Abstract
An oven wall three-dimensional profile data () representing concave and convex amounts on all over oven walls (R,L) at a right side and left side of a coking chamber () is generated by using image signals obtained by a wall surface observation apparatus (). A resistance index 'k' in which a resistance received by pushed coke () resulting from a rising gradient existing on the oven wall () is indexed is asked by using the oven wall three-dimensional profile data (). It can be verified that there is a correlation between this resistance index 'k' and a pushing load. Accordingly, it is possible to quantitatively evaluate a state of the oven wall () affecting on the pushing load.
