ABSTRACT:
Apparatus for cleaning air ports in a chemical recovery furnace includes a face plate removably received in a frame secured to the outer wall of the wind box associated with the furnace. The face plate pivotally carries a plurality of tubes which sealingly receive rods adapted to slide in the tubes toward and away from the air ports on the interior furnace or firebox wall. An actuating cylinder moves the rods toward the air port openings, while a reciprocating mechanism rotates the aforementioned tubes causing cleaning tips on the rod ends to enter the air port openings and clean char buildup along the edges thereof.
