Definitions
- the invention relates to a method for compensating radiation losses by thermal radiation during operation of coke oven chambers, wherein the radiation relates to a loss of heat through the coke oven chamber doors, usually through the coke oven chamber or end walls of coke oven chambers, and the compensation of the radiation losses is made by a special shaping of the coal cake, the in the door and end wall near furnace area a reduced loss of heat, which is required for the coking coal, and thus increases the coke quality in these areas and reduces the Ausgarungszeit the coal charge.
- the shaping of the coal cake is produced during the compaction of the coal cake, which is made by compressing the coal into a coal cake. Under shaping can be understood as a recess through which a portion of the coal cake is released, or an increase in which an increased amount of coal is poured up and pressed onto the coal cake.
- the loading of coke oven chambers is then carried out by methods of the prior art.
- a common embodiment for the loading of horizontal coke oven chambers is described in 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after which the compacted coal cake is pushed with the bottom plate in the oven chamber and the bottom plate is then withdrawn under frontal holding the coal cake from the oven chamber.
- horizontal coke oven chambers can be loaded, which are equipped with a floor heating.
- a compacted coal cake is loaded in the coke oven chamber, which has a regular shape.
- the shaping is intended to include an increase or decrease in the height of the coal cake, which increase or decrease in the height of the coal cake over the portions of the coal cake, which are located near the coke oven chamber doors.
- the invention achieves this object by a method which gives the coal cake a special shape during compaction which alters the height of the coal cake in loaded form in the vicinity of the coke oven chamber doors, this change being achieved by increasing or decreasing the height of the coke oven Coal cake done.
- the recess can be made by filling a reduced amount of coal in a Kompaktierform and pressing the same.
- the corresponding increase is made by adding a corresponding amount of coal, filling it with suitable laterally shaping elements and pressed.
- suitable laterally shaping elements are metal sheets.
- this Ausparung can be produced by the filled coal amount is not compacted at all at the lateral ends of the compacted cake and rests as a loose bed on the underlying Kohlekompaktat.
- Coal cake is compressed at a density of 700 to 1300 kg / m 3 .
- the compacted coal cake is filled through the loading port of the coke oven chamber into the coke oven chamber, and characterized in that
- an increase of the coal cake can be carried out, optionally also in combination with a recess.
- the height of the recess or the elevation may vary, but is preferably 20 to 700 mm in order to obtain the effect according to the invention. Typical heights of a compacted coal cake are 700 to 1300 mm.
- the depth of the increase or the recess of the coal cake can also be if varied, but is preferably 0.25 to 5 meters.
- the width of the increase or recess of the coal cake along the door can vary as desired.
- the density of the coal cake in the compressed form is usually 700 to 1300 kg / m 3 . If a recess is produced by a reduction in the density of the coal cake, then the density is expediently reduced by 20 to 300 kg / m 3 . This reduction in density can be achieved, for example, by leaving a recess free, filling the released recess with coal in bulk operation, so that the recess has a reduced coal cake density.
- the provision of a reduced density recess may also be combined with a normal increase or recess of the coal cake as described above.
- the cooking time in this cake area is reduced by about 4 of 60 hours per 100 mm height of the recess.
- the coking time per reduced in this cake area by about 5 60 hours 100 kg / m 3 reduced density per 100 mm height of the recess.
- any method can be used when it can be produced by an increase or recess.
- only the coal cake of the first and the last coke oven chamber of a coke oven bank or a coke oven battery are provided with an increase or a reduction of the coal cake. It is advantageous to provide the coal cake of the first coke oven chamber (first end furnace) of a coke oven battery or a Koksofenbank with an increase of the coal cake, and to provide the coal cake of the last Koksofenhunt (second end furnace) of a coke oven bank or a coke oven battery with a recess or increase , This recess or elevation is carried out not only on the door-facing side of the coal cake, but also on the side end walls of the coke oven chambers of a coke oven battery or coke oven bank. [0015] In a modification of the former method, a method for reducing the cooking time and for compensating radiation losses through coke oven chamber doors by adjusting the height or density of the coal cake, which is characterized in that:
- the coke oven chamber is part of a coke oven battery or a coke oven bank, and the first coke oven chamber of the coke oven battery or coke oven bank is provided with an increase or a clearance of the coal cake along the laterally terminating coke oven compartment end wall, and
- the last coke oven chamber of the coke oven battery or the coke oven bank is provided with a recess of the coal cake along the laterally terminating coke oven compartment end wall.
- the height of the recess or the increase of the coal cake of the first or last Koksofensch is, as in the case of a simple coal cake, preferably set up with 20 to 700 mm in height.
- the depth of the recess or elevation into the coke oven chamber typically corresponds to the entire length of the side coke oven chamber wall, but may be less.
- the width is preferably 25% by length of the door length.
- the number of coke oven chambers per coke oven battery or bank can be varied as desired.
- the recess or increase in the first and the last coke oven chamber can also be effected by omitting or adding a coal compact.
- the increase can be generated by dumping and shaking or placing one or more additional compactates.
- the dumping and shaking can be carried out by pressing and filling with lateral shaping elements.
- a recess is produced in the coal cake of the first and the last coke oven chamber, which is filled with a carbon compact or a carbon charge with a reduced coal cake density. If this procedure is used, the recess is typically filled with a coal cake whose density is reduced by 20 to 300 kg / m 3 .
- the reduced coal cake density can be produced by way of example by releasing, dumping and shaking.
- a coke cake which is produced by the process according to the invention and which is provided for loading in a coke oven chamber and for coking and for coking in a coke oven is used.
- Typical coke oven chambers in which coking is carried out with the coal cake produced according to the invention are coke oven chambers of the type "Non-Recov ⁇ ry” or heat recovery ". It is also possible. to use the coal cake produced according to the invention in conventional coke oven chambers.
- the described method by introducing a recess or an increase in a coal cake to be loaded into a coke oven chamber offers the advantage of improved coke quality in the door or endwandnahen areas due to reduced cooking time with reduced heat dissipation through the doors of coke oven chambers, which often reduced Have heat insulation.
- the method also offers the advantage of reducing the heat radiation through the lateral coke oven chamber walls of coke oven chambers by using coal cake produced according to the invention.
- FIG. 1 shows a coke oven chamber with recesses according to the invention in the coal cake in the vicinity of the coke chest doors.
- FIG. 2 shows a coke oven chamber with recesses according to the invention of reduced carbon density in the coal cake in the vicinity of the coke oven chamber doors.
