  • Apparatus and method for cleaning smelt spouts and smelt discharge openings of a chemicals recovery furnace or boiler
    Patent number: 11293636
    Abstract: An apparatus comprising a cleaning rod driven in reciprocating, axial extension (y) and retraction (x) movements upon cleaning a smelt discharge opening of a chemicals recovery boiler, wherein a linear actuator is controllable for driving the cleaning rod in the axial movements. A pivot actuation means is controllable for pivoting the cleaning rod about an axis (S) upon cleaning a smelt spout associated with the smelt discharge opening, wherein one or more sensors are arranged to provide control basis for correlation of the axial movements (x; y) with the change in pivot angle (?) during pivoting of the cleaning rod. A method to be performed in use of the apparatus is likewise disclosed.
