Abstract
The refractory lining of a high temperature chamber such as a coke oven chamber is inspected after a coke pushing operation and before coal is charged into the chamber by using a pusher ram to move a television camera located within an enclosure having water cooling pipes in the side walls thereof to provide a thermally-protective environment for the camera. The lens for the camera which projects from a side wall of the enclosure is air-cooled. The enclosure for the camera is rotatably positioned and vertically displaced relative to an L-shaped bracket used to support the enclsoure upon the coke engaging end of the pusher ram. In addition to displaying the video signal produced by the camera on a monitor, the video signal is also recorded to evaluate the surface condition of the refractory lining at a later period of time.
