1. A submerged combustion melting system, comprising:
a submerged combustion melting furnace, including:
a tank including a floor, a roof, a perimeter wall extending between the floor and the roof, and an interior,
submerged combustion melting burners extending through the tank to melt glass feedstock into molten glass in the interior of the tank,
a batch inlet at an upstream end of the tank,
a molten glass outlet at a downstream end of the tank, and
an exhaust outlet; and
an exhaust system in fluid communication with the interior of the tank, and including:
a fluid-cooled flue in fluid communication with the exhaust outlet, and including fluid-cooled perimeter panels,
a refractory-lined hood in fluid communication with, and extending to a hood outlet from, the fluid-cooled flue, and including refractory-lined walls and a dilution air duct inlet, wherein the refractory-lined hood includes a vertical portion configured to extend upwardly from the fluid-cooled flue and a horizontal portion configured to extend away from the vertical portion and to the hood outlet,
a dilution air input duct having an outlet in fluid communication with the dilution air duct inlet of the refractory-lined hood, and
non-cooled, non-refractory outlet conduit extending away from the refractory-lined hood.
