ABSTRACT:
A method and apparatus for treating cullet before use as a raw material in a glass manufacturing process is disclosed. The method includes providing a bed of cullet; passing hot gases through the bed, the quantity and temperature of gases being sufficient to pyrolyze odor creating impurities within the bed of cullet; entraining volatile products of pyrolysis into gases leaving the moving bed; heating the gases leaving the bed to oxidize odor creating impurities; and discharging the gases to the atmosphere. The apparatus includes a housing containing a moving bed of cullet; a source of hot gases which permits the gases to pass through the moving bed of cullet to pyrolyze odor creating impurities within the cullet and entrain volatile products of pyrolysis into gases leaving the moving bed; and an incinerator to remove odor creating impurities from gases leaving the moving bed.
