本文针对大唐长春第三热电厂汽轮机在生产过程中,通过循环水排出大量低温余热的实际情况,采用热泵技术回收部分热量,实现冬季供暖.本文主要阐述了电厂循环水余热回收用热泵技术的原理,通过三种不同的供热方法介绍了加入热泵后充分回收废热,提高电厂热效率,扩大热电厂的供热面积.

In this paper,in connection with the actual situation of a large number of low temperature waste heat which is discharged with the recycled water in the steam turbine's production process at the three thermal power plant in Changchun.then we research some of the heat is recovered by the heat pump technology in 0r. der to achieve the winter heating program.The principle of the heat pump technology which is used in the waste heat recovery from the power plant circulating water is mainly explained,after adding heat pump then the waste heat is recycled fully,this all improve the power plant thermal efficiency,and the heating area is in- creased.
