SUPERCRITICAL CARBON DIOXIDE POWER GENERATION SYSTEM

摘要

The present invention relates to a supercritical carbon dioxide power generation system which comprises: a combustion unit generating a first mixture having supercritical carbon dioxide by burning methane using air for combustion; a turbine unit generating power to operate a generator by using the first mixture having supercritical carbon dioxide discharged from the combustion unit for the generator to produce electricity; a first separation unit separating the first mixture to a gaseous state of a second mixture and a liquid state of water after liquefying steam of the first mixture discharged from the turbine unit; and a second separation unit separating the second mixture to a liquid state of carbon dioxide and a gaseous state of nitrogen after liquefying carbon dioxide of the second mixture discharged from the first separation unit.
