智能脱硝控制系统的应用研究

Application Research of Intelligent Denitration Control System

针对目前选择性还原脱硝控制系统延迟大、惯性大,调控精确性差的不足,提出了一种新的智能脱硝控制系统,利用自适应前馈控制的理论实现了对喷氨量的精确调整,根据仿真分析表明,该控制系统能够将控制反应时间提高了66.7%,显著提升了脱硝的控制精确性和经济性。

Aiming at the shortcomings of large delay,large inertia and poor regulation accuracy of the current selective reduction denitration control system,a new intelligent denitration control system is proposed,which realizes the accurate adjustment of ammonia injection by using the theory of adaptive feedforward control.According to the simulation analysis,the control system can increase the control reaction time by 66.7%,and significantly improve the control accuracy and economy of denitration.
