Abstract
An asphalt plant is provided with a system for containing noxious and nuisance gases and fumes generated therein. The system includes a substantially air tight casing encircling an slat conveyor of the plant, a substantially air tight elevator chute having a substantially air tight connection to each of a drum dryer/mixer and the casing, a batcher chute having a substantially air tight connection to each of the casing and a batcher of the plant, a substantially air tight seal between the batcher and a silo of the plant, and a bypass duct bypassing the seal between the batcher and the silo such that a negative pressure created in the drum dryer/mixer by a power exhaust of the plant is distributed substantially throughout various components of the plant as the batcher and the silo contain sufficient asphalt material being processed by the plant such that air and other gases and fumes contained within the plant are prevented from escaping directly into the ambient atmosphere.
