ABSTRACT:
A feed water supply pump and a second control valve are provided in a water supply line system and a first control valve is provided at a second steam line. Further, a third control valve is provided at a hot water supply line. In this manner, the terminal temperature difference between the circulating water and the exhaust gas at the inlet and outlet of a preheating portion of an exhaust gas economizer are so controlled as to become equal. In addition, steam discharged from an exhaust outlet of a multi-pressure steam turbine is turned to water by means of a condenser and then, the condensed water is returned to a drain tank while withdrawing and collecting heat energy respectively in a lubricating oil cooler, a fresh water cooler and an air cooler of an internal combustion engine.
