Abstract

The present invention provides a method and apparatus for accurately diagnosing a state of damage on a wall of a coking chamber of a coke battery. The method includes accurately diagnosing the damage state of the chamber wall by combination of three detection means. The three detection means include means for photographing the wall of the coking chamber of the coke battery, means for detecting the chamber width between chamber walls by laser range finders, and means for detecting the chamber temperature by radiation thermometers. The joints and the brick surfaces of the coke battery is photographed by a CCD camera. The image of the chamber wall is separated into images of the joints and the brick surfaces. The states of the joints and the brick surfaces are separately recognized to accurately detect damage of the joints and damage of the brick surfaces.
