摘　　要：化工热能动力多联产系统的特点为多能源输入、多产品输出,传统的热力学性能指标,主要为热效率、相对节能率、效率、经济效率、经济系数以及能量综合梯级利用率等,单独作为系统设计的优化的主要目标函数并不科学。本文将能源-环境-经济(3E)综合评价法用于评价煤化工热能动力多联产系统,更贴近实际运行情况。The characteristics about co-generation system of coal chemical industry are multi-energy input and multi-energy output; Traditional thermodynamic performance indicators mainly refer to thermal efficiency, relative energy-saving rate, exergy efficiency, economic exergy efficiency, economic exergy coefficient and the rate of energy cascade utilization etc. Obviously, it is no sence that they are used separately as objective function of system design and optimization. The article uses Energy-environment-economy （3E） comprehensive evaluation method to analyse co-generation system of coal chemical industry and thermal power integration. It is more relistic to the actual operation case.
