  • Patent number: 4029551
    Abstract: The coking installation has a row of coke discharge openings, a coke guide car mounted for travel along the row, a coke quenching car mounted for travel along the row and adapted to receive coke pushed out from the coke discharge openings through the coke guide car, and a suction arrangement for generating suction. A hood structure is mounted for travel along the row of coke discharge openings. The hood is connectable to the suction arrangement and movable into a position extending over the whole breadth but only a fraction of the length of the quenching car. Wind shields are provided on opposite ends of the hood in the region of the lower end of the hood. The wind shields extend horizontally in opposite respective travel directions of the hood and each has a breadth corresponding to the breadth of the hood.

  • Patent number: 3985245
    Abstract: Arrangement for charging the coal bins of hopper cars for coke oven batteries employing a telescoping sealing device with a lead aperture for the coal, for a dust-free connection between the charging hoppers in the filling position and the weighing bunkers, thus enabling the use of pre-heated or wet coal, maintaining short charging cycles, and permitting an exact determination of the charging volume needed, based on the weight of the coal.

  • Patent number: 3964977
    Abstract: An end wall of a horizontally extending coking chamber is provided with an opening through which a reciprocatable leveling rod projects with clearance into the chamber for leveling coal fed thereinto. Channel means communicating at one end with this opening surround with clearance the portion of the leveling rod outside the chamber. Air under pressure is fed into the region of the outer end of the channel means and sucked out from the latter from the region of the one end to thereby prevent gas to pass through the clearance between the rod, the opening in the wall and the channel means to the outside of the coking oven without feeding any of the air into the chamber.

  • Patent number: 3957591
    Abstract: A coking oven has an upright wall formed with an opening which is normally closed by a door past which noxious gases escape at least at times. Outwardly adjacent the opening and the wall are formed one or more upright channels having open ends located below and above the level of the opening, respectively, and being so positioned that escaping noxious gases can enter into this channel or these channels. Arranged adjacent the upper open end or ends is a suction conduit provided with apertures through which the gases can be drawn from the channel or channels to be conveyed in the conduit.
