摘要

通过对能源系统增加虚拟排放治理单元，以排放火用小成本和火用小经济学成本的形式量化终端排放的环境影响，从而来统一产品输出相同、终端排放不同的系统间热力、环境和经济(TEE)性能比较基准；其次，把排放火用小成本和火用小经济学成本按照各单元排放占联产系统终端排放的比例分摊，来考虑联产系统不同产品对应环境影响的差异，建立了一种适合联产系统的环境火用小经济学综合评价分析方法；最后，以煤气化F-T合成燃料/电联产系统为例介绍该方法应用。与常规基于热力学第一定律的技术经济方法分析结果对比表明：该方法能够以环境火用小成本的形式分析联产系统的产品能耗、成本和TEE综合效益来源。与常规火用小经济学方法分析结果对比表明：该方法可以体现联产系统终端排放对不同产品的影响差异以及联产系统TEE综合性能潜力。

Abstract

A comprehensive evaluation method of thermal

environmental and economic (TEE)performance for an energy system with multi-products was proposed.In this approach

environmental impact of the energy system was quantified in form of exergy cost of the virtual emission treatment unit

which was a virtual unit and had no effect on energy system itself.Then

exergy cost of virtual emission treatment unit was distributed to each unit of energy system to reflect the difference of influences of environmental concern on different products

according to the proportion of emission produced by each unit in the total emission of energy system.And then

in order to introduce application of this comprehensive evaluation approach

a coal gasification Fischer-Tropsch synthesis and electricity co-production system was analyzed.Compared with that by the conventional technical and economic approach based on the first law of thermodynamics

the proposed approach could be used to calculate the energy consumptions and costs of different products

and analyze the benefit sources of comprehensive TEE performance of the co-production system.Compared with that by the conventional exergy-economic analysis method

the proposed approach could reflect the difference of influences of environmental concern on different products

and the comprehensive TEE performance potential of the co-production system.
