Abstract
A method of producing glass using submerged combustion melting is disclosed. The method includes introducing a vitrifiable feed material into a glass melt contained within a submerged combustion melter. The glass melt contained in the melter has a redox ratio defined as a ratio of Feto total iron in the glass melt. The method further includes combusting a combustible gas mixture supplied to each of the submerged burners to produce combustion products, and discharging the combustion products directly into the glass melt. Still further, the method includes adjusting the redox ratio of the glass melt by controlling one or more operating conditions of the submerged combustion melter selected from (1) an oxygen-to-fuel ratio of the combustible gas mixture supplied to each of the submerged burners, (2) a residence time of the glass melt, and (3) a gas flux through the glass melt.
