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.
