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 operated by a working fluid supplied thereto, the working fluid being heated by heat generated in the furnace;
- a recuperator that exchanges heat with the working fluid passing through the turbine;
- 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, and
- the working fluid is supercritical CO2.

A CO2 power generation system, comprising:
- a turbine that is operated by a working fluid;
- a recuperator that exchanges heat with the working fluid passing through the turbine;
- a cooler that cools the working fluid passing through the recuperator;
- a first compressor that compresses the working fluid passing through the cooler;
- a second compressor that compresses a portion of the working fluid passing through the recuperator;
- and
- a furnace into which the working fluid passing through the first and second compressors is introduced to be heated by combustion heat, wherein
- the working fluid is circulated to the turbine via the furnace, and
- the working fluid is supercritical CO2.
