摘　　要：应用热经济学方法,对涉及多个故障的串联能量系统进行了分析．既考虑了组元的“本质故障”对该组元(火用)耗系数增加的影响,又考虑了组元运行状态改变对该组元(火用)耗系数增加的影响,分析得出了导致组元(火用)耗系数增加的根源故障,进而结合“燃料影响公式”,推导给出了每个本质故障的燃耗影响的计算方法．Analyses a serial energy system with many malfunctions by the thermoeconomic method. Both intrinsic malfunction and operation situation change of components are considered for the increase of the unit exergy consumption. Derives malfunctions that cause the increase of the unit exergy consumption. Further, derives the method to calculate the fuel consumption impact of every intrinsic malfunction by the fuel impact formula.
