Method and apparatus for prevention of clogging of exhaust systems

摘要

A method and apparatus is disclosed for prevention of clogging of exhaust systems, especially the exhaust hoods and ducts above fused salt baths onto which salts splatter as they are being added by spraying from aqueous solutions. A fluid tight jacket surrounds a portion of the exhaust pipe and hood and a cooling fluid, preferably the aqueous solution of the salt being added is flowed through the jacket. This will condense the water of the solvent onto the inside of the hood and duct dissolving and washing away any splattered salt.
