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 closing the top sides, 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.
  • coke oven doors are already in use, in which a single plate is held at a certain distance in front of the door body by spacers.
  • the gas collecting space created in this way leads to advantageous pressure relief in this area and thus to a faster and more 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 placed in front leads to a kind of iron effect, ie to a better extension of the furnace heads directly in the area of the coking plate.
  • the layer of coking coal which can be influenced by the coking plate and thus the action on the furnace heads is only slight and cannot be regulated or influenced.
  • the invention is based on the task of creating a coking process and a coke oven with coke oven doors, by means of which the top parts of the oven trimmings are coked safely, selectively and uniformly with the same or increased coke output, with an easily mountable and removable coking plate which is easily adaptable to the respective circumstances.
  • the object is achieved according to the invention in that the furnace stock is fed from the long sides and at the same time from the two top sides of coking heat.
  • the supply of coking heat in the furnace stock from both sides of the head is advantageously made possible in that the coking plate is heated.
  • 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 out from the side is first guided along the wall in the coke oven and reaches temperatures of 6 00 to 7 00 ° C. Then this hot gas enters the vertical gas collecting space, flows upwards in the latter and gives some of its heat to the coking plate from. 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 in each case being brought directly to the coking plate in sections and then being conducted away therefrom in the next section.
  • a coke oven with coke oven doors closing the top sides of the oven which are equipped with a coking plate which according to the invention consists of individual overlapping shields, which are each detachably connected to the spacers, is used to carry out the method.
  • 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 other dimensions, the individual shields need only those with corresponding dimensions to be replaced. Because of 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. accomplishes.
  • 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, which can absorb expansion or shrinkage occurring due to the temperature fluctuations without special measures.
  • 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 connected to the spacers, ie to their shield holders. On the other side of the head Shield is always on top of 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 head side, the larger bore having the diameter of the collar of a Spacer attached pin and the smaller bore 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 shields of the coking plate can "breathe" without their seat on the spacers and thus on the coke oven door being changed.
  • 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 sign holders are arranged in a U-shape and with the flanks pointing downwards, there is a targeted swirl effect or Jam of the gas. This effect is further improved in that, according to the invention, the shield holders are attached to the center of the foot piece in the middle and with channels being left free. The gas is thus repeatedly directed against the coking plate, swirled and forced to pass or flow past the coking plate.
  • 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 an excellent transfer of the gas heat can thus be ensured.
  • the shield holder or spacers is to be seen in the invention in that the shield holder is designed as a parallel iron connected to the foot piece or shields with flanks which are arranged offset and a plurality of spaced-apart holes or rows of holes exhibit.
  • Such 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. With a change in the distance of the coking plate / door body, with such a design, only the screws or bolts attached to the corresponding holes need to be removed and, after a correspondingly different overlap of the iron or flanks, pushed back through the holes in order to to achieve the desired distance.
  • a vertical displaceability makes it possible in particular to vary the distance between the lower bracket, ie the last spacer, and the furnace floor 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. It is expedient to form the pipe sections as a square, so as to facilitate the drilling of holes and the handling during later assembly, if necessary.
  • a simple assembly in particular by a provisional resting of the shields on the spacers, can be achieved in that the reinforcing ribs are constructed as upright flat iron and at least with one side resting on the shield holders are.
  • a particularly simple handling or inexpensive assembly with correspondingly upright flat iron as reinforcing ribs can be achieved according to the invention in that the spacers or the shield brackets designed as angle irons have right-angled connecting bolts and the associated reinforcing ribs have holes 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 peg and are supported with the lower side on the peg below or the peg of the spacer underneath.
  • the individual spacers also serve to fix the insulating layer on the inside of the door body.
  • These sheets are expediently shorter than the shields and are arranged at a distance from one another in the region 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 plate holder or the spacer arranged at the lower end of the door body and U-shaped with its bottom on the door body up or. is fastened below, the upper flank serving as a sign holder and the lower flank being bent upwards at the ends and both flanks are connected to one another via connecting webs.
  • the lower flank with the upturned tip encourages entry, so that the door can be pushed into the coke oven practically resting on this foot.
  • coke or coking coal is prevented from penetrating into the free space of the U-shaped sign holder in that the lowermost sign corresponding to the U-shaped sign holder is placed over the edged one Flank protruding.
  • a leveling rod opening is provided in the door body or in the coke oven door.
  • the leveling rod guide is designed so that when the leveling rod is moved back and forth, even coking coal cannot penetrate the gas collection duct.
  • the gas collecting duct is covered by the bottom of the leveling rod guide.
  • the uppermost 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 simultaneously 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 both the opening expansion and shrinkage allowed.
  • the loads occurring when the coke oven door is retracted and extended from the coke oven can be well absorbed or compensated for.
