摘要
我国未对燃煤火电厂排放的NOx有效的控制,使其排放量随着装机容量增长而逐年增加,即将超越SO2成为第一气态污染物。针对目前严峻的形式,近年来脱硝技术成为烟气治理的重要研究方向。系统介绍低氮燃烧、干法、湿法等脱硝技术,探讨了其脱除过程及相关反应原理。
Our country hasn＇t made effective control of NOx emissions from coal-fired power plants, so that its emissions increase year by year with the installed capacity growth, and it＇s about to become the first gaseous contaminants beyond S02. Aiming at the serious form, in recent years the denifitration technology has become an important research direction of flue gas treatment. The paper summarized the incorporate technique of denitrification technology, including low NOx combustion, dry method, wet method and so on. The reaction process and theory among them having been given.
