摘　　要：为了减轻机组实时计算的负担,引入耗差系数。利用等效焓降方法建立数学模型,以130 MW循环流化床机组为实例,计算出一些重要参数在不同运行工况下的耗差系数,进而拟合出煤耗系数的变负荷特性曲线。结果表明各参数的煤耗系数具有变负荷特性。通过对煤耗系数变负荷特性的研究,对机组实时计算具有重要意义。In order to reduce the burden of real-time calculations, we introduced the concept of consumption deviation coefficient. The equivalent enthalpy drop method is used to build the mathematical models during analyzing the load characteristics of the consumption deviation coefficient for the 130 MW Circulating Fluidized power units. According to the result of the calculation, the curve fitting of some parameters under different operating conditions is drawn. Results show that, the consumption deviation coefficient is changed with load variation. The research of load characteristics of the consumption deviation coefficient plays an important role in the real-time calculations.
