Abstract

We have developed a measurement method to measure both heat radiation and shapes of the whole surface of refractory blocks in a carbonization chamber of a coke oven under high-temperature conditions. An apparatus of our method consists of an area camera, two line lasers and a specially designed optical filter that divide field of view of the camera into two regions: one for imaging radiation and the other for catching only laser lights for shape measurement. The apparatus moves in the chamber of a coke oven to scan refractory blocks. One conventional problem is that the measured shape data contains a distance from meandering during moving through the 16m-length of the chamber. We have developed a signal processing to remove the disturbance using this feature
