摘　　要：利用吸收式热泵回收电厂循环水余热,能够提高机组的热效率和供热能力,降低机组的冷源损失。以某300MW供热机组为例,确定两种计算方案,对抽汽供热与循环水吸收式热泵供热的联产机组经济性进行对比分析。计算结果表明:利用热泵回收电厂循环水余热具有良好的社会效益和经济效益。Heat recovery of circulating water in power plant by absorption heat pump can improve the thermal efficiency of the unit and heat supply capacity, and reduce the cooling source loss. In a 300 MW steam turbine as an example ,to determine the two computational scheme, pumping steam heating and circulating water absorption heat pump heating cogeneration unit economy were analyzed. The results show that the use of heat pump to recover the waste heat of circulating water in power plant has good social and economic benefits.
