Summary

Forehearths used for borosilicate glasses typically suffer from problems related to their small size and the volatility of the glass constituents. Oxygen-gas firing can overcome some of these problems by reducing the volume flow of combustion gases and increasing the available heat from the fuel. This paper describes the installation and operation of oxygen firing on a forehearth conveying borosilicate glass for lighting components. We also present the resulting improvements in the control of the glass conditioning process.
