摘要:
本文对国内12个具有代表性的燃煤电厂进行了实地调研,在此基础上,建立了包括环境、技术、经济3个方面的多因素多层次的综合评价指标体系,并且运用灰色层次分析法对当前火电行业采用的空气分级燃烧技术、燃料分级燃烧技术、烟气再循环技术、低氮燃烧器技术、SNCR、SCR和SNCR-SCR共7种主流氮氧化物控制技术进行了环境、经济、技术三个方面的综合评价,得出7种主流氮氧化物控制技术的优劣顺序为:SCR、低氮燃烧器技术、空气分级燃烧技术、烟气再循环技术、燃料分级燃烧技术、SNCR-SCR、SNCR。

Abstract: 12 typical coal-fired power plants in China were researched in this paper. A multi-level assessment index system of nitrogen oxide control technologies was established in consideration of en-vironmental performance, economic performance and technical performance. Then, seven kinds of mainstream nitrogen oxide control technologies including air staged combustion technology, fuel staging combustion technology, flue gas recirculation technology, low NOx burner, selective non-catalyst reduction (SNCR), selective catalyst reduction (SCR) and hybrid SNCR/SCR (SNCR-SCR) were evaluated comprehensively by making use of grey multi-hierarchy comprehensive evaluation method. According to the result, the prior sequence of these seven kinds of nitrogen oxide control technologies was got in turn: selective catalyst reduction (SCR), low NOx burner, air staged combustion technology, flue gas recirculation technology, fuel staging combustion technology, SNCR-SCR and SNCR.
