Abstract
A method of producing flint glass using submerged combustion melting is disclosed. The method includes operating a submerged combustion melter such that combustion products are discharged from one or more submerged burners combusting a combustible gas mixture that comprises fuel and oxygen. An oxygen-to-fuel ratio of the combustible gas mixture ranges from stoichiometry to 30% excess oxygen relative to stoichiometry, a temperature of a glass melt in the submerged combustion melter is between 1200° C. and 1500° C., a residence time of the glass melt is maintained between 1 hour and 10 hours, and a specific throughput rate of molten glass discharged from the submerged combustion melter ranges from 2 tons per day per meter squared of cross-sectional area of the submerged combustion melter [tons/day/m] to 25 tons/day/m. A method of forming glass containers from the molten glass discharged from the melter is also disclosed.
