A submerged combustion melting system includes a furnace including a tank with a floor, a roof, a perimeter wall, and an interior, and burners to melt glass feedstock into molten glass, a batch inlet, a molten glass outlet, and an exhaust outlet. An exhaust system is in fluid communication with the interior of the tank, and includes a flue in fluid communication with the exhaust outlet. A refractory-lined hood may be in fluid communication with the flue, which may be fluid-cooled including fluid-cooled perimeter panels and lower and upper baffles. The hood may include a protrusion that protrudes into a downstream horizontal exhaust path and has an excurvate upper surface to streamline flow of exhaust gas through the hood to prevent gas recirculation and formation of condensate piles in the hood. 1. A submerged combustion melting system , comprising: 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, 'a submerged combustion melting furnace, 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,', '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., 'an exhaust system in fluid communication with the interior of the tank, and including2. The system of claim 1 , wherein the fluid-cooled flue extends upwardly from the roof ...
