ABSTRACT:
Method and apparatus for extruding incandescent coke from a coke oven and for quenching the coke prior to transport thereof from the point where extruded. The method and apparatus include enhanced air pollutant emission control characteristics. The apparatus includes an inverted, truncated-pyramid container cradled within the frame of a vehicle similar to that used to transport molten metal. Prior to coke extrusion the vehicle permits indexing of the container under the plane through which the extruded coke falls so as to receive all of such extruded coke. While indexed and immobile, the container is adapted to mate with a correspondingly indexed hood having emission control means adapted to be operable during both the extrusion and quenching of the coke at the indexed position of the container/hood. Use of the present invention, in comparison to the prior art, further minimizes the escape of uncleaned, air pollutant-emitting fume, both by virtue of combustion suppression and exhaust gas cleaning. The method and apparatus herein are subject to retrofit application on slot-type ovens converting coal to coke for metallurgical purposes wherein such ovens are subject to damage from misdirected water and steam.
