摘　　要：燃煤电厂SCR脱硝系统中普遍存在氨逃逸率高的问题,为解决氨逃逸率高的问题,必须对传统的自动控制系统进行优化设计。阐述了SCR脱硝系统基本原理,简要分析了喷氨自动控制策略存在的问题,提出了采用智能软测量技术及智能自适应前馈技术的控制方式,成功应用于某660 MW机组SCR脱硝喷氨自动控制系统优化。High ammonia escape rate exists in SCR denitrification system of coal-fired power plants.In order to solve the problem of high ammonia escape rate,the traditional automatic control system must be optimized.This paper expounds the basic principle of SCR denitration system,and briefly analyzes the problems existing in the ammonia injection automatic con- trol strategy,puts forward the intelligent soft measurement technology and intelligent adaptive feedforward control method,ap- plied successfully in a 660 MW unit SCR denitration ammonia injection automatic control system optimization.
