Abstract

This presentation will show the influences of the lateral shrinkage of coke and the compressibility of coke cake on the pushing force of coke cake from the oven chamber which has irregularity on the wall surface. The pushing force of coke cake can be determined by the clearance between the coke cake and the wall surface, which is controlled by the lateral shrinkage of coke, and the irregularity of the wall surface (concavity and convexity), which are commonly observed in coke oven chambers which operate for a long period. If the achieving temperature at center of coke cake is not enough comparing to the one in the normal operation, the pushing force is affected by the compressibility of the coke cake.
