Apparatus for cleaning air ports in a chemical recovery furnace includes a plurality of rods, each having a cleaning tip thereon, mounted on a wind box adjacent the furnace. The rods are longitudinally slidable to insert the cleaning tips into the air ports, and are rotatable about an axis perpendicular to the longitudinal axis of the rods so as to index the cleaning tips to a new point of insertion into the air port opening. An air cylinder actuator is employed to insert the cleaning tips into the openings in a ramming motion to dislodge residual buildup in the air port opening, retract the cleaning tips from the air port openings, and index the tips to a new point of insertion. Successive invocation of the actuating means results in removal of residual buildup along the entire length of the air port openings.
