燃煤电站SCR烟气脱硝喷氨自动控制方式优化

Ammonia Flow Automatic Control Mode Optimization of SCR Flue Gas DeNO_x for Coal-Fired Power Plant

介绍SCR脱硝的基本工艺,并对脱硝系统的喷氨流量的自动控制方法进行论述,提出以固定出口NOx控制方法代替固定摩尔比的优化控制方式。

SCR process is introduced and the ammonia flow automatic control methods of DeNOx system for power plant are presented.A constant outlet NOx concentration control method is proposed, which is a optimized control mode, to replace the constant mole ratio control method.
