Definitions

  • the invention relates to a method for improving the gas quality of the gas which is released or generated, in particular, when coking coal in horizontal chamber coking ovens, in which the gas is sucked off via the gas collection space which runs horizontally between the oven filling and the coke oven ceiling and is connected to the template 'of the coke oven battery.
  • the coking coal is filled from above into the approximately rectangular coke ovens and then heated and coked from the long sides.
  • the furnace filling is leveled mechanically in order to create a uniformly designed and sufficiently large-volume gas collecting space between the coke oven ceiling and the furnace filling, through which the gas is then sucked off over the entire length of the coke oven.
  • the coke ovens are opened on the sides through coke oven doors with door plugs made of refractory material limits, on the one hand protection for the coke oven doors themselves and on the other hand the most uniform coking of the furnace heads is achieved by pushing the furnace filling over the door plugs back into the area of the first heating flues
  • the heat from the first heating flue and the coke cake are largely removed, with a narrow channel remaining from top to bottom on both sides of the door plug between the door plug and the furnace wall.
  • a very small amount of gas can escape upwards along the door body through this narrow channel. Due to the formation of this narrow channel, high pressures occur in particular at the beginning of the coking process, so that the gas does not escape through the channels, but rather penetrates into the atmosphere through the sealing strip. This results in harmful emissions.
  • a disadvantage of the known coking process is that the resulting gases rise approximately 100 % through the furnace filling into the upper horizontal gas collecting space, in order to be sucked off into the receiver from here and used for further gas utilization. The gases are cracked, particularly as the coking process progresses, thereby reducing their liquid hydrocarbon content.
  • a further disadvantage is that the extracted gases have high temperatures in the area of the receiver and have to be cooled down for further gas processing.
  • the invention has for its object to improve the gas quality and at the same time to improve and even out the cooking of the top parts of the furnace filling.
  • the object is achieved according to the invention in that the gas is also sucked off selectively at the end faces of the coke oven.
  • the gas is sucked off and discharged at the end faces of the coke oven through a large-volume, vertical gas collection space corresponding in cross-section approximately to the gas discharge space formed above the furnace filling.
  • the gas is discharged through the large-volume vertical gas collection chamber at a temperature level that largely prevents condensation. This ensures that the door almost cleans itself, except for small residues in the horizontal area on the underside of the door. This significantly reduces the maintenance effort when operating coking ovens.
  • the gas quality can be decisively improved as mentioned, whereby tests have shown that the escaping gases in the region of approximately 45 ° below the upper edge of the furnace filling from the door to the interior of the furnace chamber no longer through the hot coke cake in the horizontal gas collecting space escape, but rather directly into the vertical, large volume gas collecting space with the correspondingly higher proportion of liquid hydrocarbons.
  • Gas collecting spaces is further improved according to the invention in that the heat carried by the gases and the heat of the first heating trains and the heat of reflection emanating from the coke is used to heat the coking plate.
  • the heat carried by the gases and the heat of the first heating trains and the heat of reflection emanating from the coke is used to heat the coking plate.
  • a uniform degassing of the furnace filling in the area of the coke oven door is ensured, which both facilitates gas removal in this area and also increases the amount of gas with a higher proportion of liquid hydrocarbons.
  • the gas supplied to the receiver is at a temperature which is about 50 ° lower points than when only the horizontal gas collecting space is present.
  • the invention is characterized in particular by the fact that an increase in the liquid hydrocarbons in the gas increases the value of the gas obtained, and at the same time an improvement and homogenization of the gas quality is ensured by the uniform cooking of the head parts.
  • FIG. 1 is a partial perspective view of a coke oven door with a large-volume gas collecting space formed on the inside.
  • the figure shows the essential parts of a coke oven door with the side facing the coke oven facing upwards.
  • the door body carrying the fittings is designated by 1.
  • Sealing strips are arranged on the side, which rest against the door frame when the coke oven door is swiveled in, thereby leading to the desired sealing of the coke oven from the atmosphere.
  • the specially designed and designated 4 door plug is arranged, which protrudes correspondingly far into the furnace chamber and leaves lateral, narrow passages for the gas between the door panel and the door body 1, the large-volume gas collecting space 7.
  • the gas can rise from the bottom of the furnace chamber to the riser pipe arranged in the area of the ceiling and into the receiver.
  • thermal insulation which protects the door body and a cooling of the by Prevents gas collecting space 7 streaking gas.
  • the labeled door plug 4 is here formed by the T-shaped spacers 18, 19 and the lying thereon sections 29, 3 0, 31 of the plate sixteenth
  • the individual sections 29, 31, 31 are arranged at a certain distance from one another and lie on the larger flange of the spacers 18, 19.
  • Reinforcing irons 25, 26 are placed on the individual sections 29, 30 , 31 so that the plate 16 itself can be made from thin sheet metal.
  • the illustration shows that the gases in a vertical gas collecting space designed in this way penetrate very well past the plate 16 and can then be sucked off through it.
  • the individual spacers 18, 19 do not constitute a hindrance to the extracted or discharged gas, especially since they are arranged at a distance from one another.
  • the leveling box is designed such that the gas can be guided past it laterally.
  • the * heat-resistant plate 16 is preferably made of a metal or steel with a high thermal conductivity, heat is supplied from the gas to the furnace filling, so that these parts are not only heated laterally from the heating walls, but also via this plate 16 and be heated.
  • the resultant flawless removal of the head parts leads to an improvement in the gas discharge in this area into the gas collection space and, at the same time, produces significantly lower emissions when coke is pressed, since full coke is present here.
