Title:
SUPERCRITICAL FLUID POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/181663
Kind Code:
A1
Abstract:
Provided is a supercritical fluid power generation system that can achieve both high system efficiency and the suppression of an increase in equipment cost. The supercritical fluid power generation system (1) includes: a heat source (11); a turbine (31), a supercritical fluid power generation unit (30) provided with a turbine (31), a cooler (33), and a compressor (34) and using a closed cycle using supercritical carbon dioxide as a working fluid; and an intermediate heat medium circulation unit (50) that circulates a liquid molten salt that is heated by a high-temperature gas (13) heated by a heat source. The intermediate heat medium circulation unit includes a heat recovery heat exchanger (51) that exchanges heat between the hot gas and the molten salt, and an intermediate heat exchanger (52) that exchanges heat between the molten salt and supercritical carbon dioxide.
