Abstract
A boiler air port cleaner in the form of a substantially plate-like cutter reciprocated by a piston and cylinder power device and guided by a guide structure mounted on the outer wall of a boiler with the plate-like cutter cleaning slag from air ports in the inner boiler wall.
Claims7
A boiler air port cleaner comprising a rigid, one-piece plate-like cutter having a periphery corresponding with the periphery of the air port in the boiler and being slightly smaller for reciprocating movement through the air port to remove solidified slag from the periphery of the air port, an elongated actuating member rigidly attached to said cutter, rigid guide means slidably receiving said actuating member for guiding the actuating member during reciprocation and power means connected with the actuating member for rreciprocating the actuating member and cutter, said guide means including a mounting plate adapted to be mounted detachably to an outer wall of a boiler with the cutter in alignment with an adjacent air port in an inner wall of the boiler.
In combination with a recovery boiler including an outer wall and an inner wall in which the inner wall is provided with at least one air port for passage therethrough with the air port being subject to solidification of slag around the inner periphery thereof to restrict or obstruct air flow through the port, a cleaning apparatus for removing slag accumulated on the inner periphery of the air port, said apparatus comprising a rigid, one-piece plate-like cutter having an external periphery substantially the same as but slightly smallere than the internal periphery of the air port, an elongated actuating member rigidly attached to said cutter and extending through an opening in the outer wall of the boiler, rigid guide means slidably receiving said actuating member for reciprocating movement and power means connected to the actuating member and extending outwardly of the outer wall of the boiler to reciprocate the cutter in relation to the air port for removing slag and the like, said guide means including a mounting plate mounted detachably to said outer wall of the boiler.
