摘　　要：垃圾电站与常规电站主要区别在于锅炉与汽机侧汽水流程,蒸汽空预器汽水交换。汽机侧热耗率计算与锅炉效率计算边界条件的不统一,使基于锅炉反平衡的供电煤耗值失去了真实的意义。以某垃圾发电站为例,从供电煤耗计算方法入手,分析了计算结果产生差异的主要原因,为垃圾发电站节能诊断和挖掘节能潜力奠定了基础。The main difference between garbage power station and conventional power station lies in the flow of steam from boiler to turbine side and the exchange of steam from steam air preprocessor.The discrepancy between the calculation of steam side heat consumption rate and the calculation of boiler efficiency makes the coal consumption value based on boiler counterbalance power supply lose its real meaning.This paper starts with the calculation method of coal consumption for power supply and takes a garbage power station as an example to analyze the main reasons for the difference of calculation results,which lays a foundation for the diagnosis of energy saving of garbage power station and the exploitation of energy saving potential.
