摘要： A cogeneration system is provided which includes a prime mover for obtaining power for driving a generator by combustion of a fuel, a waste heat boiler for recovering thermal energy from exhaust gas discharged from the prime mover, and a heat exchanger for heating air that is to be fed into an air conditioner by heat exchange with the exhaust gas discharged from the waste heat boiler. Drain water that is generated from the exhaust gas cooled by heat exchange in the air-heating heat exchanger (5) with the air that is to be fed into the air conditioner (30) is recovered by drain water recovery/supply means (36). The drain water recovery/supply means (36) supplies the drain water thus recovered to appliances (37, 38) that require comparatively high temperature water. Thermal energy can thus be recovered effectively from the drain water discharged from the heat exchanger on the downstream side of the waste heat boiler, thereby improving the efficiency of recovery of waste heat energy.
