Abstract:  
The present work is an attempt to investigate the advanced exergy analysis of cogeneration power plant based on gas turbines and ORC. To this end, the ORC, with internal heat exchanger and R123 as working fluid, is coupled to GT cycle by means of Heat Recovery Steam Generator. Comparing the results of cogeneration based on GT with those of cogeneration based on GT-ORC shows that the magnitude of net power has increased from 30MW to 30.73 MW. Also, the maximum endogenous exergy destruction in the GT-ORC based cogeneration system has occurred in the combustion chamber, HRSG and GT, respectively. The HRSG is the next component to combustion chamber which has improved in the conventional exergy analysis, while the air pre-heater is the second component which improves in the advanced exergy analysis.
