Both Exergy and Pinch Analysis have been studied and applied effectively to energy system separately for many years. Exergy analysis is widely used in energy system analysis for more efficient energy use. Pinch technology has focused on the one energy systems, especially chemical plants, which usually are pure heat exchanger networks. In this study, the objective is to seek more effective meilns for integrating two methods, with taking advantage of both. In order to demonstrate effective result and to prove possibility for pinch analysis to apply power system , applying exergy to composite and grand composite curve, we study the optimal integration of heat exchanger network with power generation and heat pump. also. We chose phosphoric acid fuel cell cogeneration with waste heat recovery unit. As the results, this study makes more or less the reduction of number of heat exchangers and improvement on 2nd law efficiency through the entire system.
