1. A submerged combustion glass manufacturing system comprising:

  • a melter comprising a floor, a roof, a wall structure connecting the floor and roof, an exhaust passage through the roof, and at least one baffle plate extending from the roof and configured to extend at least partially between the exhaust passage and material being melted in the melter;

    one or more submerged combustion burners mounted in the floor and/or wall structure, the submerged combustion burners configured to discharge combustion products under a level of material being melted in the melter and create turbulent conditions in substantially all of the material; and

    an exhaust structure fluidly connecting only the exhaust passage with an exhaust stack, the exhaust structure comprising a barrier preventing exhaust material from contacting the atmosphere, the barrier defining an exhaust chamber having an interior surface, the exhaust chamber having a cross-sectional area greater than that of the exhaust stack but less than the melter, the barrier configured to maintain temperature and pressure in the exhaust structure at values sufficient to substantially prevent condensation of exhaust material on the interior surface.
