PURPOSE:To utilize surplus steam to extract the power and save the commercial power quantity by providing an operating fluid evaporator at the upstream side of a gas passage to drive a turbine and providing a cooling cycle to reuse the evaporated operating fluid gas. CONSTITUTION:As a plant is gradually transferred to a normal operation, the steam in a boiler 2 is fed to a producer 1, and the generated quantity of high- temperature pressure gas is gradually increased, the driving force of turbines 12, 16 is increased. Therefore, if the quantity of surplus steam directly fed to a gas passage 3 is decreased, the processed steam is almost used as the drive source of the turbine 12 and is recovered as the electric power. During a normal operation, the used quantity of surplus steam is further decreased and processed gas is much used, thereby the power quantity generated by the turbines 12, 16 is increased. Accordingly, the used quantity of the commercial power is reduced, and if the pressure control of the commercial power is reduced, and if the pressure control of the processed gas is simultaneously performed, gas expansion occurs in the turbine 16, and gas cooling and dehydration can be performed. |
