<p>PURPOSE:To effectively utilize energy by thermally recovering cooling water or burnt exhaust gas of a prime mover for driving a generator to be utilized as operating hot water for air conditioning, hot water supplying, drying, etc., and vaporizing the excess hot water to storage it in a steam accumulator. CONSTITUTION:Cooling water which cooled an oil pan 4 is passed through a water/water heat exchanger 5, hot water thermally exchanged by the water/ water heat exchanger 5 is heated by burnt exhaust gas to be discharged from the exhaust gas 8 of a prime mover 1, and temporarily stored in a hot water accumulator 9. The hot water from the hot water accumulator 9 is introduced into a preheater 12 arranged in an exhaust gas passage 8a to be heated. On one hand, the hot water from the preheater 12 is gradually heated by a steam generator 12 disposed in the exhaust gas passage 8 to be vaporized soon. This steam is stored in a steam accumulator 14, and fed as steam in response to necessity. On the other hand, the hot water from the preheater 12 is utilized as operating hot water for a room heater 15, absorption type refrigerators 16a, 16b, a hot water supply and dry apparatus 17, etc., and the thermally recovered low temperature water is again circulated to the water/water heat exchanger 5.</p> |
