Abstract
In this study, we propose a new mathematical model of dissolved SO3 transport in a glass melting furnace, considering secondary decomposition of sulfate. The calculated concentration of SO3 agrees with measured data near the maximum temperature area, hot spot, in an actual glass tank furnace. The effect of onset temperature of secondary decomposition, the maximum solubility of SO3 and concentration of inlet SO3 on sulfate fining is quantified by simulation.
