汽动给水泵乏汽吸收式热泵机组试验研究及经济性分析

摘要

This paper elaborates the working principle of the absorption heat pump and its application on waste heat recovery project. The back pressure of steam feed pump was increased by applying heat pump,and the effect of the heat pump on waste heat recovering performance was analysed. Consequently,the heat pump energy efficiency ratio with load change was drawn and the variable relations of heat absorbing was obtained,besides,its economic analysis was carried out,which is instructive for other power plants in terms of waste heat recovery.%阐述了吸收式热泵的工作原理，及其在电厂乏汽余热回收工程中的应用。通过热泵投运增加汽动给水泵的背压来分析其对热泵余热回收性能的影响，得出热泵随负荷变化的能效比及热泵吸收热量的变化关系，并对其进行经济性分析，为今后电厂乏汽回收利用提供指导作用。
