Title:
HEAT RECOVERY POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2015096703
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a heat recovery power generation system which can return cooling water at a temperature appropriate to reliability of an engine to the engine while performing heat recovery from the cooling water to the maximum.SOLUTION: A heat recovery power generation system 1 comprises: a cooling water circulation flow passage 16 through which cooling water W for cooling a water-cooling jacket 15 circulates; an exhaust gas flow passage 12 for exhausting exhaust gas G of a diesel engine 11; a heat medium circulation flow passage 21 where a heat medium M circulates through a closed loop formed by a low temperature side evaporator 5 performing heat exchange between the cooling water W and the heat medium M and evaporating the heat medium M, an expander 23 expanding the heat medium M evaporated by the low temperature side evaporator 5 and obtaining rotation driving force and a condenser 8 liquefying the heat medium M caused to be a low pressure vapor phase in the expander 23; a generator 25 receiving the rotation driving force obtained by the expander 23 and performing power generation; and a high/low heat exchange 7 performing heat exchange between the exhaust gas G flowing through the exhaust gas flow passage 12 and the cooling water W flowing through the cooling water circulation flow passage 16.
