Submerged combustion glass manufacturing systems and methods include a melter having a floor, a roof, a wall structure connecting the floor and roof, and one or more submerged combustion burners mounted in the floor, roof, and/or wall structure discharging combustion products including water vapor under a level of material being melted in the melter and create turbulent conditions in the material. The floor, roof, or wall structure may include fluid-cooled refractory material and an optional metallic external shell, or the metallic shell may include coolant passages. One or more conduits drain water condensed from the water vapor from regions of refractory material substantially saturated with the water, and/or from burner supports.
