Abstract: Abstract:The principle and the technological process of selective catalytic reduction (SCR) method denitration were introduced. The processing principle of measured data of denitration system was expounded. Aiming at the shortcoming of original control logic, the control logic was optimized. The optimized control strategy can both control NOx removal and control the ammonia escape, and the control quality was improved obviously.

Key words: Keywords:flue gas denitration;ammonia injection control;feedforward control, ammonia escape rate, control quality
