摘要

根据优质优价原则

提出多联产能量系统产品单位火用流经济成本Ci与该火用流的能质因数iλ的关系为Ci=beiλ(简称能质因数法)

改进完善了多联产能量系统产品火用流经济成本分析的矩阵模式。通过实例

按能质因数法计算得到了多联产能量系统单位产品电与热的火用流经济成本

并与按产品等价得到的结果相比

表明根据能质因数确定单位产品火用流的经济成本比较适宜。

Abstract

According to the principle of "higher price for better quality"

the relationship between economic cost of product's unit exergy flow(Ci) in multiple co-generation system and energy quality factor of the said exergy flow(λi) has been put forward as in the following:Ci=beλi

it is called as "energy quality factor method" for short

improving and perfecting the matrix mode of economic cost analysis for product's unit exergy flow in the multiple co-generation system.Through practical examples

the economic cost of product's unit exergy flow in multiple co-generation system has been obtained by calculation according to the energy quality factor method

and a comparison with result obtained from the principle of "product equivalence" being made.It shows that the economic cost of product's unit exergy flow determined according to the energy quality factor is more appropriate.
