Abstract: A device for automatically detaching and/or loosening coke within a coke oven chamber, particularly such a chamber of the type having an inclined or obliquely extending floor, includes a track support adapted to be mounted at a position confronting the coke removal opening of the coke oven chamber. An elongated poking bar is supported by the track support and has at a first end thereof a stoking or broaching head for abutting or scraping coke within the chamber. A trolley is mounted on the track support for movement therealong, and the poking bar is pivoted to the trolley. A reversibly operable cable drive moves the trolley and thus the poking bar along the track support from an initial position whereat the poking bar is positioned outside of the chamber to an operative position wherein the broaching head of the poking bar is inserted into the chamber to abut against coke therein.

Abstract: Separate temperature measuring elements are positioned on the outer wall surface of the riser of at least one oven chamber of a coke oven. During production of coke, the temperatures measured will be different. Upon completion of the coking process the difference between the measured temperatures will lessen to zero.
