摘　　要：利用蒸汽驱动吸收式热泵技术回收电厂循环水的余热供热技术已普遍推广,而且技术成熟。多数情况下,电厂提供的驱动蒸汽参数不同,不能满足热泵的正常工作要求。根据不同的蒸汽参数,提出相应的解决方案,最大限度地实现能量的梯级利用,并已成功应用于热电厂的余热回收工程中,供工程设计人员参考。It is very common to use the steam driven absorption heat pump technology to recover the waste heat of circulating water in power plants for urban heating projects,and the technology is becoming more and more mature.In many cases,the driving steam parameters provided by the power plant are different,which can not meet the normal working requirements of the heat pump.According to different steam parameters,provides corresponding solutions to maximize the cascade utilization of energy,and has been successfully applied to the waste heat recovery project of thermal power plant for engineering designers'reference.
