ABSTRACT:
Removable apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum having an adjustable damper is mounted inside a wind box associated with the furnace adjacent to an air port and supplies and regulates the flow of air from the wind box to the furnace through the air port. A metal cleaning head having a cage-like configuration is pivotally mounted in a retracted, at-rest position inside the plenum above and adjacent to the air port so as not to interfere with movement of the adjustable damper.
