Establishment of Disturbance Model for Coke Oven Flue Gas Denitrification System

The modeling and control of coke oven flue gas denitrification system has always been acknowledged as a challenging problem due to the large delay and strong disturbance of the system. The disturbance model of the denitrification system is described using the CARMA model in this paper. The batch least squares identification method is used to obtain the model parameters after the disturbance model of the controlled object has been established based on the identification of data collected in the industrial field. According to the results, the disturbance model which was developed for flue gas denitrification system has a high degree of accuracy.
