摘要
从某城市电厂200 MW机组脱硝改造实际情况出发,结合电厂现有改造内外部条件与烟气情况,对脱硝剂选择、反应器布置方式与低氮燃烧器、省煤器、空预器及引风机改造等工程中遇到的主要问题进行了深入分析,并论证了改造措施的可行性,为同类型机组脱硝改造项目提供参考。
From the actual situation of 200 MW urban units denitrification transformation, combined with the existing condition of the internal and external conditions and gas conditions, analysis and demonstration are made in wiew of denitrification selection, the reac- tor layout, the low nitrogen burners modification, the economizer and air preheater transformation and induced draft fan transformation encounted in engineering. And discussions are made on the feasibility of the transformation measures. This article aims to provide ad- vices to power units denitrification transformation of the same type.
