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.

A method and apparatus are disclosed for recovering pure naphthalene from hot crude coke oven gas. The hot crude coke oven gas is directly cooled by means of sprinkling water directly thereon, and the naphthalene is recovered by subsequent filtering out of tar and other impurities, followed by cooling to obtain crystalline pure naphthalene. More specifically, after direct cooling of the hot crude coke oven gas, the gas is then guided through an electrofilter to be subsequently cooled in such a manner that the naphthalene contained in the crude coke oven gas is separated from the gaseous phase and is obtained in the form of pure naphthalene crystals without any required additional treatment.

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.

A coke oven has a coke-oven chamber adapted to hold a mass of coke, defining above the mass of coke a gas-collecting chamber, and having a door opening. A door closes the door opening. A peripheral gas channel extends around the opening between the door and coke-oven chamber and has at least one outer and at least one inner door seal defining an annular space. The inner door seal is formed in both the coke-oven chamber and the gas-collecting chamber with a plurality of throughgoing holes forming fluid-communicating connections between the coke-oven chamber, the gas-collecting chamber, and the annular space at different heights of the coke-oven chamber and of the gas-collecting chamber. Thus regions of the coke-oven chamber with different gas pressures communicate with each other and with the annular space via the connections on the inner door seal to equalize pressure between the regions and the gas-collecting chamber.

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.

The invention relates to a device for sealing a leveling door aperture of a coke oven chamber when loading bulk coking coal. The device includes a housing and a leveling door aperture, a leveling arm, composed of at least side panels and cross spacers connecting the side panels, is guided through the housing and the leveling door aperture. The leveling arm supports means for sealing a cross-sectional area of the leveling door aperture or upstream the leveling door aperture. A controllable or adjustable exhauster is joined to the housing and a measurement point is provided for flow rate measurement.

An arrangement for sealingly closing an opening of a reaction vessel includes a frame member which bounds the opening and a closing member which is movable between a closing position in juxtaposition with, and an opening position at a spacing from the frame member, as well as a sealing arrangement for sealing the gap between these members in the closing position of the closing member. The sealing arrangement includes an inner seal and an outer seal which define a sealing space filled with a preferably inert gaseous medium. The outer seal includes two sealing elements which extend across the gap in the closing position and define between themselves a confining space, and a liquid seal confined in this confining space. At the upper region, the liquid seal may be confined in an upwardly open horizontal channel and at the lower region it may be contained in a trough-shaped receptacle. The sealing liquid of the liquid seal is preferably circulated through the confining space to act as a cooling medium.

An infrared heat-image camera is aimed at a hot surface not perpendicular thereto but instead in a direction almost parallel to the surface, presenting to the camera a heat image of the surface not cartesian but instead highly distorted in accordance with the laws of optical perspective. The camera's output data is correspondingly non-cartesian and distorted with respect to organization and content, but the data is applied to a computer which transforms it to cartesian organization and corrects content, and then a corrected cartesian display is generated, simulating the heat image which would be presented to a perpendicularly aimed camera. Alternatively, the camera's scanning mechanisms are programmed to follow a non-cartesian scanning schedule, the geometry of which itself causes the camera output data to have the cartesian organization of a perpendicularly aimed camera. Preferably, the scanning schedule is modified to effect transformation to cartesian organization in only one direction, and transformation to cartesian organization in the other direction is computer-performed.
