Description of the source (including control equipm ent). Please see the attachments for source or process flow diagram: The V-1 Furnace is a gas-fired, oxy-fuel furnace which supplies energy to the mixed glass batch via a combination of radiant, conductive and convective heating from a set of side wall burners fired with natural gas and oxygen whose hot combustion products flow over the top of the batch. The furnace is equipped with a dry electrostatic precipitator (DEP) to control particulate emissionsthat are created from batch charging and glass volatiles that “boil” from the surface of the molten glass condensing in the exhaust stream forming small diameter particulate matter. The V-1 Furnace exhausts to a single, ground-mounted exhaust stack. The stack is round and 36 inches in diameter. The two stack test ports are 4 inches in diameter located approximately 40 feet above ground level. The Owens Corning facility in Waxahachie is located 3700 North Interstate 35 E in Waxahachie, Texas. Industry/SCC/NAIS 327993
