Abstract

The amount of flexure of a heating wall of a coke oven is determined during operation of the coke oven by providing an observation hole through the oven roof into a heating flue, the observation hole having an axis. On at least one of the binder walls defining the heating flue is formed a vertical measuring strip extending throughout substantially the entire height of the binder wall at a position to be visible through the observation hole. The measuring strip defines, prior to heating during operation of the coke oven, a rectilinear reference line extending parallel to and spaced from the axis of the observation hole. Upon operation of the coke oven, during which time the heating wall is heated and flexes, the degree of such flexure is determined by measuring through the observation hole the extent of deviation of the measuring strip from the reference line.
