Abstract
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.
