Abstract
A method of improving control of atmospheric emission of particulate matter from the emission stack of coal combustion facilities which employ baghouse particle controllers is disclosed. The method involves injecting upstream of the baghouse a small but conditioning effective amount of ammonia gas and sulfur trioxide in sequence. When this is done, the pressure drop across the baghouse is less and the amount of particulate matter in the smoke stack emissions is reduced by significant amounts.
