Abstract
A soot blower assembly having a horizontally elongate steam supply tube disposed in cantilevered relationship and having a steam discharge opening at the free end, and a horizontally elongate steam discharge lance telescoped axially over the supply tube. The lance has a rear support hub which exteriorly surrounds the steam supply tube, and a seal-bearing arrangement is mounted within the hub for cooperation with the steam supply tube to permit the lance to move both axially and rotatably relative to the steam supply tube. The seal-bearing arrangement includes an axially elongate bearing sleeve which is mounted on the hub and has an inner bearing surface for rotative bearing engagement with the steam tube. This bearing sleeve is preferably constructed of bronze of similar bearing material, and is axially split to compensate for temperature-induced variations. A lip seal assembly cooperates between the steam supply tube and the hub axially rearwardly of the bearing sleeve for creating a sealed engagement with the periphery of the steam supply tube.
