Abstract
The present study deals with an Analysis of power generation systems are of scientific interest and also essential for the efficient utilization of energy resources. The most commonly-used method for analysis of an energy-conversion process is the first law of thermodynamics. Therefore, the effect of key parameters on the out put power and efficiency are so important. In this paper, the effects of key parameters in both firs law and second law of thermodynamics point of view have performed. It was intended to determine unfavorable points from exergy destruction concept using exergy analysis for steam power plants cycle. Also, variation in efficiency and exergy destruction is evaluated using variations of temperature of high pressure steam, temperature of reheat, and condenser pressure. The study of the effect of feed-water heaters shows that increase in number of heaters up to 3 causes increase in both first and second low efficiency, but further increase has the reverse effect. The results show that boiler has the greatest exergy destruction among the power plant components.
