Abstract: A heat-resistant door device for closing a horizontal coke oven chamber is made of a refractory material, using a material containing silica or a material containing silica and aluminum oxides, in particular. The material has a low temperature expansion coefficient and it is thermally well insulating so that the door is not deformed and/or distorted during the coal carbonization process. The door device is built of a coke oven wall mainly located above the door and embracing the door as well as of a mobile door located underneath. Thereby less cold ambient air enters into the coke oven chamber and radiation losses are minimized. The door may be comprised of an ellipsoidal bulge by, which the coke can be better pushed into the coking chamber. The oven wall embracing the oven door can also be made of a refractory material containing silica or of a material containing silica and aluminum oxides.

Abstract: A method for compacting coal in a manner suitable for coke oven chambers is disclosed. The coal is initially compressed by means of a suitable compressing device into one or more coal cakes, and the obtained coal cakes are divided into compacted products by a cutting device. The compacted products are stacked on top of the each other such that they can be loaded into a coke oven chamber for coking. The compacted products enable the coke oven chambers to be loaded in a precise and a coal loss-free manner. The coal compacted products are easy to store.

Abstract: A method for reducing the coking time in the oven area near the door or end wall and for improving coke quality and situation of emissions by compensating for radiation losses through coke oven chamber doors and end walls is disclosed. This compensation is accomplished by varying the height of the coal cake in the environment of the frontal coke oven chamber doors. The variation is achieved both by increasing or decreasing the coal cake over part of the length or over the entire length of the coke oven chamber door. The reduction in the height of the coal cake can be generated by omission of coal or coal compacts, the increase in height can be accomplished by stacking of coal and pressing or adding of coal compacts, with it also being envisaged to omit the pressing cycle so as to obtain a recess with a lower coal cake density which also has less heat radiation.

Abstract: Improvement in carbonization in a carbonization furnace and simultaneous reduction in NOx emissions is achieved by recirculation of waste gas from a coking oven back to the oven chamber, the downcomers, or the sole channel system.

Abstract: Dosed proportioning and cutoff of combustion air into the primary heating space of a horizontal coke oven is provided by apertures in the ceiling of the coke oven chamber, the apertures covered with a withdrawable cover device which controls the amount of air admitted, manually or in an automatic mode. By way of this device, ventilation of a coke oven chamber with primary air can be so controlled that primary air is introduced in an exactly dosed manner and, depending on its place of installation, exactly distributed into the primary heating space of a coke oven chamber.

Abstract: Coal compacts which are suitable for coking in coke oven chambers are prepared by pressing and compacting coal in a pressing device having a design which shapes the surface of the coal compacts to provide higher surface area. Already compacted coal blocks can be pressed to generate the surface shape. The resulting coal compacts exhibit significantly improved properties during the coking process, resulting in improved gas and heat exchange. A device for compacting coal preferably contains a plate provided with shaping elements on the pressing surface.

Abstract: A method for cyclical operation of a coke oven facility which includes an even number of coke oven banks which in turn include an even number of coke oven chambers is shown. Located downstream of the coke oven banks are boiler facilities which drive turbines with the hot waste gases from the coke oven banks. Energy is recovered in this manner. The coke oven chambers are pushed and charged in an exactly determined cycle so that the production of hot waste gas over the temporal mean can be homogenized.

Abstract: A device for proportioning of secondary combustion air into the secondary air soles of coke oven chamber ovens is shown. The device is formed by a slide gate or a parallelepiped device or by plates moved by means of a thrust bar, the thrust bar being moved longitudinally in parallel to the coke oven chamber wall so that the plates move away from the secondary air apertures and open or close these. The thrust bar is moved by means of a positioning motor, with the power transmission being effected hydraulically or pneumatically. Via suitable measuring parameters, it is thus possible to optimize secondary heating so that heating is provided evenly from all sides, thus achieving an improvement in coke quality.

Abstract: A device for directed introduction of primary combustion air into the primary heating space of a coke oven chamber is shown. Primary air is admitted through entry ports in the top of a coke oven chamber or in the frontal coke oven chamber walls above the coke oven chamber door or in the coke oven chamber door or in several or all of the mentioned positions These entry ports have inserts that are equipped with oven-inwardly directed spouts, with the spouts having an opening-outwardly directed angle through which primary air is conducted at a chamfered angle onto the coke cake so that the primary air from the opening ports in the coke oven chamber top streams to the coke oven at an angle of less than 90° and primary air from the opening ports in the coke oven chamber wall above the coke oven chamber door or in the coke oven chamber door streams to the coke oven at an angle of greater than 0°. Also shown is a method for a directed introduction of primary air with the described device.

Abstract: A device for a directed gas routing of primary air into a coke chamber oven is disclosed. The primary air is conducted through the coke chamber top into the gas space of a coke oven battery and is laterally deflected as it enters into the gas space of the coke chamber. Also disclosed is a method for lateral deflection of primary air after its entry into the coke oven chamber, thus improving the distribution of the primary air in the coke oven chamber.

Abstract: A device for feeding and controlling secondary air from secondary air ducts into flue gas channels of horizontal coke oven chambers is shown. The flue gas channels are located underneath the coke oven chamber floor on which coal carbonization is realized. The flue gas channels serve for combustion of partly burnt coking gases from the coke oven chamber. The partly burnt gases are burnt with secondary air, thus heating the coke cake also from below to ensure even coal carbonization. Secondary air comes from the secondary air ducts connected to atmospheric air and to the flue gas channels. Controlling elements are mounted in the connecting channels between the flue gas channels and secondary air ducts which can precisely control the air flow into the flue gas channels. Thereby, it is possible to achieve a much more regular heating and heat distribution in coke oven chambers. The actual controlling devices in the connecting channels can be formed by turnable pipe sections, wall bricks, or metal flaps.

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.
