Vertically Fired Furnaces

Instead of firing horizontally, these furnaces direct the flames almost vertically down onto the batch surface. This melting system can supply more energy per square foot of batch surface area without increasing refractory temperatures beyond normal operation limits. Hence, the furnace can melt more glass and/or a higher quality glass in a given size furnace (Worrell et al., 2008. p.62). Conversion to vertical fired furnaces, combined with oxygen boosting, have shown to provide a pure rate increase in excess of 50%, without affecting emissions or glass chemistry but reducing defects.
