Abstract:
A rake-type sootblower comprising:a. an axially movable outer manifold comprising:i. an axially extending tube defining a plenum,ii. a plurality of rakes attached to said tube, said rakes each containing a plurality of sootblowing nozzles, andiii. connecting means between said tube and each of said rakes including openings in said tube providing for the flow of sootblowing media from said plenum into said rakes and out of said nozzles;b. bushing means inside of said plenum associated with each of said connecting means for isolating said connecting means from each other;c. an inner manifold extending through said plenum and through said bushing means and connected to a source of sootblowing media for providing said sootblowing media to the inside of said inner manifold;d. a hole in said inner manifold associated with each of said connecting means and rakes for the flow of sootblowing media from said inner manifold into each of said connecting means and rakes; ande. means for moving said inner manifold with respect to said outer manifold and said bushing means to selectively and alternately align each of said holes in said inner manifold with said associated connecting means to alternately provide for the flow of sootblowing media from said inner manifold into each of said connecting means and rakes.
