Definitions

  • the invention relates to a method for coking coal, in particular hard coal in horizontal chamber coking ovens by supplying heat and heating of the furnace fill filled from above over the longitudinal walls heated by gas burners, the released gas over the upper and the lateral gas collecting spaces running between the coke oven door and the curtained coking plate is dissipated.
  • the invention also relates to a coke oven with coke oven doors which close the top sides and which have a coking plate which is placed in the direction of the oven trimmings and is held at a distance from the door body by spacers.
  • a gas collecting space is created between the two flanges of the double-T support, separated by its web, which leads to advantageous pressure relief in this area and to a uniform removal of the released gas.
  • Even the gases released at the beginning of the coking process cannot escape into the atmosphere, which leads to a significant reduction in environmental pollution.
  • the coking plate in front leads to a kind of iron effect, i.e. for better cooking of the furnace heads directly in the area of the coking plate.
  • the layer of coking coal that can be influenced by the coking plate and thus the effect on the furnace heads is only slight and cannot be regulated or influenced.
  • Another disadvantage is that such a coking plate is difficult to handle, i.e. in particular, it can only be assembled and disassembled with great effort. Even with a subdivision of the coking plate, which is expedient anyway due to the expansion of the materials, there is still a great deal of effort for assembly and disassembly, in particular for coke ovens with 6 m and higher doors.
  • the invention has for its object to provide a coking process and a coke oven with coke oven doors, through which the top parts of the oven trimmings can be coked safely, selectively and evenly with the same or increased coke output, with an easily mountable and removable coking plate that is easily adaptable to the respective circumstances.
  • the object is achieved in that coking heat is supplied to the furnace stock from the long sides and at the same time from the two top sides.
  • the supply of coking heat to the furnace from both sides of the head is achieved by heating the coking plate.
  • the coking plate can be heated both by the discharged gases and by the radiant heat of the chamber wall and by the radiant heat from the furnace stock or the coke cake.
  • the gas flowing off to the side is first guided along the wall in the coke oven and reaches temperatures of 600 to 700 ° C. This hot gas then enters the vertical gas collecting space, flows upwards in the process and releases part of its heat to the coking plate. Calculations have shown that in a 7 m high furnace with a coking plate heated by the gas alone, an approximately 20 cm thick layer of coking coal can be coked on the coking plate.
  • the released gases are guided closely along the coking plate for a predetermined length.
  • This passage past the coking plate can be achieved by means of suitable intermediate installations, in particular by means of appropriately designed spacers, the gases being passed in sections directly to the coking plate and then being conducted away therefrom in the next section.
  • a coke oven with coke oven doors closing the top sides of the oven is used to carry out the method, which are equipped with a coking plate which, according to the invention, consists of individual overlapping shields, each consisting detachably with overlapping shields, each of which is detachably connected to the spacers.
  • Such a coking plate can be installed quickly and without too much effort and can also be dismantled if necessary, it being particularly advantageous that individual parts of the coking plate can be replaced or supplemented as required. If such a coke oven door is to be used, for example, after an overhaul in a coke oven which has a different mass, the individual shields need only be replaced by those with corresponding dimensions. Due to their overlap, there is a tight seal with respect to the furnace stock and at the same time a sufficient heat flow between the individual plates of the coking plate is guaranteed.
  • Reinforcing ribs are arranged on the inner wall to stabilize the individual shields. This makes it possible to connect the individual shields to the spacers only approximately in the middle.
  • the reinforcing ribs can be arranged as a double-T or parallel to the edges, depending on how the reinforcing ribs are used for connection to the spacers.
  • the shields which are rectangular in shape and protrude from the associated spacers in the longitudinal direction of the door body, are each connected to a spacer on one head side and are arranged with the other head side lying on the next shield in each case.
  • a type of scale armor is formed that can absorb expansion or shrinkage that occurs without special measures due to the temperature fluctuations.
  • the individual shield can thus also be firmly connected to the spacer, for example by screwing, which simplifies assembly and increases the stability of the construction. This is advantageous because knocks on the machine, on the coke oven or on the oven frame cannot be avoided when the coke oven door is removed and swung in.
  • Such shocks are harmless in such a construction because the individual shields are each provided with the spacers, i.e. are connected to their shield holders. On the other side of the shield, it always lies on the other shield connected to the spacer in this area.
  • the shields have two mutually merging bores on one head side and a longitudinal slot breaking through the edge on the other side of the head, the larger bore having the diameter of the collar of a Spacer attached pin and the smaller hole and the longitudinal slot in diameter are adapted to the neck of the pin.
  • the individual shields can thus simply be pushed over the pins attached to the spacers, and they also fix each other in the form of a shield armor. Even with large temperature fluctuations, the individual plates of the coking plate can “breathe” without changing their position on the spacers and thus on the coke oven door.
  • the spacers can advantageously be used at the same time to fix the insulating layer applied to the door body in that, according to the invention, the spacers consist of a U-shaped foot piece fixing the insulating layer and an upright U-shaped shield holder with the flanges pointing to the door foot.
  • the upright shield holders which influence or deflect the gas flow lead to the desired deflection of the gas flow or to its swirling and thus to better transfer of the gas heat to the coking plate. Since the shield holders are arranged in a U-shape and with the flanks pointing downwards, there is a targeted swirling effect or a jam of the gas.
  • Shield holders are also used for the formation of eddies and for better transmission of the gas heat to the coking plate, which are each formed as two angle irons arranged vertically on the foot pieces. Depending on the arrangement and design of these angle irons, the gas flow or gas vortex can be directed onto the coking plate and thus protrudes sufficient transfer of gas heat can be guaranteed.
  • sign holder or spacers can be seen in the invention in that the sign holder is designed as a parallel iron connected to the foot piece or the shields with flanks that are arranged offset and a plurality of spaced-apart holes or rows of holes exhibit.
  • sign holders or spacers are particularly suitable for applications in which the distance between the coking plate and the door body has to be changed from time to time.
  • only the screws or bolts in the corresponding holes need to be removed and, after a correspondingly different overlap of the iron or flanks, pushed back through the holes to achieve the desired distance.
  • a vertical displacement makes it possible in particular to adjust the distance between the lower trestle, i.e. of the last spacer to vary the bottom of the furnace in order to set the gap for the inflowing gas larger or smaller.
  • the spacers being formed from tube pieces which can be pushed into one another and have different diameters and which have corresponding bores for locking bolts at the free end.
  • the pipe sections with a smaller diameter are each connected, for example, to the coking plate and the pipe sections with a larger diameter are connected to the door body.
  • the individual pieces of pipe must then be pushed into each other, whereupon they each have a certain position, which then only has to be secured by inserting the bolts.
  • the reinforcing ribs are designed as upright flat irons and at least one side is in contact with the shield holders.
  • a particularly simple handling or inexpensive installation with correspondingly upright flat irons as reinforcing ribs can be achieved according to the invention in that the spacers or the shield brackets designed as angle irons have connecting bolts arranged at right angles and the associated reinforcing ribs have bores corresponding to the connecting bolts.
  • This limited flexibility leaves the individual shields the possibility to absorb thermal expansion and corresponding shrinkage.
  • the U-shaped spacers have a pin on the side facing the shields, the neck and collar of which correspond to the merging bores or the longitudinal slot.
  • the individual shields can be pushed onto or over the spigot and supported with the lower side on the spigot underneath or the spigot of the spacer underneath.
  • the pin By appropriately designing the pin, overstressing of this part protruding from the shields can be largely avoided.
  • the individual spacers also serve to fix the insulating layer on the inside of the door body. Contamination of this insulating layer and thus at the same time facilitating assembly and disassembly is achieved according to the invention in that the insulating layer on the side facing away from the door body is covered by a U-shaped plate which is held by the foot pieces of the spacers.
  • These sheets are expediently shorter than the shields and are arranged at a distance from one another in the area of the spacers and covered by the foot piece and held with play. The sheets are therefore not connected to the insulating layer, nor to the door body or the foot pieces. You can therefore easily perform length changes due to temperature fluctuations.
  • Moving the coke oven door into the coke oven is favored by the special shape of the lower end of the door body or the coking plate.
  • the sign holder or the spacer arranged at the lower end of the door body and U-shaped with its bottom is attached to the flanks pointing upwards or downwards, the upper flank serving as a sign holder and the lower flank at the end is bent obliquely upwards and both flanks are connected to one another via connecting webs.
  • the lower flank with the edged tip encourages entry, so that the door can be pushed into the coke oven practically resting on this foot.
  • coke or coking coal is penetrated into the free space of the U-shaped sign holder is prevented in that the lowermost sign corresponding to the U-shaped sign holder is designed to protrude beyond the folded flank.
  • a leveling rod opening is provided in the door body or in the coke oven door.
  • the leveling rod guide is designed such that when the leveling rod is moved back and forth, even coking coal cannot penetrate into the gas collection duct.
  • the gas collecting duct is covered by the bottom of the leveling rod guide.
  • the top plate of the machine-side door body and the leveling rod guide which consists of a holding frame detachably connected to the door body and a U-shaped guide plate attached to it, covering the gas collection duct, are designed as a structural unit are. Because of this design, the uppermost plate of the coking plate is mounted simultaneously with the screwing on of the holding frame and assumes the same position and stabilizes the guide plate or the coking plate composed of the individual plates.
  • the invention is characterized in particular by the fact that a method is created in which safe coking of the furnace heads is ensured, which at the same time improves the overall coking process and reduces emissions through the coke oven doors, in particular through the pressure relief in the area of the coke oven door as well as emissions from coke pressing.
  • the coking plate composed of the individual shields is given great mobility, which allows both thermal expansion and shrinkage to be absorbed.
  • the loads occurring when the coke oven door is moved in and out of the coke oven can be easily absorbed or compensated for.
  • the lower and the upper area of the coke oven door are particularly stable and easy to move.
  • the coke oven door 1 shows a coke oven with a coke oven door 1.
  • the coke oven door 1 is inserted with its door body 2 into the coke oven and seals the oven formed between the two coke oven walls 3 against the atmosphere.
  • the coking plate 6 held over spacers 4, 5 is arranged in front of the door body 2.
  • the coking plate 6 consists of several shields 7, 8, 68, which are each connected to one another and overlap each other. _ ____
  • the gas collection duct 9 is delimited on the one hand by the shields 7, 8, 68 and on the other hand by the door body 2 and by the coke oven walls 3.
  • the door body 2 is protected by the insulating layer 10, which is fixed to the inside of the door body 2 via foot pieces 11 of the spacers 4, 5.
  • the insulating layer 10 is additionally covered by the cover panel 49, 50 in order to protect the insulating layer 10 from contamination and to facilitate assembly and disassembly.
  • the furnace lining 12 is held at a predetermined distance from the door body 2 and behind it the gas collecting duct 9 is formed, which is divided into ducts 47, 48 in the area of the spacers 4, 5, where it is used for swirling or a targeted guidance of the gas flow comes towards coking plate 6.
  • the spacers 4, 5 connected to the foot pieces 11 are preferably screwed to the door body 2 via the foot pieces 11 and the retaining screws 51, 52.
  • connecting bolts 59, 60 are formed, over which the individual shields 7, 8 with the reinforcing ribs 14, 15 formed on the underside can be placed.
  • the Reinforcing ribs 14, 15 on appropriately designed and arranged bores.
  • the reinforcing ribs 14, 15, which are formed on the underside 16 of the shields 7, 8, can be arranged, for example, in the form of a double-T, wherein a central longitudinal web is connected to the reinforcing ribs 14, 15 designed as cross webs.
  • Fig. 2 shows a perspective view of the furnace lining 12 and serves to illustrate the coking process, namely the manner in which the furnace lining 12 is heated from the long sides 97, 98 and at the same time from the top sides 99, 100.
  • FIG. 3 and 4 show a spacer 4 in plan view and in side view with the upright angle iron 64, 65 and the connecting bolts 59, 60 striving at right angles therefrom.
  • These connecting bolts 59, 60 are arranged such that they point towards the furnace roof when installed. Then the individual shields 7, 8, 68 can be pushed onto these connecting bolts 59, 60 in order to form the connection between shields and spacers. Adequate lateral stability is achieved in that two connecting bolts 59, 60 are provided in each case.
  • the angle iron 64, 65 stand upright on the foot piece 11 in such a way that the retaining screws 51, 52 can be attached without further ado, which is also not hindered by the design of the flat iron 75 which connects the ends of the foot piece to one another.

  • the shields 7, 8 are attached, the shield 7 is first pushed over the pin 29, as can be seen from FIG. 9. This is possible due to the larger bore 34. Then the shield is pulled down so that the walls of the bore 35 now come to rest against the neck 31 of the pin 29.
  • the pin 29 can be extendable, for example in order to be able to use shields 7, 8 of different thicknesses or in order to press the shields tightly against the spacers. It has been found that the pin 29 with its collar 30 is not particularly well designed, since it projects into the glowing coke. A more favorable design of the pin 29 is therefore appropriate.
