<P>PROBLEM TO BE SOLVED: To improve heat efficiency of a power generation apparatus by further using a medium used for cooling a circulation pump, for heating. <P>SOLUTION: The power generation system 1A includes: an evaporator 2 generating vapor of a working medium T by evaporating the working medium T discharged from the circulation pump 6; a power generator 3 generating power by using expansion of the vapor generated in the evaporator 2; a condenser 4 condensing the vapor used in the power generator 3 to the liquid working medium T; and the circulation pump 6 forcibly feeding the liquid working medium T obtained in the condenser 4 to the evaporator 2 and circulating the working fluid T. The circulation pump 6 is configured to include an electric motor driving the circulation pump 6, use a part of the supplied liquid working medium T for cooling the motor, then discharge it to the outside as a heating medium, and forcibly feeding the working fluid T other than the heating medium to the evaporator 2. A heating medium line 12 is provided which enables heat exchange with the heating medium discharged from the circulation pump 6 and leads the heating medium after heat exchange to the condenser 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
