Definitions
- the invention is directed to a method of making coke oven-compatible individual compacts from coke by non-mechanically dividing a carbon press cake, the carbon press cake being made by prior art pressing methods, and dividing the carbon press cake by non-mechanical energy-providing media.
- coal compacts are produced, which can be produced without further space-consuming shearing devices, so that a further transport of a pressed coal cake for the production of coal compacts is no longer required.
- 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 construction of the expressing machines. The loading of these furnace types takes place through special loading machines, which are mounted on the coke oven ceiling via loading openings in the coke oven ceiling. However, the weight of the loading machines on the furnace roof causes a disproportionate mechanical load on the furnace walls. This is associated with a reduction in the life of the furnaces. At the same time, the machines operating in regular sequences hinder the operations required for the furnace heating at the primary air metering openings on the furnace roof and can thus represent a considerable safety risk for the personnel working there. In addition, the cleaning of the furnace roof is a not negligible problem.
- loading machines and expressing machines are typically installed, which can be moved in front of the coke oven along the frontal walls and can be moved to the respective coke oven chamber for loading or unloading.
- a fire truck is arranged, which are also driven in front of the Kokshuntöfen along the frontal walls and that absorbs the hot coke after the coking process has been completed. In this fire truck, the coke is transported to the extinguishing tower for extinguishing.
- An example of the cutting of existing carbon press cake with mechanical tools is DE 102009011927.2.
- the compression of the coal portions into a compacted coal cake can take place in various ways, wherein the shaping is typically carried out by a pressing machine, which first forms a large press cake and from which coal compacts of the desired size are produced with suitable cutting tools. These are stacked for coking and pushed with a jig or with another device in the coke oven chamber.
- cutting tools are, for example, etalldegree or saw blades. Possible cutting tools are also wires or rods made of metal.
- spacers are introduced in one embodiment, which consist of a combustible material such as residue-free paper and ensure the separation of the individual compactates in the oven.
- These spacers prevent horizontal compression of the compacts produced due to the withdrawal of the setting plate during the setting process and burn shortly after the filling due to the high furnace chamber temperatures of greater than 1000 ° C. This produces the required gaps through which the raw gases can now rise and burn vertically into the combustion chamber above the coal cake. In this way, surface heating of the charge can be generated from above even with compacted feed coal, from which a high furnace output is derived.
- the coal is pressed and compacted into one or more portions of coal cake by means of a suitable pressing device so as to obtain at least one dense and piece-free coal cake suitable for compaction of
- Coal is suitable, which is characterized in that
- the coalcake obtained is divided into compacts with non-mechanical, shear-energy media, so as to obtain carbon compacts which are lined up individually or horizontally, stacked one on top of the other, or stacked horizontally and stacked one on top of the other or horizontal. nandergereiht stacked and stacked in a horizontally laden coke oven chamber to load.
- the non-mechanical, scherenergiearrinden media is in one embodiment of the invention is a laser beam.
- the non-mechanical, scherenergiearrinden media is in another embodiment, a high-pressure water jet.
- the non-mechanical, scherenergiearrinden media is in another embodiment, a high-pressure sand blast.
- laser cutting all laser beams can be used, which are suitable for cutting carbon press cake.
- An example of a laser beam suitable for carbon cutting is the C0 2 laser.
- An example of a suitable cutting method by means of laser beam is DE 19537467 C1.
- water jet cutting methods For cutting by water jets all water jet cutting methods can be used, which are suitable for cutting coal pressing blocks.
- suitable water jet cutting methods are abrasive water cutting or pure water cutting.
- An example of a suitable cutting method by means of water jet is the US 2008/0032610 A1.
- the method is suitable for cutting carbon press blocks and also allows the addition of abrasive materials into the water jet.
- For cutting the coal cake by means of Abrasivfest stressesen all methods can be used in principle, which are suitable for cutting coal cake.
- suitable abrasive solids jet processes are the dry process or the slurry process.
- An example of a sandblasting process for the removal of coal from rocky coal mines is GB 190408559.
- An example of an abrasive jet cutting process using a dry process is EP 2123402 A1.
- An example of an abrasive jet cutting process with slurry jets is DE 4430133 A1.
- the non-mechanical, scherenergiearrinden media may also be an air jet or a nitrogen gas jet.
- the air or gas jet can be heated.
- ultrasound or other media can also be used as a nonmechanical, shear energy dissolving medium. Ultrasound can be applied to the carbon using special tools that allow ultrasonic cutting. The said methods can be used individually, but they can also be used in combination.
- horizontal or vertical shape-stabilizing spacers made of a combustible material for producing a gap geometry by burning the spacers at high furnace temperatures are placed between the compactates produced in this way. These burn without residue during the coking process.
- the placement of the spacers following the division of the coal cake with a nonmechanical, shear energy delivering medium typically occurs before or during the loading process.
- the spacers have a thickness of up to 200 mm. These burn without residue during the coking process. These are made of paper, cardboard, wood or plastic, for example.
- the defined gaps thus produced have a width of at least 5 mm in the finished coke cake.
- the inventive method for producing kokshuntraten individual Kompaktaten is operated so that the resulting coal compacts are loaded in a horizontal coke oven chamber of the type "non-recovery" or "heat recovery". These use the coking gases produced during the coking to generate the coking heat.
- a horizontal coke oven chamber of the type "non-recovery” or "heat recovery”.
- the inventive method has the advantage that it can be made from a coal press cake coal compacts accurately, quickly and with great precision. By using a non-mechanical cutting tool, there is no abrasion. The development of coal dust is low by the use of the method according to the invention. The coal compacts produced are accurate in dimension and the cut channel depths are very well defined in their dimensions. As a result, an improved outgassing of the coking gases is possible.
