where its delivery pressure is varied in accordance with its delivery flow rate and a check valve 28 are provided. While in a path A1 linked to a heavy oil storage tank 21, a gear pump 23 that produces a constant delivery pressure, throttling 30 and check valve 27 are arranged. And before and after the throttling 30 in the path A1, a bypass line A3 with a three-way solenoid valve 31 is provided. Further between the pipe line A1 and the tank 21, a fuel return pipe A2 having a pressure regulator valve 25 is provided. The both valves 25, 31 are actuated interlocking and open-close operated in accordance with a pressure difference between places before and after the throttling 30 to determine the feed amount of fuel to a turbine C. When the turbine is stopped, the regulator valve 25 is opened to return the fuel to the tank 21.
