  • Smelt spout for recovery boiler
    Patent number: 4011047
    Abstract: A non water cooled smelt spout for a pulp mill chemical recovery furnace. The spout is constructed from insulating and refractory material contained in a metal trough and is provided with a steam jet immediately adjacent the bottom free end of the spout. The jet impairs the formation of slag on the bottom of the trough and disintegrates the smelt stream issuing from the spout. Preferably the steam passage leading to the jet or nozzle extends along the bottom of the spout whereby the steam forming the jet also cools the bottom wall.
