  • Coke oven wall surface evaluation apparatus, coke oven wall surface repair supporting apparatus, coke oven wall surface evaluation method, coke oven wall surface repair supporting method and computer program
    Patent number: 8311777
    Abstract: An oven wall three-dimensional profile data (701) representing concave and convex amounts on all over oven walls (14R, 14L) at a right side and left side of a coking chamber (11) is generated by using image signals obtained by a wall surface observation apparatus (200). A resistance index “k” in which a resistance received by pushed coke (15) resulting from a rising gradient existing on the oven wall (14) is indexed is asked by using the oven wall three-dimensional profile data (701). 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 (14) affecting on the pushing load.
