摘要
从控制策略和测量方式两个方面进行研究,通过常规PID控制方法与常规PID+预测控制的控制方法的比较,以及单点取样测量与多点分区测量的比较,提出适用于新建及改造机组的SCR脱硝喷氨精准控制技术方案。
This paper studies control strategy and measurement method,through the comparison of conventional PID control and conventional PID+predictive control,and the comparison of singlepoint sampling measurement and multi-piont sampling measurement,an ammonia injection control scheme of SCR de-NOx system for new and modified units is proposed.
