摘要：Heat recovery steam generator (HRSG) plays a key role on performance of combined cycle (CC). In thiswork, attention was focused on a dual pressure reheat (DPRH) HRSG to maximize the heat recovery and henceperformance of CC. Deaerator, an essential open feed water heater in steam bottoming cycle was located to enhance theefficiency and remove the dissolved gasses in feedwater. Each of the heating section in HRSG is solved from the localflue gas condition with an aim of getting minimum possible temperature difference. For high performance, betterconditions for compressor, HRSG sections, steam reheater and deaerator are developed. The CC system is optimized ata gas turbine inlet temperature of 1400◦C due to the present available technology of modern gas turbine blade coolingsystems. The exergetic losses in CC system are compared with each other. The present DPRH HRSG model has beencompared and validated with the plant and published data.
