ABSTRACT:
A nozzle for the spraying of black liquor in a recovery boiler has discharge orifice inserts that can be removed and replaced with other inserts, to provide variable spray patterns, by changing the size and/or shape of the orifice of the nozzle, without requiring replacement of the entire nozzle body, to enable fine tuning of the atomization of the spray.
