Abstract
Apparatus for cleaning air ports in a chemical recovery furnace comprises an elongated cleaning rod provided with a tip on one end adapted to be inserted through an air port with a ramming motion to dislodge residual build-up. The cleaning tip is substantially smaller than the air port. Between ramming motions, the rod carrying the tip is moved a fraction of the distance around the inside edge of the air port so that successive insertions of the tip will dislodge or sever the residual material build-up.
