火电厂“超洁净排放”改造策略研究

Research on reformation strategy of thermal power plant for “untra clean emissions”

随着环保减排政策的不断收紧,火电企业进行"超洁净排放"改造势在必行。介绍了实现"超洁净排放"改造的可行性技术措施,包括脱硝方面的低氮燃烧技术和低负荷投运改造方案、脱硫方面的增容改造方案和单塔双循环技术、除尘方面的湿式电除尘技术和高频电源技术。最后,对火电企业今后面临的热点问题进行了展望。

Along with the environmental policy becoming more and more rigorous,the reformation of ultra clean emission in thermal power enterprises is imperative. The feasible technical measures to realize ultra clean emission reformation were introduced as below. In denitration,there are low NOxcombustion technology and the low load putting into operation reform scheme. In desulphurization,there are the reformation of capacity extansion and the single tower duoble circulation technology.In dust removal,there are wet electrical dust removal technology and high frequency power supply technology. At last,the hot topics of thermal power enterprises in future were prospected.
