HEAT-COLLECTING-TYPE POWER GENERATION SYSTEM |
摘要 |
Provided is a heat-collecting-type power generation system capable of maintaining a stable power generation efficiency even if supplied heat varies. The system includes an evaporator that heats and vaporizes a working medium; a displacement-type expander driven by the vaporized working medium; a power generator driven together with the expander; a condenser that cools and condenses the gas-phase working medium sent from the expander; and a circulation pump that draws the condensed liquid-phase working medium, raises pressure and transports the same to the evaporator, wherein the expander includes a plurality of expansion parts that expand the working medium stepwise, and internal volume ratios of the expansion parts are adjusted in a design phase, so that if at least one of a suction pressure and a discharge pressure of the expander varies, an overall thermal insulation efficiency is 70 percent or more, in a range of the variation. |
