Definitions

  • An upright door for an end of the horizontal chamber of a coke oven is provided in its upper part with an opening for a bar by which coal in the oven is levelled.
  • a tubular casing is disposed in this opening and is adjustable vertically in it.
  • the casing has a substantially horizontal passage through it, and there are means at opposite sides of the casing for bolting it to the door at different levels.
  • the oven door is provided with substantially horizontal transverse walls extending outwardly above and below the casing ⁇ and spaced therefrom. At the outer side of the door there are means closing the outer ends of the spaces between the top and bottom of the casing and transverse Walls, and these spaces are filled with refractory material.
  • the outer end of the passage through the casing normally is closed by a door, and the oven door is lined with refractory below the tubular ca sing.
  • the charging level of the coal in the ovens is desirable to vary the charging level of the coal in the ovens; for example, to suit the different shrinkage capacities of the coal, or to control the gas conversion process taking place in the gas space of the oven by varying the height of this space, or to make allowance for the position of the upper gas reversal point in the neighboring heating flues.
  • the track of the leveller bar which is run in on the ram side of the oven battery through an opening in the oven door, must be adjustable vertically. This is also necessary when, at the end of part of the coking period, a layer of ne coal needs to be added and levelled by the levelling bar.
  • the leveller opening in the oven door must be suitably constructed.
  • the leveller opening has been made large and in front of it a sealing frame is arranged that is vertically adjustable or rotatable 180.
  • the opening in the leveller door can be made smaller or moved in height by means of wedge-shaped lining pieces inserted in the leveller door frame.
  • FIG. 1 is a fragmentary view of the outer lside of an oven chamber closure, with the leveller door removed;
  • FIG. 2 is a fragmentary vertical section through an oven and its closure taken on the line II--II of FIG. 1, showing the leveller door in place;
  • FIG. 3 is a horizontal section taken on the line III-III of FIG. 2;
  • FIG. 4 is a fragmentary view of the inner side of the oven closure.
  • FIGS. 5 and 6 are views corresponding, respectively, to FIGS. l and 2 but .showing a modification.
  • the opening at one end of the horizontal chamber 1 of a coke oven 2 is closed, during operation of the oven, by a closure that includes an upright oven door that is a vertical channel having a at web 3 and parallel vertical side flanges 4. Conventional means (not shown) hold the door in place.
  • the door is surrounded by a sealing strip 5 that engages the frame of the oven opening.
  • the upper part of the door is provided with a rectangular opening 6 for a leveller bar.
  • At the top and bottom of this opening there are horizontal, or nearly horizontal, walls 7 and 8 that extend outwardly between the ,side flanges, with which they are integral and form a frame around the opening.
  • a tubular casing 10 Disposed in the door opening 6 is a tubular casing 10, also rectangular, that is substantially as wide as the opening but has considerably less height so that it can be moved up and down in the door.
  • the casing has a subystantially horizontal passage through it for a leveller bar. It also has integral laterally projecting bolting anges 11 that overlap the bolting flanges 12 along the outer edges of side flanges 4 of the oven door.
  • integral with the top and bottom of the casing are vertical plates 13 and 14, stitfened by vertical ribs 15, that close the front ends of the spaces between the casing and the top and bottom of the frame around the door opening.
  • the casing is held in place by bolts 16 extending through the overlapping bolting flanges and through bars 17 engaging the outer surfaces of the casing flanges.
  • bolts 16 By forming the bolt holes in one pair of flanges, such as the casing flanges for example, as Vertical slots 18, it becomes possible to adjust the casing vertically Within limits without removing the bolts. For greater adjustment, the bolts are removed and the slots are positioned in front of different bolt holes in the door anges before the bolts are reinserted.
  • the casing extends forward from the oven door.
  • the outer end of the casing passage normally is closed by a cover 20 held in place in any suitable manner.
  • the casing also extends from the oven door inwardly into the oven chamber.
  • Slidably engaging the inner surface of the oven door above its opening 6 is a horizontal angle bar 21 that is secured to parallel end members 22 (FIG. 4) joined to the top of the inwardly extending portion of the casing.
  • the yspace between the casing and the angle bar and top of the door opening frame is iilled with heat insulating refractory material 23.
  • a transverse rib 24 on top of the inner edge of the casing helps to hold the refractory in place.
  • the space between the bottom of the casing and the underlying frame of the door opening is likewise filled with refractory material 25.
  • a transverse rib 26 beneath the inner edge of the casing bottom aids in holding the refractory in place.
  • the inner face of the oven door below the casing is lined and protected by refractory blocks 27.
  • the refractory material above and below the casing must first be removed. After the adjustment, the spaces above and below the casing are again tilled with insulating material.
  • the horizontal dot and dash lines 30, 31 and 32 in FIG. 2 indicate the normal charging level 30 of the oven, the lowest possible charging level 31, and the maximum charging level 32 when using a leveller bar.
  • the tubular casing which projects a Considerable distance into the oven chamber, protects to a great extent the lefveller door frame and the leveller cover from the intense heat.
  • the plates above and below the tubular casing 35 are not integral with it, but are separate at plates 36, 37 and 38, the ends of which overlap the bolting flanges 39 of the oven door 40 and are bolted to them. They close the front ends of the spaces above and below the casing and are filled with refractory material 41.
  • the casing does not extend into lthe oven chamber as it does in the first embodiment. Instead, a frame 42 is connected to the inner end of the casing and slidably engages the inner surface of the oven door above and below its leveller bar opening.
  • the lower transverse rib 43 on the bottom of the casing is at the outer end of this frame.
  • a closure for an end of the horizontal chamber of a coke oven comprising an upright oven door provided in its upper part with a leveller bar opening, a tubular casing of less height than said opening disposed in the opening and adjustable vertically therein, the casing having a substantially horizontal leveller bar passage therethrough, means at opposite sides of the casing for bolting it to the door at different levels, the door being provided with substantially horizontal transverse walls extending outwardly above and below the casing and spaced therefrom, means at the outer side of the door closing the outer ends of the spaces between the top and bottom of said casing and transverse Walls, and refractory material filling said spaces.
  • a coke oven closure according to claim 1 in which said door is provided at its opposite sides with parallel' vertical anges extending outwardly, said flanges and transverse walls forming a frame for said opening.
  • a coke oven closure according to claim 1 including a horizontal member slidably engaging the inner surface of the door above said opening, means connecting the ends of said member to the top of said casing, and refractory material llng the space between the casing and said member.
  • a coke oven closure according to claim 1 in which the tubular casing is rectangular with top and bottom walls, and the inner ends of said top and bottom walls are provided with transverse ribs partly overlapping said refractory material to help hold it in place.
  • a coke oven closure according to claim 1 in which said door is provided at its opposite sides with parallel Vertical flanges extending outwardly, said anges and transverse walls forming a rectangular frame for said opening, and said tubular casing is rectangular and extends away from the inner and outer ends of said frame.
