چکیده انگلیسی
In power plant industry, it is always desirable that the performance of the plant should be as high as possible with the lowest possible investment. In this regard exergoeconomic analysis is a tool which combines thermodynamic analysis and economic principles to provide information that is helpful to predict thermodynamic performance and total cost of the plant. In this work an exergoeconomic approach is applied to the gas turbine based power plant cycles. In present work comparative exergoeconomic analysis of basic and reheat air-film blade cooled gas turbine cycles have been performed with exergy analysis as the basis. Average cost theory of exergoeconomic analysis has been carried out, in order to estimate the thermodynamic performance, thermoeconomics and electricity cost for power utility based on the cycle. Present work also represents the behavior of key parameters with cycle operating parameters (compressor pressure ratio and turbine inlet temperature) of proposed cycle. The comparative analysis result for base case (TIT = 1500 K, rpc = 26, ηAC=88%, ηGT=90%) being total cost rate = 20.172 $/h and 29.156 $/h, plant specific work = 422.49 kJ/kg and 576.40 kJ/kg and cost of electricity = 3.31 cents/kWh and 3.45 cents/kWh for basic and reheat gas turbine cycle based power utility respectively.
