Intelligent Control of Coke Oven Production Process

Abstract

According to the characteristics and control demand of coke oven, research on intelligent control of coke oven production process was carried. Firstly intelligent control structure of coke oven production process was established. Then intelligent control of blending coal, collecting main pressure, combustion and heating intelligent control of coke oven were discussed simply, while production planning and scheduling was discussed in detail. The control principle of combining the intermittent heating control with the heating gas flow adjustment was adopted, and fuzzy compound control was proposed to establish heating intelligent control strategy and model of coke oven, which combined feedback control, feedforward control and fuzzy intelligent control. Production planning and scheduling of coke oven were optimized by using dynamic programming and genetic algorithm. The practical running indicates that the system can effectively improve quality of coke and decrease energy consumption, stabilize production of coke oven, and has great practical value.
