Definitions

  • the invention relates to a coke oven chamber with at least one oven door and at least one an outer and at least one inner door sealing strip, the oven door essentially completely surrounding gas channel.
  • the raw gas evolving in the coal filling is particularly important in a coke oven chamber at the beginning of the cooking under increased pressure, as it passes through the high coal bed it is difficult to climb into the gas collecting space above the bed can. This creates the risk that the parts of the door seal that this increased raw gas pressure in the coke oven chamber can not withstand the raw gas Penetrates the door seal and this leads to emissions.
  • the Raw gas development is lower and with it the emission behavior. Towards the end of the cooking arises as a result of the decreasing development of raw gas in the coke oven chamber a negative pressure in the lower coke oven area. This creates the risk of outside air is sucked into the coke oven chamber, which can lead to oven damage.
  • Coke oven doors are known in numerous embodiments that reliably one gastight closure of the coke oven chamber.
  • DE-OS 26 58 196 is a coke oven door with a gas channel completely surrounding the coke oven door is known, which is limited by elastic sealing strips.
  • This gas duct is with heating trains connected to the coke oven chamber in such a way that suction is caused. If so Raw gases flow into the gas duct through a sealing strip that is not completely sealed, the gases are sucked off into the respective heating draft. An exit from Raw gas from the furnace chamber into the atmosphere is thus reliably prevented.
  • DE-OS 26 11 414 discloses a door with a guide channel for deriving the from Coke oven exiting gases, the gases in the guide channel under a lower pressure than in the coke oven chamber in the coal bed area.
  • the inner bar is not gas-tight.
  • the side guide channels have in the lower area no connection with each other.
  • the inner door sealing strip of the guide channels should only Prevent coal from entering.
  • DE-OS 24 60 736 discloses a coke oven door with an annular cavity (Annular channel).
  • the ring channel is constantly under a slight vacuum compared to the Chamber interior as well as the outside air kept.
  • the invention has for its object to avoid emissions and Air intakes at coke oven chambers provide a sealing system that both the escape of raw gases from the coke oven chamber, as well as the air entry into the Reliably avoids the coke oven chamber.
  • the gas duct according to the invention which surrounds the coke oven door, has at least one connection to the gas collecting space.
  • the raw gas is in the coke oven chamber at the beginning of the cooking process Overpressure. Due to local pressure peaks, the raw gas can flow through the inner Get the door sealing strip into the gas duct. There it relaxes and is no longer in the Able to penetrate the outer sealing strip. Since the gas channel with the Coke oven chamber is connected, the raw gas that accumulates in the gas duct, into the coke oven without emissions. This also applies to Leaks, i.e. unwanted connections, on the inner door sealing strip.
  • a permanent connection of the gas duct to the gas collecting space is particularly effective unhindered formation of the gas plenum pressure in the gas channel.
  • the raw gas pressure in the coke oven chamber can reach a negative pressure sink (e.g. in the area of the furnace sole). Conversely, the raw gas can now flow out the gas channel through the inner sealing strip into the coke oven chamber. there is advantageous that no air can be sucked into the coke oven chamber, because the Gas channel is not filled with air, but with raw gas.
  • the gas channel is fluidly connected to the coke oven chamber. It turns out, as already shown in the gas channel in the sense of a gas pressure equalization the same pressure as in the coke oven chamber. This makes it possible to measure the gas pressure in the gas duct To influence or regulate chamber pressure control. This can advantageously be done with the chamber pressure control known from DE 43 21 676 C2 happen. According to this The regulation or control of the gas pressure of the coke oven chamber takes place via a patent Water level adjustment in the cup-shaped, arranged in the riser elbow throttle body that can be filled with water.
  • the gas channel is advantageously attached to the coke oven door. He can also be trained that it can be used as a retrofit kit for an existing coke oven door. This allows the emissions from existing coke oven chambers to be reduced with little effort to reduce.
  • Another possibility is to close the gas channel in the door frame of the coke oven chamber integrate.
  • the Gas channels basically have any cross-section. So he can z. B. in the form of a trapezoid be designed with unequal legs.
  • the door sealing strips of the gas duct can also have different door sealing cutting edge shapes exhibit.
  • the one-sided wedge-shaped design of the door sealing blade is preferred.
  • this wedge-shaped embodiment the sealing edge has shown the best sealing results.
  • the wedge side is critical.
  • the respective wedge side of the inner and outer door sealing strip in the direction of the upcoming higher gas pressure the relevant door sealing strip can be arranged. This will cause the tar condensate to form pressed into the wedge shape and thus improves the sealing of the door sealing strip.
  • the contact forces for the door sealing strips become decisive through the respective door locks affected.
  • one is Distribution of the contact pressure between the two door sealing strips required.
  • the contact forces are distributed in such a way that the inner door sealing strip has a higher one Contact pressure is experienced as the outer door sealing strip. This may be necessary because of the the inner door sealing strip pending higher pressure of the raw gas.
  • the distribution of forces must be determined on a case-by-case basis.
  • the different division of forces can e.g. B. by not simultaneously resting on the sealing surfaces of the door frame elastic Door sealing strips are made, i.e. the door sealing strips are with regard to the door frame executed different lengths.
  • the door sealing strips can also with different Bending behavior, e.g. B. executed by shape and by different wall thicknesses his.
  • the oven door according to the invention with a gas channel as a function of the cooking time to operate with a negative pressure close to 0 mbar in the gas duct at the beginning of the cooking and to remove the negative pressure in the gas duct towards the end of the cooking.
  • a low vacuum can e.g. B. with the Chamber pressure control mentioned above can be set. With the low vacuum it is almost impossible for ambient air to enter the gas duct. If there is air in would enter the gas channel, this could not lead to combustion in the gas channel, since the ignition limits for this gas mixture and the required gas mixture Ignition temperatures cannot be reached. So there is a risk of flame formation excluded in the gas channel. In any case, no air enters the coking coal filled oven area. There can therefore be no combustion processes on the furnace walls and their consequential damages come. The one with an unwanted, too strong vacuum operation Any air entering the gas duct would be discharged from the gas duct into the Gas collection room are removed.
  • the connections between the coke oven chamber and throttle the gas duct on the inner door sealing strip are carried out in such a way that it is from the outside and during furnace operation steplessly actuated across the range from fully opened to fully closed can be.
  • the adjustable throttles it is possible to control the gas pressure in the gas duct by opening or closing the throttle specifically and for each oven door.
  • This temperature range can be achieved by suitable measures, such as insulation or influencing the heat transfer of the sealing edges, removal of the excess Heat from cooling, such as B. cooling fins, and providing suitable heat transfers.
  • suitable measures such as insulation or influencing the heat transfer of the sealing edges, removal of the excess Heat from cooling, such as B. cooling fins, and providing suitable heat transfers.
  • With the right combination of insulation, heat and cooling it is possible to maintain the desired temperature range. It may be necessary be different combinations of cooling and the height of the coke oven door Provide insulation.
  • an oven door 5 is provided with one that surrounds the oven door 5 completely (all around) Gas channel 1 shown.
  • the oven door 5 closes a coke oven chamber 2 on the Coke side KS, which is filled up to a coal filling level 3 with coking coal.
  • Above the coal level 3 is the gas collecting space 4.
  • the gas duct 1 is through an inner door sealing strip 7 and an outer door sealing strip 8 limited. They form a door frame 14 of the coke oven chamber 2 open U, which is closed by the door frame 14 is by the door sealing strips rest on the door frame 14 (Fig. 2).
