A coke oven hopper truck is movable along a coke oven cover which has therein filling holes closed by removable filling covers. The hopper truck has supported thereon a lifting device including an electromagnet which lifts and lowers the filling covers from and into the filling holes so that the filling covers may be removed from the filling holes, whereby coal may be charged through the filling holes into the coke oven chamber. The movable hopper truck has supported thereon repositories for supporting the filling covers after they have been removed from the filling holes by the lifting device. The repositories are movable with the hopper truck along the coke oven cover. The repositories have therein recesses dimensioned to receive therein the filling covers. Cleaning tools such as scrapers or brushes are provided along the edges of the recesses, and the lifting device rotates the filling covers against the cleaning tools to thereby clean the filling covers.

Coke oven hopper truck including support for removable filling cover

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. The poking bar is guided during the movement thereof to follow a predetermined displacement path such that the poking bar will avoid obstructions such as a quencher car located outside the coke oven chamber, such that the broaching head will be passed through the coke removal opening of the chamber even when the chamber door is only partially opened, and such that the broaching head will be positioned on the floor of the chamber. Movement of the poking bar thereafter will be guided by sliding contact of the broaching head on the floor, and possibly on the side walls, of the chamber.

Discharge apparatus for inclined coke ovens

An inclined chamber has vertical heating flues on each side thereof. The floors of the heating flues are vertically staggered in an inclined manner. Pairs of heating flues are joined at the tops thereof by guide openings which are vertically staggered in an inclined manner. Central and upper air inlet openings extend into the heating flues and are vertically staggered in an inclined manner.
