PURPOSE:To increase the thermal efficiency of the overall plant by providing the secondary power generating facility having a steam turbine, a condenser, and a deaerator and a distrilling facility having a feed water heater cooling the steam to distill water. CONSTITUTION:The primary power generating facility 1 has a gas turbine 4 and a waste heat boiler 6. The secondary power generating facility 2 has a steam turbine 8, a condenser 10, and a deaerator 11. Part of the steam extracted from the steam turbine 8 is fed to the deaerator 11 and a steam generator 14 as a heat source. The steam evaporated from the steam generator 14 is fed to a feed water heater 15 and is cooled by the boiler feed water and is condensed into water. Accordingly, the boiler feed water is heated by the steam generated in the steam generator, thus the thermal efficiency of the overall plant can be increased. |
