Large thermal power units have a large amount of low-grade waste heat,and how to achieve efficient utiliza-tion of low-grade waste heat is particularly crucial.This paper proposes a waste heat utilization scheme based on absorp-tion heat pumps to address the problem of recycling waste heat utilization in thermal power units.The performance of ab-sorption heat pumps during the waste heat utilization process is systematically analyzed.The results show that the higher the pressure of the driving heat source,the higher the temperature of the low-temperature circulating water,the lower the return water temperature of the heating network,and the larger the COP value of the heat pump unit,and the better the overall economic performance of the unit.
