Abstract: The heat recovery steam generator (HRSG) is an important and critical equipment of a combined cycle power plant that connects the gas turbine system to the steam cycle. The thermal design and the optimization of the HRSG are important for achieving safe operation, high efficiency and low product cost in a combined cycle power plant. This paper deals with the comprehensive optimization of the thermal design and minimization of the cost of an HRSG using a genetic algorithm (GA). Based on actual and existing designs of HRSG in most combined cycle power plants, a water tube HRSG including two superheaters, one evaporator and one economizer is considered in the optimization. A comprehensive program was developed in Visual Basic for this purpose.
