摘　　要： 在火用分析及火用经济分析的基础上，说明了排弃火用与待回收火用的关系，就不同的回收情况，系统地研究了能量系统中排弃火用的计价问题；指出对于能量的逐级回收利用，传统的按物流的序贯分析计价方法并不适用于排弃火用的计价，基于能量系统双子系统模型，提出了当量计价的概念以解决排弃火用的计价问题。最后以催化裂化烟气能量回收方案的演变过程及排弃火用计价的变化表明了此计价方法的实际应用情况。 Based on an analysis of exergy and its economic aspects the authors expound the relationship between rejected exergy and the exergy to be recovered. After an systematic study of the rejected exergy costing in an energy system under various conditions of recovery it is pointed out that with respect to the stage by stage recovery and utilization of energy the traditional costing method in accordance with a material flow sequential analysis is not applicable to the costing of rejected exergy. On the basis of an energy system dual sub system model proposed is an equivalent costing conception aimed at solving the problem of rejected exergy costing. Finally, the practical application of this costing method has been demonstrated through the evolution process of a catalytic cracking gas energy recovery scheme and the variation of rejected exergy costing.
