3. Electrically heated melting furnaces
3.1 General design
The heating principle of these furnaces is very different from that of flame furnaces 2 , as the thermal energy is transferred into the molten glass, rather than to the surface of the glass bath in flame furnaces.
The electrical fusion of glass is based on its ability to conduct electricity from 800-900°C, with conductivity increasing with...
