The application of the exergy and exergoeconomic analysis for energy conversion systems is growing steadily. This analysis is particularly useful for energy conversion systems such as the combined-cycle power plant (CCPP). This paper deals with exergy and exergoeconomic analysis of a combined-cycle power plant with supplementary firing. A process simulation program, IPSE Pro, is used to model the combined-cycle power plant. Exergy and exergoeconomic analysis is carried out by developing a Matlab code. Three configurations of the combined-cycle power plant are investigated and the effect of the configurations of a heat recovery steam generator (HRSG) and performance parameters such as fuel mass flow rate of duct burner and pressure ratio of compressor on combined-cycle performance have been studied. Exergy and exergy cost destruction rates are also calculated. Finally, the cost of generated power for the three configurations of combined-cycle power plant is calculated and the best location for the duct burner in HRSG is proposed.
