Abstract: The invention relates to a method and a device for cleaning the door of a coke oven, said door comprising a sealing edge and a membrane that is attached to the door panel of the coke oven. According to said method, cleaning tools comprising jet nozzles, which are supplied with a flow medium at high pressure, are situated and displaced back and forth in the region between the sealing edge and the door panel of the coke oven, in such a way that the interior surface of the membrane and the sealing edge are cleaned. The coke oven door is cleaned directly after the coke oven chamber is opened, by at least one jet nozzle element, which is supplied with compressed air and is displaced along the sealing edges. The jet nozzles are oriented in such a way that the air hits the surface to be cleaned at an acute angle.

Abstract: Paneling of fireproof insulating elements for walls, floors and ceilings, comprises a plurality of metal-sheathed panels in edgewise abutting relationship. The panels are filled with endothermally variable insulating material that absorbs a great deal of heat during its phase change. To permit the panels to be welded together at their butt joints, the panels have double metal walls adjacent these joints, there being insulation within the double metal walls thereby to protect the endothermally variable insulating material from the heat of welding. A semi-solid, flexible insulating composition can be disposed in the butt joints. External insulating paneling, also arranged in edgewise abutting relationship, can be provided, the butt joints of the external paneling being offset from those of the internal paneling.
