脱硝系统喷氨自动调节系统控制策略优化分析

Optimization Analysis of Control Strategy for Ammonia Injection Automatic Regulation System of Denitrification System

介绍了某电厂脱硝系统喷氨自动调节系统的控制策略,通过对喷氨自动调节系统控制逻辑的优化,使得脱硝系统出口NOx含量稳定在设计值,喷氨量也得到了合理的控制,避免了因控制策略不合理导致的喷氨量过大问题。

This paper introduces the control strategy of ammonia injection automatic regulation system of denitrification system in a power plant.By optimizing the control logic of ammonia injection automatic regulation system,the NOx content at the outlet of denitrification system is stabilized at the design value,and the ammonia injection amount is also reasonably controlled,avoiding the problem of excessive ammonia injection caused by unreasonable control strategy.
