Abstract: To recover the waste heat from bromine cooler of combined cooling, heat and power (CCHP) system, two solutions were put forward, to which calculation and analysis were carried out on the overall thermal utilization factor of primary energy consumption and the overall exergy efficiency. Results show that the energy utilization rates of both solutions are improved effectively; in the condition that the ratio of cold to steam (RCS) is relatively small, solution 1 with a simpler system is better than solution 2; in the condition that the RCS increases, both the overall thermal utilization factor of primary energy consumption and the overall exergy efficiency of solution 1 hardly change, while those of solution 2 increase first, decrease later on, which reach the maximum when the RCS is 3.3k.
