Abstract
A CO2 power generation system includes a furnace to burn fuel, a turbine operated by a working fluid supplied thereto, the working fluid being heated by heat generated in the furnace, a recuperator exchanging heat with the working fluid passing through the turbine, a cooler to cool the working fluid passing through the recuperator, and a compressor to compress the working fluid passing through the cooler, wherein the working fluid passing through the compressor is circulated to the furnace, and the working fluid is supercritical CO2.
Claims20
A CO2 power generation system, comprising:
- a furnace that burns fuel;
- a turbine that is supplied with a working fluid of supercritical CO2 heated by heat generated in the furnace;
- a recuperator that exchanges heat with the working fluid passing through the turbine;
- a first separator provided at a rear of the turbine so as to branch the working fluid passing through the turbine into the recuperator and the furnace;
- a cooler that cools the working fluid passing through the recuperator;
- and
- a compressor that compresses the working fluid passing through the cooler,
- wherein the working fluid passing through the compressor is circulated to the furnace.
