<P>PROBLEM TO BE SOLVED: To provide a temperature difference power generation apparatus capable of suppressing an equipment initial cost low by improving the efficiency of thermal energy and the output of power generation and miniaturizing an apparatus. <P>SOLUTION: An actuation medium 3 heated by a heat source fluid 1 is separated into a gaseous actuation medium 5 comprising a low boiling point component and a high-temperature solution 6 comprising a high boiling point component with a gas-liquid separator 4. In a thermal system which guides the actuation medium 5 to a power generator driving device 7 and rotates a power generator 8, the high-temperature solution 6 separated by the gas-liquid separator 4 is thermally exchanged with an actuation medium 13 on the low temperature side by a thermal recovery device 14, and thereafter, used for a driving source of an ejector 9. An actuation medium 5b exhausted by the power generator driving device 7 is mixed with the high-temperature solution 6 at an inner part of the ejector 9, and while the pressure is elevated, sent to a condenser 11. An actuation medium 10 sucked by a heat medium solution sending pump 12 is pressurized to become an actuation medium 13 and is led to an evaporator 2 through the thermal recovery device 14. Such a thermal cycle is repeated and energy held by the heat source fluid 1 is converted into electric power. <P>COPYRIGHT: (C)2013,JPO&INPIT |
