“In the past decades there have been numerous technological improvements made to the cupola including recuperative blast preheaters, oxygen enrichment, dust recycling, and emission controls. However, few theoretical studies have been conducted to predict the effects that design and operating changes will have on the cupola operation. The aim of this research was to study the effects of oxygen injection in cupola melting.
A study was conducted on the formation of sulfur oxides (SOx), nitrogen oxides (NOx), and their role in cupola melting. Theoretical calculations were performed to predict the effect oxygen enrichment would have on SOx and NOx emissions.
A thermodynamic model of the cupola was created using the PYROSIM software package. To represent the operation of the cupola, the model considered four zones, the melting, preheat, post combustion and quench zones. The model utilized Gibbs free energy minimization to predict the equilibrium composition in each zone. The effect of various levels of oxygen enrichment on the operating condition was studied.
Fluid flow modeling of the cupola was performed using the FLUENT software package. A three dimensional model was constructed in order to represent the location and number of tuyeres. The purpose of this modeling was to determine the effect of blast velocity and the number of tuyeres on cupola operation"--Abstract, page iii.
