This article discusses the five key factors that need be considered in the selection of a batch glass melt furnace.
Corrosion Resistance
The lining used in batch glass melt furnaces (Figure 1) must be able to tolerate the highly corrosive fumes that are often produced by glass chemistry at elevated temperatures.
Corrosion resistant materials such as cast zirconia for a temperature range of 1800 to 1200 °C and high alumina ceramic for temperatures up to 1700 °C are used for the required corrosion resistance.
Furthermore, it is recommended to deploy a 'spill trap' instead of a flat hearth plate in order to collect spills from “boil-overs” or broken crucibles.
