چکیده انگلیسی
The exergoeconomic and exergoenvironmental analysis of cogenerative system that combine a gas/steam turbine system and a solar field have been performed. The model is developed in order to produce around 400Â MW of electrical power to investigate the effect of solar collector field in performance of each component. In addition, the exergy destruction, exergetic efficiency, cost rate and environmental impact per exergy unit, cost rate and environmental impact per exergy unit of product and fuel, cost rate and environmental impact rate associated with the exergy destruction, exergoeconomic and exergoenvironmental factor for each component are evaluated. The results reveal that the condenser needs to increase investment costs to increase the total thermodynamic efficiency and it needs to increase its exergetic efficiency to reduce the total environmental impact from an exergoeconomic and exergoenvironmental point of view. The exergoeconomic and exergoenvironmental analysis show that the effects of solar field leads to 4.2% increasing in the net produced electricity; 2.6% increasing in the average cost rate per exergy unit of electricity and â3.8% decreasing average environmental impact per exergy unit of electricity.
