摘要
对燃煤电厂的尾部烟气进行脱氮处理可大量减少氮氧化物的排放,显著改善环境。选择性催化还原(SCR)脱氮技术是一种用于脱除燃料燃烧后烟气中所含氮氧化物的技术。介绍SCR脱氮技术的基本原理、系统组成及加装SCR装置对空气预热器和引风机等相关辅机的设计和材料选型等方面造成的影响,并给出相应的建议。
To conduct deNOx treatment of flue gas in coal-fired power plant may greatly reduce the NOx emission, obvionsly improve the environment. The selective catalytic reduction (SCR)deNOx technology is a technology to remove the NOx in fluegas after the fuel is burned. This paper briefs the basic principle,system configuration of SCR and the impacts of newly-added SCR eguipment on the design and material selection of air preheater and induced draft fan etc.relevant auxiliary eguipment, and puts forward the corres ponding suggestions.
