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. The remainder of the gaseous emissions, not immediately removed, are permitted to expand longitudinally and transversely within the second containment zone while carrying with it entrained particulates that also have not been removed through the exhaust system. Finally, the retained remainder of the gaseous emissions in the second containment zone are removed through the exhaust conduit while permitting those particulates that are heavy enough, to fall, by gravity, to a sloped bottom of the second containment zone and, then, to be discharged to ground at a convenient collection area.
