Exergy analysis of marine waste heat recovery CO2 closed-cycle gas turbine system

摘要: This paper presents an exergy analysis of marine waste heat recovery CO2 closed-cycle gas turbine system. Based on the operating parameters obtained in system exploitation, it is performed each component individually, as well whole observed While observing all exchangers found that combustion gases-CO2 have lowest destructions and highest efficiencies (higher than 92%). The efficiency detected Cooler (51.84%). Observed composed two turbines compressors. allows detection dominant mechanical power producer consumer. It also from much higher comparison to compressors (exergy both 94%, while did not exceed 87%). has destruction equal 6270.73 kW, 64.12% at selected ambient state. Useful produced by used for electrical generator drive equals 11204.80 kW. high proves its application on-board ships.
