Heating Control of JN60' Coke Oven Based on Models

It is described in this paper for the heating control study on JN60' coke oven and application, the scheme of cascade control for flue temperature and feedforward control for draft used in the system, the strategy of fuzzy inference, establish of the mathematical model for heating control and technology, utilizes the coking index as the parameter on line to control coke quality. The results indicates that average energy conservation is about 3.5%, the temperature fluctuation is below 3℃,the steady coefficient of temperature is above 0.95.
