  • Publication number: 20120228115
    Abstract: A method and apparatus for transporting and quenching coke, useful in quenching a batch of coke produced in one of a plurality of coke ovens forming a coke oven battery, is disclosed. A hot car defining a substantially planar receiving surface is positioned adjacent a coke oven of the coke oven battery, and a unitary cake of unquenched coke is placed onto the hot car receiving surface. The hot car and unquenched coke are transported to a transfer station having a dust collection system. A quenching car is positioned at the transfer station adjacent the hot car, under the dust collection system. The unitary cake of unquenched coke is dumped into the quenching car receptacle, thereby separating the unitary cake. At least a portion of the dust generated by separation is collected. The quench car is then transported to a quenching station, where the separated coke is quenched.

  • Patent number: 6077399
    Abstract: The present invention deals with a method to produce uniform quality coke for a blast furnace by quenching coke at a pre-determined rate to produce coke with essentially uniform moisture; further, this invention possesses specific features to produce coke of uniform stability (strength) by equilibrating the temperature of the coke prior to its being quenched. Uniform moisture and uniform stability are very important factors that contribute to the efficient operation of the blast furnace to result in lowering the cost of making a ton of iron. This method is carried out under pressure, in a closed system, and in an environmentally acceptable manner with minimum formation of CO.sub.2. Further, the method possesses additional features which lead to the production of coke of higher stability than obtained conventionally.
