To study the energy utilization of heat pump station for the recovery of waste heat of circulating water in the steam condenser of a coal-fired power plant,the primary energy ratio of the heat pump stations driven by different energy sources for the reclamation of waste heat was analyzed through energy flow diagram.The results show that the electric heat pump energy-supply system consumes 45.79% electricity although the total efficiency of electric heat pump energy-supply system is only 2% lower than that of heat pump energy-supply system driven by steam turbine,as well as approximately equals to that of system driven by gas turbine.Moreover,the situation maybe occurs that the electricity generated by power plant is not enough to its heat pump station with the decrease of the electric generation efficiency and COP of heat pump.By contrast,the primary energy ratio of the heat pump stations driven by steam turbine and gas turbine reaches 1.57 and 1.60,14.77% and 17.00% higher than that of electric heat pump station,respectively,because of introducing the primary energy exteriorly.Therefore,the heat pump stations driven by steam turbine and gas turbine are better than the electric heat pump station in energy utilization.
