摘要： A smelt spout cleaner apparatus includes a cleaning head insertable into a smelt spout and movable in a substantially linear path along the smelt spout for thoroughly cleaning the spout. The cleaning head is mounted on one end of a substantially horizontal beam, the opposite end of which is supported in cantilever fashion to a support base which is selectably movable. The support base includes means for longitudinally translating the beam and causing the cleaning head to move in a linear path along the length of the smelt spout.

摘要： 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.

摘要： Damper apparatus for air ports of a chemical recovery furnace is mounted on a removable windbox faceplate. Damper blades extend from cantilevered arms pivoted at the forward side of the faceplate, with the damper blades being otherwise unsupported, i.e., they are not confined to travel in tracks within the windbox. Rather, a spring or counterweight urges the damper blades against the air port opening whereby the whole mechanism is free for removal as a unit with the faceplate. Cooperatively operable air port cleaning apparatus is also mounted on the faceplate.

摘要： Apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum having an adjustable damper mounted inside a wind box associated with the furnace adjacent to the air port supplies and regulates the flow of air from the wind box to the furnace through the air port. A metal cleaning head adapted for rotatable insertion into the air port for cleaning excrescent material from the peripheral edges of the air port without blocking air flow through the port is pivotally mounted in a retracted, at-rest position adjacent to and above the air port so as not to interfere with movement of the adjustable damper. During a cleaning cycle, the damper is moved to a retracted position on the floor of the plenum so as not to interfere with the moving cleaning head. A short stroke, double articulated damper positioning mechanism facilitates movement of the damper blade in limited space.

摘要： Removable apparatus for regulating air flow through an air port in a chemical recovery furnace. A plenum mounted adjacent an air port inside a wind box associated with the furnace supplies combustion air from the wind box to the furnace through the air port, and an adjustable damper mounted inside the plenum regulates the velocity and quantity of air flowing through the plenum. An access port in the plenum allows viewing of the air port opening through the plenum. An actuating mechanism withdraws the damper from the field of view to a retracted position wherein the damper depends from the top of the plenum chamber spaced apart from the air port opening. For airflow damping, the actuating mechanism moves the retracted damper toward the air port opening until the damper is adjacent to the opening; then a positioning mechanism pivots the damper to a predetermined position in the air stream adjacent the opening. The damper positioning mechanism comprises a spring loaded cylinder that holds the damper by spring tension, when retracted, above the flow of air through the plenum chamber. Upon further compression of the cylinder by the actuating mechanism, the reduced length of the compressed cylinder forces the damper downward into the air stream. When the actuating mechanism is reversed, the spring tension of the compressed cylinder pulls the damper upward to the retracted position.

摘要： Improved air port castings are employed in a recovery boiler, eliminating the use of a crotch plate in a membrane/tube type boiler. The casting extends over the exposed portion where the membrane begins again at an air port, providing a sacrificial member that is replaceable. An upper mounting bolt is employed, but no lower bolt is required, making replacement of the casting simpler. A damper guide is formed as an integral portion of the air port casting.
