Abstract

See full text

Method of producing molten glass and system therefor, including providing a glass melting furnace configured to melt a glass sample, the glass sample including glass batch material including soda ash, or cullet or post-consumer cullet, or any combination of batch material, cullet and post-consumer cullet. The method includes introducing glass sample into a chamber of a rotary drum heat exchanger having at least one heat exchange tube; introducing the exhaust gas into the tube; causing a transfer of heat from the exhaust gas in the tube to the glass sample in the chamber to volatilize any organic impurities in the glass sample, heat the glass sample and evaporate water from the glass sample to dry it, the evaporated water forming water vapor in the chamber; contacting the dried sample with the water vapor; and discharging the dried sample from the rotary drum heat exchanger and introducing it into the furnace.
