Definitions

  • the present invention relates to horizontal coke ovens with a vertical discharge type of transverse regenerator having checkerwork consisting of checkerbricks placed one on top of the other.
  • Transverse regenerators extend parallel to the oven chambers and also parallel to the series of heating flues which extend across the width of the chambers forming the battery of coke ovens. These regenerators are connected to one or several adjacent heating flues.
  • the checkerbricks may include longitudinal ribs divided by crosswalls to form cross-sectional squares along the length of the checkerbricks.
  • the thickness of the ribs and crosswalls may be selected to correspond with the width of the flow spaces in the checkerbricks.
  • Such checkerbricks were placed one on top of the other with their longitudinal ribs extending parallel to the longitudinal walls of the regenerator.
  • the height of the longitudinal walls was selected so as to project beyond the crosswalls and thereby form a horizontal hollow channel which connects all of the continuous liow spaces in the checkerbricks between the overlying parts of the longitudinal walls. .
  • This .produces a concern that a blocking of the continuous flow spaces could occur at a location where a greater number of-bricks is provided as a result of falling mortar or brick fragments.
  • the eiciency of the regenerators could still be basically retained since a continuous liow of gases through adjacent spaces was made possible by the horizontallyarranged hollow channels. It has been discovered that the exposed upper edges of the crosswalls below the horizontal channels presented surfaces on which deposits of dust accumulate. Such dust deposits occur, foi example, due
  • the structure forming the vertical intermediate walls dividing the regenerator into cells must be independent of the longitudinal walls in the regenerator in view of the expansion phenomena of the oven masonry.
  • the bricks forming the intermediate walls are not connected with each other or with the bricks in the walls of the regenerator.
  • the regenerator walls are constructed, for example, from bricks which lit into each other.
  • Another aspect to be considered relates to the pressure equalization of gases passing through the regenerators at the intermediate Walls. It is desirable to dimension the regenerator bricks themselves in such a way as to prevent a horizontal flow of gases in a longitudinal direction of the regenerator, which is perpendicular to the intermediate walls.
  • a vertical disA charge regenerator formed by checkerbricks having in ⁇ ternal spaces divided into groups, one behind the other, and each group defining continuous flow spaces. These flow spaces are further characterized as vertically-extending passageways having a length and width defined by continuous crosswalls and longitudinal ribs, the latter being arranged parallel to the longitudinal walls of the bricks.
  • the invention further provides in such checkerbricks, that the relative height of the crosswalls and the longitudinal ribs in relation to the height of the outer longitudinal walls is such as to define depressions at the upper side of the bricks and projections at the underside of the bricks.
  • the bricks are arranged as courses of interfitting bricks, each course spanning the distance between the outer walls of the regenerator with courses arranged side-by-side along the width of the regenerator,
  • the depressions formed in the upper side of the bricks may be, according to an alternative arrangement, formed at the underside of the bricks.
  • the projections are then formed at the upper side of the checkerbricks.
  • the superimposed courses of checkerbricks are protected from mutual displacement in the transverse direction of the bricks since the outer longitudinal walls pass over the inner longitudinal ribs either above or below the latter where they are tightly placed on each other. This prevents escapement of gases in the longitudinal direction of the regenerator since the bricks occupy the entire width of the regenator.
  • the intermediate walls which divide the regenerator into cells are relieved of the usual tightitting requirements and may be arranged in an independent manner.
  • FIG. l is a fragmentary vertical transverse section through a row of coke ovens and regenerators
  • FIG. 2 is a fragmentary vertical section taken along line II-II of FIG. l;
  • FIG. 3 is a sectional view taken along line III-III of FIG. 2;
  • FIG. 4 is a sectional view taken along line IV-IV of FIG. 3;
  • FIG. 5 is a sectional view taken along line V-V of FIG. 4.
  • FIG. 6 is an enlarged plan view of a checkerbrick shown in FIG. 3.
  • each horizontal coke oven chamber 1 has side walls 2, a oor 3 and a roof 4.
  • the roof' is provided with vertical passages 5 for filling the ovens with coal that is to be coked, and with other passages 6 through which the gases formed during coking leave the ovens to enter small ducts 7 that are connected with large ducts 8 extending along the tops of the ovens. 'Ihe spaces between the ovens form heating flues 9.
  • each regenerator 11 which includes longitudinal walls 10A and 10B.
  • the space between these walls is divided by vertical crosswalls 12 into separate cells which is best shown in FIGS. 2 and 3.
  • the upper ends of the cells are connected by inclined passages 13 with the bottom of the flues.
  • a horizontal duct 14 admitting to the cells the air that is to be heated and to remove from the cells the combustion gases when the regenerators are reversed.
  • Each of the regenerator cells is filled with columns of superimposed checkerbricks 16 for alternately absorbing heat and imparting heat to incoming gases to preheat them.
  • the columns of bricks are supported side-by-side such that each checkerbrick extends longitudinally between the walls 10A and 10B where the bricks abut the vertical surfaces of these walls.
  • each checkerbrick has three groups of iow spaces 20, 21 and 22 arranged one behind the other longitudinally of the bricks.
  • the checkerbrick has longitudinal walls 17 and 18 and outer crosswalls 26 and 27. Within the outer walls there is provided three inner longitudinal walls 19 and inner crosswalls 23 and 24. Side projections 28 extend from the outer surface of the longitudinal walls 17 and 18. Other projecting surfaces 29 extend from the crosswalls 26 and 27 at the four corners of each brick.
  • the position of the bricks in the regenerator cell forms additional ow spaces 30 by 4 f the cooperation between the projections 28 on the bricks.
  • the design of the individual bricks attains the goal of assuring continuous ow spaces through the bricks and throughout the entire height of the regenerator cell and eliminating horizontal surfaces where dust deposits may be co1- lected.
  • the plates 34 and 35 are of different lengths such that the joint 37 is adjacent the wall 10B in the course of bricks shown in FIG. 3.
  • the joint 37 is staggered from course-to-course of bricks such that throughout the even-numbered brick courses, the joint is adjacent the wall 10B and throughout the odd-numbered brick courses, the joint is closely adjacent the wall 10A.
  • a vertical regenerator comprising:
  • regenerator walls extending along the. length of said coke oven chamber
  • each checkerbrick a recess formed in one horizontally-extending end of each checkerbrick and extending from one regenerator wall to the other regenerator wall along the entire longitudinal length of the checkerbrick, and
  • each checkerbrick a projection formed on the other horizontally-extending end of each checkerbrick and extending along the entire longitudinal length of the checkerbricks, the projection of one checkerbrick extending into the recess of a vertically adjacent checkerbrick, said checkerbricks defining outer longitudinal' walls that are independent of said recess and said projection.
  • regenerator walls have recesses for loosely receiving said crosswalls.
  • checkerbricks each comprise spaced-apart parallel arranged crosswalls, outer longitudinal walls and inner longitudinal walls defining groups of said plurality of continuous flow spaces, each of said groups being ar ranged one behind the other along the longitudinal length of the checkerbricks.
