Influence Of Glass Furnace Operational Conditions On The Evaporation From Soda-Lime-Silica And Borosilicate Glass Melts

The evaporation of sodium and boron species from the melts in industrial glass furnaces leads to emissions of particulate material (dust) and to furnace atmospheres containing reactive evaporation products. These reactive species, especially alkali vapors, can react with the superstructure refractories causing chemical attack on the materials. The vapors form condensation products during the cooling process in the flue gas channels, recuperators or in regenerators, causing deposition of salt. In some cases, this deposition leads to reduced heat transfer in heat exchangers or blockage of the flue gas channels.
