Abstract

PURPOSE:To increase the thermal efficiency of a plant by varying the pressure of the steam jet system according to the necessary pressure of a gas turbine and allowing surplus steam to be generaged as much as possible in partial loading. CONSTITUTION:The saturated steam 5 from a steam boiler 2 is flow-amount-controlled by a steam flow-amount-controlling valve 15 for steam injection for a gas turbine 10 and injected into a combustor 12 and utilized for reducting Nox discharged from the gas turbine 10. The pressure is set at 18 atmospheric pressure by a pressure controller 51 in the rated loading of the gas turbine 10, and this prescribed value is varied according to the load of the gas turbine 10. The surplus steam generated in partial loading is flowed into a deaerator 34 by the opening of a flow- rate controlling valve 53 due to the pressure controller 51 and by a low-pressure heater 33 and a condenser 32.
