Abstract :

In addition, to optimally find the optimum design parameters, an exergoeconomic approach with multi-objective function is employed. The demanded power on the fixed design parameter is 360 MW of net power output. The results show that exergy efficiency and cost product for plant are 8% and 3% better than base case, respectively. Since, environmental pollution and energy shortage are the two factors limiting the development of the society; nevertheless, this analysis tends to optimally find the design parameters which result in a decrease in the fuel mass flow rate. Also, this reduction (about 6.4%) in the mass flow rate and increasing exergetic efficiency can decrease the environmental impacts. Finally, the analysis and comparison between the results of the current research and two other researches was done and the results are reported.
