Abstract: A cleaning apparatus for cleaning a smelt spout of a boiler is provided. The boiler includes a boiler wall defining an outlet port for discharging molten smelt and the smelt spout is positioned with respect to the outlet port so that the molten smelt is able to flow along the smelt spout. The cleaning apparatus includes a cleaning tool having a pair of cleaning blades generally aligned with respective side walls of the smelt spout and an actuating assembly configured to move the cleaning blades from a first position to a second position. The cleaning blades each engage the respective side walls of the smelt spout to dislodge hardened smelt deposits therefrom when in the cleaning blades are in the second position.

Abstract: A port rodder assembly for a recovery boiler includes a duct affixed to and in fluid communication with an air port of the boiler, having a hollow interior, and an air inlet opening. A cutting head is slidably mounted within the duct adjacent to the air port and is adapted to clean the air port. An actuator selectively advances the cutting head though the air port to clean the air port. A wing is pivotally mounted within the duct. The wing interacts with the air inlet opening to control the flow of air through the duct and into the air port and is shaped such that incoming air flows smoothly through the duct to the air port.
