SUPERCRITICAL CO2 GENERATION SYSTEM

摘要

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.

1. A supercritical CO2 generation system, comprising:
a compressor configured to compress a working fluid; a first heat exchanger configured to exchange heat with the working fluid passing through the compressor; a high temperature turbine configured to expand the working fluid passing through the first heat exchanger and to be connected to a power generator to produce power; a second heat exchanger configured to exchange heat with the working fluid passing through the compressor; a low temperature turbine configured to expand the working fluid passing through the second heat exchanger and to be connected to the power generator to produce power, wherein a temperature of the high temperature turbine is higher than a temperature of the low temperature turbine; a third heat exchanger configured to be provided between the first heat exchanger and the high temperature turbine to exchange heat with the working fluid recuperated by the first heat exchanger; and a cooler configured to cool the working fluid passing through the high temperature turbine and the low temperature turbine and supply the cooled working fluid to the compressor.
