<p>A glass melting furnace (10) that simultaneously preheats and removes volatile substances from glass making material being intro-duced into the furnace (10). The glass making material, consisting of cullet and scrap glass, is intro-duced on a shelf (68) located at a rear portion of the furnace (10). A vertically-oriented crown vent (34) is also located at the rear portion of the furnace (10). The shelf (68) is at such an elevation above the glass line (14) to allow sufficient time for the cutlet and scrap glass to be heated by the exhaust gases exit-ing through the crown vent (34). The furnace burners (44) also ox-idize the binder and other organic materials in the scrap glass. The furnace (10) also includes a crown vent support system that indepen-dently supports the refractory stack (74) such that the refractory stack (74) can be repaired or replaced while the furnace (10) is operating.</p> |
