Abstract

PURPOSE:To decrease the change of temperature of steam by controlling the inflow amount of the steam to the turbine equipping a bipath pipe line as well as a control valve to a steam supply pipe line. CONSTITUTION:The exhaust return boiler apparatus 14 of a gas turbine apparatus 2 and a steam turbine apparatus 24 are communicated through a water supply pipe 36, a steam pipe 38. A control valve 42 is provided on a bipath line 40 of the drum 20 to the condenser 30, a control valve 46 is equipped on a steam pipe 38, control valves 54, 56 are mounted on the pipe line 52 of the drum 20 to the overheater 22. The steam pressure at the inlet of a turbine 8 is controlled by the control valve 46. If load is decreased remarkably, the firm full admission control valve 54 is closed, the opening of a control valve 56 is decreased and the steam amount flowed into a steam turbine 26 is decreased keeping the opening of the control valve 46 constant. The control valve 42 ejects excessive amount of generated steam from the pipe line 40 to the condenser 30, controls the pressure of the drum 20 and can keep the gas of a boiler apparatus 14 at a constant temperature.
