摘要
随着空气质量的日益恶劣和全民环保意识的逐渐增强,社会对排放氮氧化物占70%以上的燃煤电站的要求越来越高,但是在中国脱硝技术的实际应用刚开始,相应的过程控制系统有待在前进过程中不断调整与完善。本文以已经投入脱硝系统使用的国华沧东电厂为例,介绍SCR法烟气脱硝系统的控制策略。
With the deterioration of the air quality and the increasing of the environmental awareness of the whole people,the society has higher and higher requirement on the coal-fired power stations which discharge nitrogen oxides account for more than 70%,but practical application on denitrification technolog is still young in china,process control system that goes with it calls for continuous adjustments and perfection on the way to advance.To take Cang Dong power plant that denitrification system are being used in for an example,This article presents the control strategy of SCR flue gas denitrification.
