ABSTRACT:
Apparatus and method for controlling emissions caused by pushing of coke from a coke oven. The apparatus includes an entrapment chamber extending alongside a plurality of ovens for containing the emission. Exhaust means for the entrapment chamber comprises a flow path restriction for accelerating gases leaving the entrapment chamber so that particulates are entrained in the gases and inhibited from settling in the entrapment chamber. Gas velocity is reduced in an expansion chamber downstream from and extending below the level of the flow restriction. The expansion chamber provides a settling region laterally offset from said flow restriction in which particulates fall out of the gases along a settling path whose gravity component is in a direction downstream from the entrapment chamber. The particulates which separate from the gases are collected in solids receiving means below the settling region and the gases leave the apparatus through exhaust means downstream from the expansion chamber and the solids receiving means. The flow restriction, settling region and apparatus exhaust means are in series relationship so that substantially the entire mass of the emission passes through the settling region.
