Definitions

  • An apparatus for ejecting coke from a coking furnace includes a coke box which is mounted on a car for transverse movement toward and away from the furnace doors and for longitudinal movement on a carriage along the length of the coking furnace battery.
  • the coke box is shorter than the coke cake to be received and it includes a movable coke cake guide arranged between the chamber door frame and a coke box.
  • the coke cake guide is movable along a platform alongside the furnace doors between the furnace doors and the coke box.
  • German Pat. application P I8 12 383.6 corresponding to U.S. Pat. application Ser. No. 880,976 concerns an arrangement for the emission-free ejection, receiption, evacuation and wet-quenching in a quenching tower of glowing coke which is ejected from horizontal coking furnaces.
  • the patent application discloses a coke box which moves on a track in front of the coking furnace chambers. This box has substantially the dimension of the coke cake to be received.
  • the box is provided with a bottom flap oriented to open into a coke bin arranged in the range of the track and which includes a closable upper opening.
  • the system includes a coke chimney flue arranged under the coke bin, and a coke quenching chamber with a chimney connected to the flue.
  • German Pat. application P I928 866.5 corresponding to U.S. Pat. application Ser. No. 880,976 concerns the arrangement of a coke receiving pocket underneath the cokebox, and the coke box is made shorter than the coke cake to be received.
  • the present invention relates to an improvement. of a construction in which the coke box is made shorter than the coke cake to be received.
  • This has the advantage that it can be subsequently installed in existing plants because of the small space required. It needs no separate coke feed but it also has the disadvantage that the door lifting, the door, and the door frame cleaning cart cannot pass by the coke box on the platform formed on the roof of the master gangway. This cart must always and constantly be on one side of the coke box on which it is arranged. A second such cart is therefore required for operating the furnace chamber arranged on the remote side at the end of the battery.
  • a door lifting device which can be moved completely independently of the coke box in front of the battery and with which the cleaning devices for the doors and the door frames can be combined, would therefore rep-' resent a technical progress.
  • the coke cake guide, the door lifting device and the door and door her of the furnace chamber ensures that there will be no gas-dust emissions when the coke is transferred from the furnace chamber into the coke receiving pocket. Care has been taken that no dust discharges into the atmosphere between the chamber door frame and the'coke guide applied thereto.
  • a suction pipe is arranged in the upper region of the coke box and it is connected to a duct in the upper region of the coke cake guide when the coke box is attached in front of the coke cake guide.
  • the pipe has, at its end, wide openings which permit the exhaust of dust from the chambers formed by door frames, tie rod stands, coke cake guide and packing plates arranged thereon.
  • the exhaust devices can be operated with fans or other exhausting means, for example, steam exhaust turbines which may also be equipped with wet separators or cyclone separators.
  • the coke box comprises a cast iron plate construction suspended loosely in a steel frame.
  • coke cake guide cars are arranged on a coking furnace battery which are alternately connected to the coke box and to the coke receiving pocket if desired.
  • a coking furnace construction which includes a coke box for receiving the glowing coke cake which is shorter than the coke cake to be received and which includes a movable coke cake guide arranged between the chamber door frame and the coke box which can pass freely along the coke furnace battery.
  • a further object of the invention is to provide a coking furnace apparatus which includes an undercarriage movable along the trackway in front of a coking furnace battery along the length thereof and a coke box carried on a car which is movable transversely on the carriage toward and away from the furnace doors and which also includes a coke cake guide which is movable on a ramp defined alongside the furnace doors at a location between the doors and the coke box.
  • a further object of the invention is to provide a coking furnace system which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is partial side elevational view of a coking furnace, battery having a coke discharge system constructed in accordance with the invention
  • FIG. 2 is a front elevational view of the discharging device shown in FIG. I; l
  • FIG. 3 is apartial top plan view of the furnace shown in FIG. 1 and FIG. 4 is an'enlarged partial plan of a portion of the apparatus adjacent the furnace shown in in FIG. 3.
  • the invention embodied therein comprises a coking furnace battery 1 which includes a plurality of horizontal coking furnaces arranged in a row.
  • the battery has a roof 2 and tie rod stands 3 at the furnace door end.
  • the front of the furnace is provided with a ramp 4 over which is movable a guide car 122 which contains a coke cake guide 99 which moves along the ramp 4 on the rails 123.
  • Tracks or rails 7 extend along the length of the furnace and an undercarriage or support structure moves along the tracks on wheels 10.
  • a coke box 11b is provided with a wheeled carriage 9 which backwardly and forwardly on a support beam 13 of the undercarriage 8 and in directions toward and away from the furnace doors at the location of the tie rod stands 3.
  • the glowing coke cake which is moved from each furnace chamber is pressed from the chamber through the cake coke guide 99 which is applied tightly to the furnace chamber to be emptied.
  • the coke cake is moved in the glowing condition through the guide and into the coke box 11b.
  • the coke box 11b is then moved backward a little and both the furnace chamber and the end face of the coke box 111) are closed with doors (not shown).
  • the dust vapors are withdrawn by steam exhauste rs 103 and 115 through lines 106 and 111 from the upper collecting chambers of the coke cake guide 99 and of the coke box 1112 as shown particularly in H0. 2.
  • the withdrawn vapors are delivered through lines 104 and 114 into cyclone separators 105 and 113.
  • This chamber is formed between the door frame 117, the walls of the coke cake guide 99 and the tie rod stands 3 together with the carriers 122 which are attached on the walls 118 and and the packing plates 119 which are secured on the carriers 122.
  • the withdrawn gasses are delivered through the slots 120 of the walls 118 into duct 98 which is arranged at the top of the coke cake guide 99 and into the line 100 which is arranged at the top of the coke cake box 1111.
  • This duct 100 is connected to the duct 98 when the coke box 11!; is attached in front of the coke cake guide 99.
  • the withdrawn gases are moved into a separator 109.
  • the vapors and the gases liberated of the dust are released into the atmosphere through the chimneys 105a, 108 and 112.
  • the separated dust is withdrawn from the lower part of the separators 105, 109, and 113.
  • the coke box 11b and the coke quenching cars are made of a steel frame construction with loosely suspended cast iron plates which can expand freely on heating and which are freely accessible as bin walls to the cooling outside air.
  • An apparatus for use in the discharge of glowing coke cake from a coke furnace having a plurality of furnace chambers arranged in a horizontal row comprising an enclosed coke box for receiving the coke cake, carriage means supporting said coke box for movement alongside as well as transversely towards and away from said furnace for presentation of said coke box in alignment with each furnace chamber in succession for receiving the coke therefrom, an enclosed coke cake guide movable between the furnace chambers and said coke box and defining a guide passage between said furnace chambers and said box for the passage of the glowing coke cake therethrough, gas exhauster means carried by said coke box adapted to extend into the upper part of each furnace chamber for removing the gases therefrom during the discharge of the coke, said gas exhauster means including an exhauster conduit carried by said coke box and extending outwardly therefrom for exhausting the furnace cases, a connect ing exhaust conduit carried by said coke cake guide and alignable with said exhauster conduit and having suction means engageable into the top of said furnace for removing the gases from the furnace through the conduit
