A supercritical CO2 generation system including a compressor configured to compress a working fluid; a first heat exchanger that exchanges heat with the working fluid passing through the compressor; a high temperature turbine that expands the working fluid passing through the first heat exchanger and connects to a power generator to produce power; a second heat exchanger that exchanges heat with the working fluid passing through the compressor; a low temperature turbine that expand the working fluid passing through the second heat exchanger and connects to the power generator to produce power; a third heat exchanger between the first heat exchanger and the high temperature turbine that exchanges heat with the working fluid recuperated by the first heat exchanger; and a cooler that cools the working fluid passing through the high temperature turbine and the low temperature turbine and supplies the cooled working fluid to the compressor.

Supercritical CO2 generation system

A hybrid power generation system using a supercritical COcycle includes a steam power generation unit including a plurality of turbines driven with steam heated using heat generated by a boiler to produce electric power, and a supercritical COpower generation unit including an S&#x2014;COheater for heating a supercritical COfluid, a turbine driven by the supercritical COfluid, a precooler for lowering a temperature of the supercritical COfluid passing through the turbine, and a main compressor for pressurizing the supercritical COfluid, so as to produce electric power. The steam power generation unit and the supercritical COpower generation unit share the boiler. The hybrid power generation system may improve both the power generation efficiencies of the steam cycle and the supercritical COcycle by interconnecting the steam cycle and the supercritical COcycle.
