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.

Method and device for cleaning the door of a coke oven

A coke-oven door has an annular periphery normally juxtaposed with an annular door frame. A seal assembly for the door has at least two flexible, relatively displaceable, metallic, and annular membranes each having an annular inner periphery and an annular outer periphery and a U-section channel fixed to the outer periphery of only one of the membranes, open toward the door, and having annular inner and outer edges. The other membrane bears on the one membrane and therethrough on the channel. A mount secures the inner peripheries of the membranes to the periphery of the door. A spring urges the edges of the channel with a spring force against the door frame.

The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates (), which extend essentially over the entire length of the ranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers () which are arranged in the intermediate space delimited by the cheeks () at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between he cheeks (). The height () of the coal carriers (), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks () and the cheek form a gas channel () above the coal carriers () which is essentially free of built-in components.
