Abstract
Sulfur oxides in the flue gases from a glass furnace are converted to sodium sulfate particles by introducing sodium oxide fume into the hot flue gases immediately downstream of the furnace. The fume is generated by forming a bed of carbonaceous material and sodium carbonate that is caused to react under hot reducing conditions. Sodium gas is thereby produced that burns above the bed to produce sodium oxide fume.
