摘要

为了应对大气污染物排放问题

燃煤电厂正逐步实施超低排放改造。本文论述了燃煤电厂超低排放改造关键点

包括边界条件、运行现状、脱硝改造方案、除尘改造方案、脱硫改造方案和风机改造方案等

阐述了燃煤电厂超低排放改造的主要技术路线

统计分析了其在已实施项目中的应用情况

以及超低排放改造的投资成本、运行成本、经济效益和环境效益。分析结果表明:超低排放改造技术路线的选取与投资成本间不存在明显规律

技术路线的选取应结合机组实际情况

综合比较其技术经济性后确定;燃煤品质越好

机组容量越大

超低排放改造的单位投资成本越低

经济和环境效益越显著。

Abstract

In order to deal with the problem of air pollutant emission

coal-fired power plants are pushing on ultra-low emission reform. The key points of ultra-low emission reform in coal-fired power plants are discussed

including boundary condition

operation status

denitration transformation scheme

dust removal transformation scheme

desulphurization transformation scheme and fans transformation scheme. Main technical routes for ultra-low emission transformation for coal-fired power plants are introduced. Moreover

the application of main technical routes in current power plants are analyzed. The investment cost

operation cost

economic benefit and environmental benefit of ultra-low emission are analyzed. The results show that

there is no obvious rule between ultra-low emission reform technical routes and investment cost. Before formulating technical routes

technology and economy of the projects should be compared according to the actual situation of units. Better quality of coal and larger unit capacity will lower the unit investment cost of ultra-low emission reform and improve the economic and environmental benefits.
