Theoretical performance analysis on DH Economizer in Hwasung CHP was conducted. At first, current operating conditons and logics were examined, and two methods to improve the heat exchange performance were reviewed. One is to change the contorl logic, and the other is to increase heat exchanger capacity. ɛ-NTU analysis was performed to verify the feasibility of two methods. It was found that both methods are effective way to increase heat recovery of DH Economizer in Hwasung CHP.
