LEAKED CARBON DIOXIDE REINJECTION SYSTEM FOR SUPERCRITICAL CARBON DIOXIDE POWER GENERATION APPARATUS

摘要

According to the present invention, easy reinjection of leaked carbon dioxide is possible by capturing carbon dioxide leaking from a turbine of a supercritical carbon dioxide power generation apparatus, consecutively elevating the pressure of the captured carbon dioxide with a compressor and an ejector, and reinjecting the carbon dioxide. In addition, a compressor and an ejector are used together to minimize the power consumption of the compressor, thereby improving the efficiency thereof. Further, there is the advantageous of easily elevating the pressure of carbon dioxide in the ejector because a part of carbon dioxide in a high pressure condition before suction into the turbine is suctioned as a primary flow into the ejector.
