Abstract

In order to solve the problems of SCR flow field and ammonia injection control

an optimization scheme of SCR flow field and ammonia injection control is proposed for a 660 MW unit. The application results show that the scheme can improve the uniformity of flue gas flow field

reduce the fluctuation of NO

concentration at the outlet of SCR

reduce the deviation of NO

concentration at the outlet of zone

and reduce the phenomenon of excessive ammonia injection.
