<p>A apparatus for simultaneously preheating cullet and removing pollutants from glass furnace gases is disclosed. Raw moist cullet having fine glass dust material and other impurities adhered to its surface is heated by furnace gases which remove the moisture and the impurities by entrainment. The dry, clean cullet is then electrically charged and used to filter the exhaust gases which have been electrostatically charged.</p> |
