摘要： PURPOSE:To enable to effectively utilize even the heat source, which is in the low temperature level of waste heat, and at the same time contrive to realize the heat storage in a small space and the miniaturization of transport pipes by a method wherein waste heat is recovered as pressurized hot water from the exhaust gas of an engine and the delivered air of a supercharger. CONSTITUTION:Feed water pressurized by a feed water pump 46 is heated into pressurized hot water at an air cooler 32 with the air delivered from a supercharger 33 and at a hot water generator 34 with the exhaust gas exhausted from the supercharger 33, while being controlled its flow rate with a temperature control valve 42 so as not to boil and to lower its temperature in response to the load of an engine 31. The pressurized hot water, the temperature of which is made constant, is accumulated in an accumulator 35 so as to be made its pressure also constant by controlling the water level in order to turn into saturated hot water. The saturated hot water is flashed in a multi-stage flasher 36 and the resultant steam is utilized at a turbine 37 and a heating service 41. The flasher drain of the final stage is sent to a drian tank 40 by means of a booster pump 45. Thus, the heat recovery at the temperature levels over wide range is made possible.
