Abstract: The invention relates to an apparatus on a coal-charging larry cart for lifting lids out of charging holes in the roof of a coke oven and for cleaning the charging-hole jambs. The basic construction of this apparatus includes a lid lifter (3) having a support arm (4) carrying a lift magnet (5), a jamb cleaner (6) having a support arm (4?) carrying a cleaning head (7), drives (8, 8?) for vertically positioning the support arms (4, 4?). The lid lifter (3) and the jamb cleaner (6) are each mounted on a respective carriage (12, 12?) for horizontal movement between an operating position (A) in which the lift magnet (5) or the cleaning head (7) is aligned with a charging hole (13) in the roof of the coke oven, and a rest position (B) spaced from the charging hole.

Abstract: The present invention relates to a drive mechanism for vertical opening and closing of coke oven doors of horizontal coke oven chambers. The doors are lifted via a chain or a rope into the opened position. The rope or the chain is linked via deflector rollers to an actuating lever. The rope or chain can be pulled horizontally so that the doors are pulled-up vertically via the deflector rollers. The actuating lever is linked to a pull eye which upon actuation of the actuating lever can engage into the gripping cam of a gripping car. The gripping car is driven by a rope tackle and upon actuation of the actuating lever it pulls the door into the opened position. The door can be arrested via a suitable mechanism in its opened position.

Abstract: A device for latching of horizontal coke oven chambers which is triggered by an auxiliary frame located on the coke oven chamber door is provided. The auxiliary frame is restrictively movable in vertical direction on the coke oven chamber door. During the outward movement, the auxiliary frame hits upwardly against limit stop cams firmly mounted on the oven door and transmitting the vertical traction force onto the coke oven chamber door. During the upward movement, the auxiliary frame actuates levers which are rotationally movable to an axis arranged orthogonally to the coke oven chamber and which are connected to a translatorily freely movable latch. On actuation of this lever, it pulls the latch from the latch take-up bearings mounted on the coke oven chamber door so that the coke oven chamber door is unlatched and opened. In an embodiment of the present invention, the coke oven chamber door can be arrested in the open or closed position with a device suitable for this purpose.

Abstract: A device for pushing the contents of a coke oven chamber includes a pusher ram head with pusher rams mounted there behind, wherein guiding plates or aprons are mounted to a pusher ram head which avoid a simultaneous pressing-in of air into the coke oven chamber, thus preventing a non-desired cooling-off of the coke oven chamber during pushing. The aprons also prevent the pusher ram and the rearward side of the pusher ram head from excessive heat burdens. The aprons can also serve for protecting measuring devices mounted in the enclosure. The aprons can be fabricated from a heat-resistant metallic or ceramic material. The aprons or the pusher ram head can also be provided with a heat-resistant or heat-reflecting coating or with heat-resistant or heat-reflecting tiles. Also shown is a method for pushing of coke oven chambers by applying the inventive device.

Abstract: The invention relates to a method of positioning service equipment of a coal-charging larry cart at charging ports of a coke oven, wherein a rail-guided larry cart is moved on the roof of a coke oven and is positioned at locations known by a machine control system and corresponding to charging ports in the oven roof in order to charge the oven chambers, and wherein then at least one piece of service equipment of the coal-charging larry cart is guided to the charging ports by horizontal biaxial positioning movements. According to the invention, an optical measurement method is used after each positioning of the larry cart to detect the coordinates of at least one marking that is applied to the oven roof and that has a fixed relationship with the center axis of a charging port within a measurement field that is predefined by the measurement method and to compare them with reference values that are stored in the machine control system for the marking.

Abstract: The invention relates to a method of filling an oven chamber (1) of a coke-oven battery, wherein by means of at least one measuring unit (11) arranged on a leveling rod (9), and a processing device (5) connected to the measuring device (11), during the filling cycle within the oven chamber (1) the bulk material discharge process is determined in longitudinal direction, and wherein depending on the determined bulk material discharge progress, an additional loading of the oven chamber (1) takes place. According to the invention, by means of the measuring device (11), a three-dimensional filling level profile is contactless determined in longitudinal direction and transverse direction of the oven chamber (1). Subject matter of the invention is in addition a leveling apparatus for carrying out the method, comprising a measuring device (11) which operates contactless and which is arranged on a leveling rod (9).

Abstract: A process and device are disclosed for producing horizontally tamped coal cakes for coking in the oven chamber of a coking oven, the coal cakes being formed in a compression mold by stationary compression tools which work in the horizontal direction and with a stroke having a strictly limited length. The compression mold has a sliding stop wall which is moved away from the compression tools as the coal cake grows, under the effect of a suitable antagonistic braking force.

Abstract: This invention relates to a ventilation device for non-recovery coke ovens, said ventilation device consisting of at least one vent port extending through the wall or built-in internals, e.g. a coke oven door, and connecting the oven interior with the outer atmosphere surrounding said oven and wherein said vent port can be closed entirely or partly by means of a locking element. Two locking elements or more are coupled to each other by at least one mechanical coupling element by fastening said coupling element to said locking elements directly or via a lever, and wherein each coupling element is connected to at least one central adjusting element such that said locking elements can be moved, with it being possible for the relevant vent ports to be closed, completely opened or moved into any intermediate position. Ideally this coupling element should be a chain or a screw spindle.

Abstract: The invention relates to a method for the coking of coal, in particular coal with a high or alternating volatility, in coking plants comprising coking chambers, according to the non-recovery method or the heat-recovery method. The invention also relates to a device, which can be used to carry out said method simply, as the overheating of the coking furnace is prevented by the injection of water vapour. If a battery of coking furnaces is used, the disclosed method can be carried out irrespective of the number of said furnaces.

Abstract: Device for burning coking gas in a coking chamber of a coke oven of the “non-recovery type” or “heat-recovery type”, a multiplicity of inlet openings for primary air being arranged in the roof of each oven chamber in such a way that the coking gas produced during the coking is brought into uniform contact with the desired quantity of primary air for the partial combustion of the coking gas, these inlet openings for primary air being combined above the oven for each chamber separately by an air feed system, the air feed systems of the individual oven chambers being connected to an air feed system common to many oven chambers, and a respective control member for varying the primary air quantity over the carbonizing time being provided between the common air feed system and the air feeds of the individual oven chambers. A slight, constant positive pressure can be applied to the common air feed system.
