  • Patent number: 9200225
    Abstract: Relatively high speed methods for increasing the bulk density of coal particles without impacting the coal particles and an apparatus for compacting coal for making metallurgical coke. The method includes depositing coal particles onto a charging plate external to a coking oven. The charging plate has side walls, and at least one movable end wall to provide an elongate bed of dry, uncompacted coal having an upper surface on the charging plate. The uncompacted coal is compacted by passing a vibratory cylindrical compactor along a length of the uncompacted coal for a number of passes sufficient to decrease a thickness of the bed of coal to less than about 80 percent of an original thickness of the uncompacted coal. The vibratory cylindrical compactor has a length to diameter ratio ranging from about 1.4:1 to about 2:1.

  • Patent number: 8152970
    Abstract: A method and apparatus for quenching metallurgical coke made in a coking oven. The method includes pushing a unitary slab of hot coke onto a substantially planar receiving surface of a hot car. The hot car containing the coke is then transported to a quench car station. The unitary slab of hot coke is pushed onto a substantially planar receiving surface of a quench car at the quench car station. Quenching of the slab of hot coke is conducted in the quench car with a predetermine amount of water. After quenching, the quenched coke is dumped onto a receiving pad for collection thereof.

  • Patent number: 7497930
    Abstract: Relatively high speed methods for increasing the bulk density of coal particles, apparatus for increasing the bulk density of coal particles and methods for making metallurgical coke. Once such method includes depositing coal particles onto a charging plate external to a coking oven to provide an elongate bed of dry, uncompacted coal having an upper surface of the charging plate. The charging plate has side walls, and at least one movable end wall An impact pressure is applied to the upper surface of the bed of dry, uncompacted coal while degassing the coal to provide a dry, compacted coal bed having a bulk density ranging from about 960 to about 1200 kilograms per cubic meter.
