摘　　要：在火电厂运行机组的热经济指标的分析计算中,以等效焓降为基础提出等效凝汽焓降和等效凝汽系数的概念并将其用于再热机组的计算中,通过一个算例说明该方法有准确、物理概念清楚、便于计算的特点。From the view of construction of calculate model and the exact index, this paper try to find a improved method in thermal ecomomical performance cacaulation for coal-frie power plant. Numberial examples show that the meathod has the characteristic of accurate, clear of physical meaning, convenient to calculation.
