Exergoeconomic analysis and performance assessment of selected gas turbine power plants

摘要: In this study, exergoeconomic analysis and performance evaluation of selected gas turbine power plants in Nigeria were carried out. The study was conducted using operating data obtained from the to determine exergy efficiency, destruction, unit cost electricity destruction major components a engine plants. results confirmed that combustion chamber is most destructive component compared other cycle as expected. total efficiency defects overall exergetic vary 38.64 69.33% 15.66 30.72% respectively. further shows improvement potential varies 54.04 MW 159.88 MW. with highest its value 30.21 88.86 show has greatest components. Increasing inlet temperature (GTIT), both found decrease. revealed an increase GTIT about 200 K can lead reduction 29% destruction. From costing analysis, produced cents 1.99 /kWh (N3.16 /kWh) 5.65 (N8.98 /kWh).
