ABSTRACT
In this paper, through conventional exergy-based analysis are definitely the components with highest irreversibilities. To overcome limitations of the conventional exergy analysis and to increase our information about how and what extent the cogeneration system component can be improved, advanced exergetic analysis is conducted. At the same time, the method for calculating the avoidable and unavoidable exergy destruction for a similar class cogeneration system is proposed. Moreover, the criterions assist in identifying the real potential of improving of the kth plant components are calculated in present study. Therefore, this paper provides addition information about realistic potential for improving the thermodynamic efficiency of the cogeneration system component and approves the advanced exergetic analysis as a reasonable step in the development of the thermodynamic model of considered cogeneration system.
