Hybrid Intelligent Control of Coke oven

Aiming at the longitudinal temperature which was affected by many reasons, the control principle of combining the intermittent heating control with the heating gas flow adjustment was adopted. Control strategy and an integrated model of coke oven heating based on hybrid intelligent control methods were built. According to artificial operation and actual condition, fuzzy controller was designed. Intelligent control methods were used to compute the proper amount of stopping heating time and heating gas flow. The application of the system has resulted in energy saving by 2~4%, coke quality improvement by 3~5% and enhanced coke oven life. Obvious economic and social benefit is obtained.
