Definitions

• the invention relates to a process for compacting coal, wherein the obtained compactates constitute blocks or enlarged pieces of pressed or compacted coal which can be loaded into a coke oven without the loss of coal pieces.
• the invention also relates to the use of a method for producing Kohlekom paktaten which serve for loading of horizontal coke oven chambers.
• the loading of Kokshuntöfen can be done in many ways.
• Some types of coke oven chambers are loaded through the ceiling, which is advantageous for the design of the coke oven doors and the ejection machines. Loading takes place by means of special loading machines, which are mounted on the coke oven ceiling via loading openings in the coke oven ceiling. The cleaning of the coke oven ceiling is a difficult problem.
• Most types of coke-oven chambers are therefore loaded with front-opening coke oven chamber doors, which makes the loading process much faster and cleaner. For this purpose, doors are mounted on both front sides of the coke oven chamber, through which the coke oven chamber can be loaded and expressed.
• a common embodiment for loading horizontal coke oven chambers is DE 19545736 A1.
• the coal is poured out of the furnace at a uniform height on a flat bottom plate and then compressed, after which the compacted coal cake is pushed with the bottom plate in the oven chamber and the bottom plate is then withdrawn under frontal holding the coal cake from the oven chamber.
• This process can be used, in particular, to load horizontal coke oven chambers, which are equipped with underfloor heating. In this process, a portion of the coal is lost by the fact that coal pieces fall from the compressed coal when loading from the jig. Charcoal pieces may also fall in front of the coke oven chamber during loading.
• the metering of coal by this method is nau, because not necessarily exactly divided coal portions are given in the coke oven chamber.
• coal press cake with suitable devices describes the WO 2006/056286 A1.
• a coal cake is molded in a die by means of stationary dies which operate horizontally and with a limited stroke length.
• the mold has a sliding stop wall, which is moved away from the pressing tools with increasing coal cake under the action of an oppositely acting suitable braking force.
• the method compacts the coal cake prior to introduction into a coal transport car or coke oven chamber, but does not provide accurately measured portions of coal with which the coke oven chamber is then filled.
• the invention solves this problem by a pressing of coal, are made available by the compacted portions of coal, which are so dense that lost little or no coal pieces in the transport of coal portions.
• the coal compacts are produced by compression with a suitable pressing machine, which initially produces a large press cake, from which coal compacts of the desired size are made available with suitable cutting tools. These are stacked for coking and pushed with a jig or other suitable device in the coke oven chamber.
• the compacted coal compacts can be pressed with suitable shaped pieces during pressing, so that indentations, depressions or wave shapes are formed on the surface of the coal compactates, so that the coal cake has improved coking properties. This gives, for example, significantly shortened cooking times. Also, one can provide the Kompaktate with intermediate layers, by a back-pack of the compacts can be prevented. On the- For example, significantly improved storage properties of the compacts are obtained.
• a process is particularly claimed for coking oven-compatible compaction of coal by compressing and cutting coal, wherein
• the coal is pressed and compacted into one or more carbon blocks with a suitable pressing device, so as to obtain a dense and piece-free coal cake suitable for compacting coal,
• the coal cake obtained is divided into compacts by means of a shearing device, so that coal compactates are obtained which are lined up individually or horizontally or stacked on top of one another or horizontally strung together and stacked one above the other in a coke oven chamber to be loaded horizontally.
• the coal cake is first compacted according to prior art methods and then split into the desired portions with a suitable cutting tool.
• Suitable cutting tools are, for example, metal blades or saw blades. These can be arbitrarily shaped and have any number of sawtags.
• the cutting operation may also be carried out by a wire having sufficient thickness and thickness to cut the pressed coal cake.
• the wire can be made of any material.
• the metal blade, the saw blade or the wire can be moved horizontally and vertically with a hydraulic shearing device, thus dividing the pressed coal cake.
• the pressing process can be performed arbitrarily. This can be done for example with a hydraulic press. But this can also be done with a vibrating machine through which the coal pieces are compacted in a sufficiently compacted form. Finally, the pressing device can also be a hammering machine which hammers against pressure plates, so that the coal cake is brought into a compacted form.
• the coal cake can be placed on a stationary plate and pressed with suitable pressing devices laterally and from above.
• the coal cake can but with a Any device with a moving plate from one side, from several sides, or pressed from all sides.
• the pressure plates can be arbitrarily shaped. These can be smooth or equipped with appropriate shaping elements. Examples of shaping elements are wave forms, thick needles or indenting sting. These have a shaping effect and leave depressions, wave forms or depressions on the coal cake. This is for example for a shortening of the cooking time of significant advantage.
• the coal compacts produced in this way are introduced into horizontal coke oven chambers, which can be loaded frontally and which have a loading opening of sufficient size.
• the coke oven chambers to be loaded are preferably of the "non-recovery” or “heat-recovery” type, although conventional and horizontally loaded coke oven chambers can also be loaded therewith.
• the coal compactates obtained are stacked on top of one another for loading in the coke oven chamber. This can be done in any number and stacking way.
• Typical horizontal coke oven chambers are about 6 to 20 meters long, 6 to 10 meters high and 0.5 to 5 meters wide.
• the number of stacked compacts loaded into these furnaces is typically 5 to 30 in the longitudinal direction, 1 to 10 in the transverse direction and 2 to 8 in height.
• the number and size of the compacts can vary as desired. The same applies to the size of the coke oven chambers to be loaded. All that matters is that the compacts can be loaded into the coke oven chamber to be loaded.
• Suitable liners are, for example, ash or residue-free burning paper. In this way it is possible to prevent the compacted from baking back even during prolonged storage.
• the ash is removed after completion of storage or coking, for example, by blowing away. After coking, the usual coke cake is obtained, which can be further processed with the normal prior art processes.
• the coal compacts obtained are preferably loaded with a jig in horizontally loaded coke oven chambers.
• An example of a loading method with a setting machine is taught by DE 19545736 A1.
• any type of loading with which the coal compacts are transported into the coke oven chamber is suitable can be.
• This may also be a loading machine that has been modified as needed or, in a simple embodiment, a forklift.
• the process according to the invention has the advantage of providing coal compacts which permit coal-loss-free loading of coke oven chambers.
• the loading is done in portions and in an amount that can be calculated exactly and easily with a fixed portion size.
• the production of the compacts is easy.
• the compacts have excellent shelf life.
• the coal cake (1) Shown here is the coal cake (1), which was divided with a cutter into a number of compacts.
• the compacts (1a, 1b) can be seen here on the front (1a) and from the top (1b) of the coal cake (1), wherein the compacts are separated by a cut surface (1c).
• the actual coal cake (1) can be seen here on a mobile cart (2). This is pushed with a pressure device (3) in the coke oven chamber (4a). This can be seen here in the open state.
