Abstract
Abstract A method and apparatus for the evacuation of coke from a furnace chamber and for the wet quenching of the coke includes a coke box which is mounted for movement toward and away from the horizontal coking furnace. The coke box may be moved directly adjacent the furnace battery on a track which can place the box directly in front of the door frames of the furnace chambers. The coke box is made substantially to the dimensions of the coking mass to be received and it includes a bottom closure flap which may be opened after the coke box is moved away from the furnace and over a coke bin which also has a closable upper opening which is substantially of the plan dimensions of the coke box. The coke bin has a discharge arranged in a coke discharge flue at the bottom of the coke bin and means are provided to pass the coke into a quenching chamber which is provided with a chimney for advantageously includes spray means.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
53 words
A device, according to claim 1, wherein said coke box includes upright perforated plates defining a substantially vertically elongated coke receiving chamber with a gas exhaust chamber on the opposite side of said perforated plates, said gas exhaust chamber communicating with a vapor collecting chamber at the upper end of said coke box.
Claim 2
Dependent Claim
54 words
A device, according to claim 2, wherein said coke box includes a vertical elongated gas chamber on each side of said coke chamber which is connected at the upper end to said vapor collecting chamber, and separator means cOnnected to said vapor collecting chamber for removing the entrained dust from the vapors collected therein.
Claim 3
Dependent Claim
78 words
A device, according to claim 3, including slide plates on said coke box arranged adjacent the lower end of each side thereof and which are raisable and lowerable adjacent the lower end to provide a sealing of the lower end at the exterior of said coke box when said coke box is positioned in the top opening of said bin, said bin defining a sealing trough adjacent the opening for receiving the sliding plates of said coke box.
Claim 4
Dependent Claim
31 words
A device, according to claim 1, including means associated with said flue for removing and separating vapors and entrained dust, and quenching means in said chimney for purifying the exhaust gases.
Claim 5
Dependent Claim
43 words
A device, according to claim 1, including a plurality of coke boxes mounted for movement toward and away from the furnace chamber on said track means and a coke bin associated with each of said coke boxes each being connected to said chimney.
Claim 6
Dependent Claim
27 words
A device, according to claim 1, including an undercarriage movable in a direction transverse to said track means, said undercarriage including a beam defining said track means.
Claim 7
Dependent Claim
44 words
A device, according to claim 1, wherein said coke bin is positioned at a spaced location from said furnace chamber, said coke box being displaceable along said track means to orient the lower discharge opening thereof in the top opening of said coke bin.
Claim 8
Dependent Claim
66 words
A device, according to claim 1, including means defining an intermediate chamber at a level between said coke bin and said coke box, said intermediate chamber being connected to said coke bin and having a closing device associated therewith for isolating said intermediate chamber from said coke bin, said coke box being orientable to position its lowermost discharge opening to discharge first through said intermediate chamber.
Claim 9
Dependent Claim
136 words
A device, according to claim 1, wherein said bin comprises a fixed pocket having a top opening which is aligned with the bottom discharge opening of said coke box when said coke box is in position adjacent said furnace for receiving a massive coke therefrom, said intermediate pocket including a lower wall which is inclined downwardly to facilitate the discharge of the coke therefrom, said wall means defining the coke discharge chamber comprising a chimney having an opening through which the lower end of the pocket is adapted to extend, said pocket having a flap which may be opened to permit the sliding discharge of the coking mass into said chimney, said quenching means being located at the lower end of said chimney in a position to quench the coke which passes outwardly from said pocket.
Claim 10
Dependent Claim
21 words
A device, according to claim 9, wherein there is provided a sliding connection between said coke box and said receiving pocket.
Claim 11
Dependent Claim
29 words
A device, according to claim 9, including an undercarriage defining said track means and being movable transverse to said track means, said pocket member being carried on said undercarriage.
Claim 12
Dependent Claim
52 words
A device, according to claim 1, wherein said pocket member is connected to said coke box, and including an undercarriage supporting said track means and being movable transversely to said track means, said coke box with said pocket being shiftable away from said furnace to position said pocket within said discharge chamber.
Claim 13
Independent Claim
154 words
A method for effecting the discharge and quenching of glowing coke from a coking furnace using a coke box of a size to receive the mass of coke to be discharged and an intermediate bin or chamber, comprising pushing the coke into a coke box while quenching the coke at least along the top surface thereof as it arrives in the coke box and while removing the quenching vapor from the coke box, positioning the coke box in a position to align a bottom opening thereof over an opening of the bin, sealing the opening between the bin and the coke box during the discharge of the coke from the coke box, and permitting the coke to flow from the bin into a discharge chamber having a flue for the caRrying off of the gases while quenching the coke and while purifying the gases by a spray of quenching liquid and cleaning liquid respectively.
Claim 14
Dependent Claim
32 words
A method, according to claim 14, wherein said coke box is moved to said furnace to receive the coke and away from the furnace to position it in association with said bin.
Claim 15
Dependent Claim
21 words
A method, according to claim 15, wherein said bin is moved with said coke box toward and away from the furnace.
Claim 16
Dependent Claim
190 words
A coking furnace discharge apparatus for a horizontal coking furnace having a plurality of coking furnace chambers arranged in a horizontal row, comprising an undercarriage movable in a direction along the row of furnace chambers, a coke receiving box carried on said undercarriage and movable in directions substantially perpendicular to the direction of movement of the undercarriage in directions to approach and to move backwardly away from the individual furnace chambers, said coke receiving box being of a size to enclose the opening of each furnace chamber and being of a dimension substantially the same as that of the coking mass to be received from the furnace chamber, said coking box being movable after it receives a charge of coke from the coking chamber in a direction outwardly away from the coking chamber, at least one coke bin located along the path of movement of said undercarriage at a location below the path of movement of said coke box, said coke box and said coke bin having interengageable closure means which are openable to permit the discharge of the coke box into the coke bin without emission to the atmosphere.
Claim 17
Dependent Claim
83 words
A device according to claim 17, wherein said closure seal means comprises a closure flap associated with said coke box which is openable to drop all of the coke in said coke box into said coke bin while maintaining the seal therebetween, and wall means defining a coke discharge chamber below said coke bin with a quenching chamber portion and a chimney for the coking gases, and quenching means associated with said quenching chamber portion for providing a quenching action on the coke.
Claim 18
Dependent Claim
49 words
A device according to claim 18, wherein said coke discharge chamber comprises a chamber located directly below said coke bin and being sealed therewith and including a side chamber portion forming the quenching portion with conveyor means for transporting the coke discharged from said bin into said quenching portion.
