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.
Claims4
In an arrangement for removing gas emerging through the vertical and horizontal cracks bounding a closed coke oven door, in combination, a pair of vertical channels each extending along a respective one of the vertical cracks and each comprised of a first, a second and a third wall, the first wall being permanently secured to the door for movement with the door and being located to one side of the respective crack, the second wall being permanently secured to the front wall of the oven and located to the other side of the respective crack, whereby gas emerging from a vertical crack immediately finds itself intermediate the first and second walls of the associated channel, the third wall being pivotally connected to the first wall and swingable into a position in which the third wall presses against the second wall so as to complete the respective channel;
- means for holding each third wall in such position;
- a hood structure extending over the upper end of the coke oven door for capturing gas escaping from the upper horizontal crack;
- and means for sucking gas from the channels and from the hood.
