HYBRID POWER GENERATION SYSTEM USING SUPERCRITICAL CO2 CYCLE

摘要

Disclosed herein is a hybrid power generation system using a supercritical CO2 cycle, which includes a first working fluid circuit configured to produce electric power by a first working fluid heated in a boiler, and a second working fluid circuit configured to produce electric power by a second working fluid, and the first and second working fluid circuits share the boiler. The hybrid power generation system can remove an air preheater of a thermal power generation system and separate heat exchange units for exhaust gas and air after combustion, so as to utilize the heat exchange units as a heat source and a cooling source in a supercritical CO2 cycle. Consequently, it is possible to improve power generation efficiency by recovering the leakage loss of the air preheater.
