摘要

以太原市生活垃圾焚烧发电厂为例

运用热经济学结构理论

对电厂各组元的单位热经济学成本、成本差和火用经济系数等指标进行了计算分析。结果表明

发电系统中的用能薄弱环节主要在余热锅炉与垃圾焚烧炉

原因在于其火用损、垃圾处理成本高带来的燃料单价与非能量费用均偏高;用于垃圾焚烧发电系统的设备成套性较差

产生了给水泵、凝结水泵等设备非能量费用高的问题。

Abstract

Taking the municipal solid waste (MSW) incineration power-generating system in Taiyuan City as an example

the indices of each component in the plant

such as unit thermo-economic cost

cost difference

and exergy economic coefficient

etc. have been calculated and analysed by using the structural theory of thermo-economics. Results show that the vulnerable spots in energy utilization mainly to be the heat recovery boiler and the MSW incinerator

the causes are high unit price of fuel and high non-energy expenditure due to high exergy loss and high cost of MSW handling

besides

the equipments used for MSW incineration power-generating system can’t perfectly form a complete set

leading to higher non-energy expenditure of the feed-water pump and the condensate pump.
