Definitions

  • ABSTRACT Regenerative coke oven batteries have heating chambers on opposite sides of the coking chamber and the heating chambers have parallel spaced heating walls with a plurality of spaced flue walls extending transversely between and connected to the heating walls.
  • the flue walls form a series of vertical flues in the heating chambers. Combustion of the gaseous fuels takes place in alternate flues and the gaseous products of combustion are directed to flow downwardly in the adjacent flue for further transfer of heat from the gases to the heating walls.
  • the flue walls are formed of individual bricks in parallel courses with the bricks bonded to adjacent bricks.
  • Cylindrical passageways are formed in the bricks in spaced relation to the edges of the bricks, particularly the horizontal edges so that the bond between adjacent bricks is not interrupted by the horizontal passageways.
  • the flow of gases through the passageways is controlled by slablike dampener bricks.
  • the bricks are positioned in a generally vertical position parallel to the flue wall and are arranged to pivot in one direction into abutting relation with the flue wall and in overlying relation with the passageways to thereby control the flow of gas therethrough.
  • Regenerative coke oven batteries have a pair of heating chambers on opposite sides of the coke oven chamber.
  • the heating chambers have transverse flue walls that divide the heating chamber into a plurality of separate vertical flues.
  • the flues in the respective heat- .ing chambers on opposite sides of the coke oven chamber may be connected in a number of different fashions to circulate the products of combustion from the on flue or flues to the off flue or .flues.
  • the hairpin type oven for example, connects one flue with the adjacent flue in the same heating chamber so that the on flue is adjacent to the off flue and the products of combustion flow upwardly through the on flue, through a horizontal passageway I or passageways into the adjacent off flue and then downwardly through the off flue to the regenerator therebelow.
  • the hairpin type flues are illustrated and described in U. S. Pat. Nos. 2,845,385 and 3,431,177.
  • passageways are provided in the flue walls adjacent the base of the heating wall to permit recirculation of a portion of the products of combustion from the off flue to the on flue to thereby dilute the combustion gases in the on flue. It is desirable for optimum operation to control the flow of combustion gas through the respective passageways between adjacent flues.)
  • the flow ,of gas through the passageways was controlled by means of sliding bricks similar to the sliding bricks illustrated in U. S. Pat. No. 2,100,762. The bricks are moved horizontally by sliding on a support means into the desired position within the respective flues by means of a long rod that extends down the flue from the top of the oven.
  • the hereinafter described invention is directed to a damper for controlling the flow of gas through passageways in a coke oven flue walland includes a dampener brick with a generally rectangular configuration in section.
  • the dampener brick has a front wall, a rear wall, a top wall and a bottom wall.
  • the length between the top and bottom walls of the dampener brick is substantially greater than the thickness between the front and rear walls.
  • a support means is provided for the dampener brick adjacent to the vertical flue wall.
  • the dampener brick bottom wall is positioned on the support means in spaced relation to the flue wall and extends upwardly therefrom.
  • the dampener brick is arranged to pivot on the support means in a first direction to position a portion of the front wall in abutting relation with the flue wall and overlying at least one of the gas flow passageways to control the flow of gas therethrough.
  • The. dampener brick is pivotable in a second direction with the front wall in spaced relation to the flue wall to permit relatively unobstructed flow of the gas through the horizontal passageways.
  • the passageways in the flue wall extend through the bricks forming the flue wall and are spaced from the edge portions of the bricks so that the bond between adjacent bricks remains uninterrupted. It is preferred that the passageways have a generally cylindrical configuration and four passageways are provided in each of the bottom two courses of brick.
  • the dampener bricks are easily pivoted from an open to a closed position by the pivot arrangement and the cylindrical passageways eliminate the inherent weakness in the flue walls caused by the interruption in the brick bond between adjacent courses of brick.
  • the principal feature of this invention is to provide a damperbrick for controlling the flow of gas through passageways in the coke oven flue wall that is moved from an open to a closed position by a pivoting action.
  • Another feature of this invention is to provide a flue wall having passageways therethrough that do not interrupt the bond between adjacent brick courses.
  • FIG. 1 is a fragmentary sectional view in elevation of a pair of adjacent flues with a flue wall therebetween having cylindrical passageways therethrough and the improved dampener brick.
  • FIG. 2 is a view in vertical section taken along the line 11-11 of FIG. 1 illustrating in elevation the cylindrical passageways through the flue wall.
  • a heating chamber generally designated by the numeral 10 that has a pair of spaced heating walls 12 and 14.
  • a flue wall 16 extends transversely between and is connected to the heating walls 12 and 14.
  • the flue wall 16 forms a pair of vertical flues 18 and 20 in the heating chamber and other flue walls 22 and 24 extend between the heating walls 12 and 14 to form other flues within the heating chamber 10.
  • Vertical fuel supply passageways 26 and 28 are provided for the respective flues 18 and to supply the gaseous fuel for combustion within the respective flues.
  • Other vertical passageways. 30 and 32 are provided in the flues 18 and 20to supply air to the on flue and withdraw gaseous products of combustion from the off flue. For optimum combustion within the on flue, it is desirable at times to divert a portion of the gaseous products of combustion from the off to the on flue to dilute the gaseous mixture within the on flue.
  • the heating chamber has a base portion 34 on which the flue wall 16 is supported.
  • the flue wall 16 is formed from a plurality of separate bricks as, for example, bricks 38, and 42 in FIG. 2, .to form the bottom course of bricks in the flue'wall 16.
  • a second course of bricks 44, 46 and 48 is positioned on the first course comprising bricks 38, 40 and 42.
  • a plurality of other courses of bricks are positioned in overlying relation to each other 'to form the flue wall 16.
  • the individual bricks 38, 40 and 42 are bonded to each other as are the bricks 44, 46 and 48. Similarly the overlying courses of bricks are also bonded to each other.
  • the slab-like dampeners In order to control the flow of gas through the passageways there are provided a plurality of slab-like dampeners generally designated by the numeral 66.
  • the slab-like dampeners have a front wall 68, a rear wall 70, a bottom wall 72 and a top wall 74.
  • the bottom wall 72 has an arcuate configuration that is positioned in a mating arcuate recess 76 in the heating chamber base portion 34.
  • the arcuate recess 76 is spaced from the vertical flue wall 16 and is parallel thereto.
  • the slab-likedampener brick front wall 68 has an angularly diverging portion 78 that is arranged to abut the surface of the flue wall 16 when it is pivoted to a closed position as is illustrated in phantom lines in FIG. 1..
  • the dampener brick 66 may be easily pivoted in a first direction by a conventional rod member to a position where the diverging surface 78 of front wall 68 abuts the flue wall 16 and is in overlying relation with the passageways 62 and 54 to control the flow of gas therethrough. When it is desired to permit an un- 10 practice in the past.
  • the slab-like dampenerbrick 66 is pivoted in a second direction until therear wall 78 abuts a stop -member 80 formed in the conduit 32 as is illustrated in 5 FIG. 1.
