Abstract
A multiple rake sootblower reciprocates over an area to clean an entire surface using a minimum of space for the sootblower stroke. An internal valving manifold and a plurality of bushings inside of a plenum isolate the rakes from each other and operate one rake at a time. This maintains the required sootblowing media pressure at the nozzles of each of the rakes. The internal valving manifold may either be reciprocated or rotated to select the desired rake.
