Abstract: Enclosure and exhaust apparatus is provided to enhance control and removal of coke-side emissions during a push in the operation of a coke oven battery. The gaseous and entrained particulate emissions are initially confined to a first longitudinally extending containment zone where the emissions are directed, under the influence of its gaseous thermal drive, upwardly and laterally outwardly away from the coke-side face of the battery. The emissions are then transferred, at the peak of the first containment zone, laterally, through a gas expansion throat, into a second longitudinally extending containment zone that is adjacent and parallel to the first containment zone. Contemporaneously with entering the second containment zone, a portion of the emissions is removed therefrom through an exhaust conduit located at the upper reaches or peak portion of the second containment zone.
