Thermoeconomic and thermoenvironomic modeling and analysis of selected gas turbine power plants in Nigeria

摘要: This study presents comprehensive thermoeconomic and thermoenvironomic modeling analysis of selected gas turbine power plants in Nigeria using the first second laws thermodynamics (exergy) concept. Exergetic analysis was conducted operating data obtained from the to determine the exergy destruction efficiency each major component the gas plant. The results showed that combustion chamber (CC) is most destructive compared to other cycle components. percentage CC varies between 86.05% 94.6%. By increasing inlet temperature (GTIT), the this can be reduced. total improvement potential 54.04 159.88 MW. The component with highest improvement potential CC, which has the value 30.21 88.86 Thermoeconomic showed that cost high an increase the GTIT effectively decreases cost. costing revealed the unit electricity produced ranged cents 1.99/kWh (N3.16/ kWh) 5.65 /kWh (N8.98/kWh). Thermoenvironomic CO2 emissions varied between 100.18 408.78 kg CO2/MWh, while cost rate environmental impact 40.18 $/h (6, 388.62 N/h) to 276.97 (44, 038. 23 N/h). further emissions and decrease GTIT. sustainability index Finally, will assist efforts to understand thermodynamic losses cycle, improve efficiency as well provide future recommendations for better performance, sustainability, lessening
