ABSTRACT:
A spout for channeling smelt from a boiler through an opening in the walls of the boiler comprises a jacket having an inner wall and an outer wall. The outer wall is spaced a distance away from the inner wall and the jacket has one end insertable into the opening of the wall. The jacket defines a trough for carrying smelt from the boiler. An inlet communicates with the jacket for delivering a water flow to the jacket between the inner wall and the outer wall. An O-shaped tube communicates with the jacket at the inserted end of the jacket for receiving the water flow from between the inner wall and the outer wall of the jacket. An outlet communicates with the O-shaped tube near the inserted end for channeling the water flow from the O-shaped tube and out of the spout. A vacuum is used near the outlet for insuring a proper low pressure drop.
