OSTI ID:7345315
Apparatus is disclosed for attachment adjacent to an open end of a rotary furnace, having a first effluent furnace gas exhaust duct projecting into the furnace and a dust collecting hood adjacent to the furnace opening. A pressurized air duct plenum having a plurality of air jet holes directs a curtain of air across the furnace open end, and a receiving air duct plenum having a plurality of openings collects the air curtain for exhausting via a filter system. The hot effluent furnace gas is passed through a gas-to-gas heat exchanger and to the aforementioned filter system.
