Summary:To achieve stable operation of coke oven battery, numerical model for estimating clearance between coke cake and coke oven wall were developed. By developed model, influence of temperature distribution in combustion chamber on coke cake contraction was investigated. As a results, following findings were obtained.1) Drop of temperature in coke side (CS) gives higher drop of clearance at the end of coke chamber compared with machine side (MS).2) Drop of clearance at the end of CS causes higher pushing load of coke cake. Therefore, improvement of CS flue temperature is important for lowering pushing force of coke cake, particularly.
