Abstract: A method and a device for the hot-repairing of the heating flues of a coke-oven battery according to which the completed sections of a heating flue still under construction are heated by means of a heated gas. The heated gas comprises the air usually provided for combustion in the heating flues during coking operations. The air is guided through the flow paths provided for in the coke-oven battery for combustion air and waste gases as well as through the regenerator, heated as it passes through the flow paths and then guided through the heating flues to be repaired. The completed section of the heating flue is separated from the non-completed portion by an air-reversion device that also directs the heated air.

Abstract: The device relates to a device for leveling the coal filled in the retort of a coke oven, comprising a leveler bar (2) connected with a leveler bar drive (1) that can be moved into and out of the retort (4) through a leveling opening (3), and performs a leveling movement back and forth in the retort (4). According to the invention, the leveler bar (2) has a rake blade (5) on its front end with a width that can be adjusted by an operating device (6) arranged in the leveler bar (2).

Abstract: A coal charging car for a coke-oven battery has a screw-type feeder beneath the coal hopper shiftable on the chassis of the car to allow positioning of the outlet of that feeder over the hole communicating with the coking chamber without moving the car.
