PROBLEM TO BE SOLVED: To provide a power generating plant and its condensed water system facility in which a pig iron removing device is added, a work range accompanied by its additional construction is made minimum so as to reduce a work cost. SOLUTION: Water from a condenser 1 is supplied to either a boiler or a steam generator through a condensing pump 2, a gland steam condenser 3, a deaeration water level control valve 6, a low pressure water supplying heater 7, a deaeration unit 8 and a water supplying pump 9. A pig iron removing device 10, a pig iron removing device bypass line and a valve 13, opening or closing valves 20, 21, a jet pump driving pump 11 and a jet pump 12 are additionally installed at the water supplying system. Since a pressure loss is increased as the pig iron removing device 10 is additionally installed, a booster pump in the prior art is arranged, although not only the pump but also the pipings and the like are required for repairing in a large scale manner. Due to the presence of the additional installed portion D having the jet pump 12, the pipings across the portion D can be used as found in the prior art and so removal of pig iron can be carried out by a minimum repairing work.
