Abstract

Due to the importance of power generation cycles including combined cycle, many studies have been done in recent years and many researchers have been tried to optimize these cycles by using of existing methods. In this study, the Water-Ammonia cycle is investigated in the combined-cycle of the Water-Ammonia, working dual Water-Ammonia mixture is used as the works fluid. This cycle can be used from different sources such as typical power dissipation of energy cycles or independent heat source that used from solar energy or geothermal.
The aim of this paper is the investigation of the inlet temperature on thermodynamic performance of the Water-Ammonia combined cycle. In this research, at first, the Ammonia-Water cycle can be modeled with by using of EES software and then the Rankine-thermodynamic gas combined cycle is simulated. Also, the results are studied from the perspective of the first and second law of thermodynamics. Finally, the effect of turbine inlet temperature into the thermodynamic performance is discussed.
