SUPERCRITICAL CARBON DIOXIDE POWDER PLANT

摘要

The present invention relates to a supercritical carbon dioxide power generation system. More specifically, the supercritical carbon dioxide power generation system comprises: a regenerator to heat supercritical carbon dioxide; a turbine to use the supercritical carbon dioxide heated by the regenerator to operate; a heat collector to collect heat of the supercritical carbon dioxide flowing out of the turbine to heat the supercritical carbon dioxide flowing into the regenerator; a condenser to condense the supercritical carbon dioxide which has passed through the heat collector; a compressor to compress carbon dioxide flowing out of the condenser; an expansion valve to expand at least a portion of the carbon dioxide flowing out of the condenser; a flash tank to separate the expanded carbon dioxide into liquid and gas; a heat exchanger disposed between the condenser and the compressor, in which the separated gas and at least a portion of the carbon dioxide flowing out of the condenser exchange heat; and an ejector to collect the separated gas which has passed through the heat exchanger to move the gas to the condenser. The supercritical carbon dioxide power generation system according to the present invention can increase efficiency of a cycle of supercritical carbon dioxide and utilize waste heat of a power generation system.
