OSTI ID:129101
A mathematical model was developed for estimating the clearance between the wall of the coke oven and the coke cake. The prediction model is based on the balance between the contractile force and the coking pressure. A clearance forms when the contractile force exceeds the coking pressure in this model. The contractile force is calculated in consideration of the visco-elastic behavior of the thermal shrinkage of the coke. The coking pressure is calculated considering the generation and dispersion of gas in the melting layer. The relaxation time off coke used in this model was obtained with a dilatometer under the load application. The clearance was measured by the laser sensor, and the internal gas pressure was measured in a test oven. The clearance calculated during the coking process were in good agreement with the experimental results, which supported the validity of the mathematical model.
