Abstract
Furnace has a melting section into which batch is fed to a glass bath heated by electrodes, a homogenizing section, and a clarifying section therebetween in which fossil fuel burners heat the surface of the bath. The clarifying section is separated from the melting section by a first radiation shielding wall which extends to just above the bottom of the furnace and is interrupted by an opening above the glass for passage of combustion gases from the burners. A second shielding wall extends to above the surface of the bath and below the bottom margin of the opening in the first wall, so that combustion gases flow countercurrently through the incoming batch floating on the bath.
Claims10
Glass melting furnace with a melting section in which batch is added to a molten glass bath, a homogenizing section, and a clarifying section therebetween in which burners for the input of fossil energy are disposed, and between the clarifying section and the melting section a first radiation shielding wall extending to just above the furnace bottom to form an underpass for flow of molten glass between said melting section and said clarifying section, the first radiation shielding wall having an opening for the passage of the combustion gases, said furnace further comprising a second radiation shielding wall disposed in the melting section and having a bottom margin, the opening in said first shielding wall having a bottom margin which is above the bottom margin of said second shielding wall.
