Definitions

  • the invention relates to a coke oven battery consisting of several coke ovens, in which each coke oven has an oven chamber, the oven chamber delimiting heating walls on both sides, and a heat recovery part and an oven ceiling, with a transverse anchoring of the heating walls, which has vertical anchor rods extending over the height of the coke oven battery and Upper cross anchor in the level of the furnace ceiling and lower cross anchor in the level of the furnace substructure for the anchor stands as main support elements as well as door frames and wall protection plate constructions, which the horizontal loads from the anchor stands, which act on them via pressure elements on the heating walls, especially the end faces the runners, transferred.
  • the object of the present invention is to design a coke oven battery of the type mentioned at the outset in such a way that an improved load distribution of the transverse anchoring for the heating walls can be achieved with little technical means. It is also important that weight savings are achieved for door frames and wall protection panels.
  • the wall protection plate construction is divided over the chamber height into several articulated wall protection plates or plate sections and the pressure elements are arranged both in the area of the subdivision points and at the upper and lower ends of the wall protection plates. This construction makes it possible to bring the temperature deformation back to a level that tends towards zero.
  • the subdivision points of the wall protection plate construction should form essentially horizontal hinge axes.
  • Such a construction which has a plurality of articulated connection points and correspondingly arranged pressure elements over the chamber height, permits load centering in the longitudinal axis of the rotor stones and therefore enables the appropriate adjustment of a load distribution desired over the chamber height.
  • the possibility of load centering and the flexibility of the design over the entire chamber height, with which an ideal load distribution is achieved while simultaneously acting on temperature differences, leads to a lighter design with significant material savings and thus to weight and price savings in production. It can also achieve a better seal of the oven door area with the proposed construction, because the usual maintenance costs due to the intensive maintenance work between the door frame and the wall protection plate are eliminated.
  • the service life of the refractory masonry and thus the coke oven battery is significantly increased in that the desired load distribution over the chamber height can be adjusted by means of an appropriate number of wall protection plates or plate sections and an adapted force and number of pressure elements.
  • the new construction not only makes the wall protection panels considerably lighter, it may also be possible to dispense with a door frame. This also leads to considerable cost savings.
  • the susceptibility to repairs of the wall protection plates is also considerably reduced due to the lower static stress due to the design according to the invention.
  • the wall protection plate construction is in the area of the furnace ceiling, e.g. formed on a bracket-suspended panel link apron from a plurality of stacked wall protection plates, the, preferably substantially horizontal, butt joints of which are covered by a relatively thin cover plate.
  • This cover plate is made of a suitable material, e.g. Steel with which the desired flexibility of the construction is achieved while achieving a seal.
  • the cover plate can extend over the entire height of all wall protection plates of a panel link apron.
  • Sealants are preferably provided in the butt joints of the wall protection plates and / or between the wall protection plates and the cover plate, in order both to achieve a tightness to the outside and to avoid raw gas spills.
  • the pressure elements can have horizontally adjustable pressure bolts which are supported on the anchor stands by pressure springs. This ensures a certain degree of flexibility, which is necessary for operational reasons.
  • compression springs are expediently accommodated in a protected manner in spring housings which are fastened to the anchor stands.
  • the pressure bolts can act on pressure clips, which in turn are the Transfer pressure forces to the butt joint ends or simultaneously to the upper and lower ends of the wall protection plates. In this way, the necessary pressure forces can be applied in a simple manner.
  • an externally machined metal lamella for the sealing contact of the sealing edge of the furnace door is exchangeably fastened to the cover plate.
  • this metal lamella can be easily replaced, so that the tightness of the furnace door can be restored and guaranteed without great effort.
  • a special door frame is not necessary.
  • the anchor stands, preferably directly above the walkway, have a releasable, rigid joint connection.
  • FIG. 1 shows a furnace head of a coke oven battery with the anchoring consisting of anchor stands 1, upper and lower transverse anchors 2 and 3 and pressure elements 4.
  • the coke oven battery shown in detail has several coke ovens standing vertically next to one another, each with an oven chamber 21, which is delimited on both sides by heating walls 6 and together with them forms a removable unit between two rigid concrete heads 26 (FIG. 2).
  • Such a coke oven battery also has a heat recovery part 22, which in the case shown is designed as a regenerator and is arranged below the oven chambers 21.
  • the coke oven battery also has an oven ceiling 23 running above the oven chambers 21 of the coke oven battery.
  • the transverse anchoring of the heating walls 6 is formed by the vertical anchor stands 1, which extend over the height of the coke oven battery, as well as upper transverse anchors 2, which act in the plane of the furnace ceiling 23, and lower transverse anchors 3, which act in the plane of the furnace substructure 25, for the anchor stands 1 as main support elements .
  • the cross anchor construction also has wall protection plate constructions designed as plate link aprons, which are suspended from brackets 31 in the upper region of the anchor stands 1 and which transmit horizontal loads starting from the anchor stands 1 and acting on them via the pressure elements 4 to the heating walls 6, in particular the end faces 5 of their rotor stones .
  • each wall protection plate construction is divided over the chamber height into a plurality of wall protection plates or plate sections which are connected to one another in an articulated manner, the dividing points between the wall protection plate sections forming horizontal articulated axes 8 and the pressing elements being arranged both in the region of the dividing points and at the upper and lower ends of the wall protection plates. It is thus achieved that the wall protection plate construction is divided into a plurality of wall protection plates 9 arranged one above the other and combined to form an apron, which extends flexibly over the entire chamber height and whose plate members can be load-centered on the rotor stones as required.
  • the substantially horizontal butt joints 10 between the wall protection plates 9 are covered by a relatively thin and thus light cover plate 11 made of steel and connected to it.
  • This steel plate 11 extends in the case shown over the entire height of all wall protection plates 9 of an apron. Due to the ideal introduction of the horizontal loads according to the invention as a result of the load-distributing design in the abutment and end region of the wall protection plates in the transverse direction, the edge fiber 7 of the rotor stones is not subjected to tension in order to avoid cracks. Rather, the load is applied centrally. Sealants 12 are provided in the butt joints 10 of the wall protection plates 9 and between the wall protection plates 9 and the cover plate 11.
  • the pressure elements 4 ensure good load-centerability and thus uniform load introduction regardless of the prevailing temperature conditions, both in the area of the joint axes and at the upper and lower ends of the wall protection plates 9.
  • the pressure elements 4 have horizontally adjustable, e.g. designed as threaded bolts with actuating head pressure bolts 15, which are resiliently supported by pressure springs 13 on the armature stands 1.
  • the compression springs 13 are protected in the spring housing 14, which are attached to the armature stands 1.
  • the pressure bolts 13 act on pressure brackets 16, which preferably bridge the butt joints 10 and which in turn transmit pressure forces to the butt joint ends 17 or the upper and lower ends of the wall protection plates 9.
  • cover plate 11 On the cover plate 11 is also an externally machined metal lamella 20 for the sealing contact of the sealing edge of the (not shown) furnace door replaceable.
  • the sealing cutting edge could also cooperate in a sealing manner with the cover plate 11.
  • the anchor stands 1 have a detachable, rigid butt joint immediately above the walkway 19 in order to make repairs in the refractory area even easier.
  • each furnace chamber 21 with its two heating walls 6 is accommodated between concrete heads 26.
  • the concrete heads 26 are clamped at the top by means of pins 28 arranged on the longitudinal beams 27.
  • the furnace ceiling 23 is bounded at the bottom and the heat recovery part 22 at the top by a slip joint 24.
  • the interior of the profiled wall protection plates 9 can be filled with insulation 29 and refractory granules 30.
  • the furnace ceiling 23 consists essentially of chamotte, as does the heat recovery part 22.
  • the heating walls 6 and the furnace sole consist, for example, of silica and the furnace substructure 25 is made of concrete.
