چکیده انگلیسی:

Introduction: The major target of this paper shows effect of selected decision variables in the steam system foroptimization of thermal combined cycle power plant.Material and method: Exergoeconomic, and other similar terms used to imply the combined thermodynamicand economic analysis of energy systems, which helps to increase the efficiency of a plant without jeopardizingits economic viability. The optimization accomplished using an iterative exergoeconomic. The design data of anexisting plant (Damavand combined cycle power plant in Tehran) used for the present analysis.Results and Diction: Two different objective functions proposed: one minimizes the total cost of production perunit of output, and the other maximizes the total exergetic efficiency. The analysis shows that the total cost ofproduction per unit of output is 2% lower and exergy efficiency is 4% higher with respect to the base case. Itdemonstrates that selected decision variables have a good result for the exergy analysis and cost effectiveness
