英文摘要: Abstract(#br)This paper deals with an advanced exergy analysis and optimization of a real CCPP (combined cycle power plant) with DBs (duct burners) located in Iran. The endogenous/exogenous exergy destruction parts of each component as well as their combinations with avoidable/unavoidable parts are determined. A parametric study is carried out to assess the sensitivity of total avoidable exergy destruction and CO 2 emission to TIT (turbine inlet temperature), compressor pressure ratio (r c ) and DB fuel mass flow rate ( m ˙ DB ). Parametric results reveal that the increments in TIT and r c improve the CO 2 emissions by about 6.8% and 17%, respectively and the total avoidable exergy destruction rate increases within 19% when r c is in the range of 9–14. In addition, NSGA-II...
