Zusammenfassung:	PURPOSE:To obtain high heat recovering efficiency by the minimum heating surface area of a boiler, by a method wherein high temperature water from the boiler is sent to the upper part of an accumulator and low temperature water to be stored in the accumulator is returned to the boiler for reheating. CONSTITUTION:A waste heat recovering turbine generating system consists of a boiler system formed by connecting a feed water pump 3 and an accumulator 14 with a waste heat boiler 1 and a turbine system including the accumulator 14 and a steam turbine 5. A throttle control valve 16 controls the temperature of hot water at an outlet of the boiler 1 so that it becomes a saturation temperature at the highest pressure of the accumulator 14 and high temperature water is sent to the upper part of the accumulator 14 for constant pressure heat accumulation. A low temperature water whose temperature is lower than a saturated temperature storable within the accumulator is returned to the boiler 1 through a valve 19 for reheating. In this manner, wasted heat can be recovered highly efficiently by making use of a heating surface area.
