ABSTRACT OF THE DISCLOSURE The apparatus disclosed herein is designed for removing solid deposits, which interfere with heat transfer, from the surface of the basket section in an air preheater. In one type of regenerative air preheater, the basket section rotates around a hub inside a chamber. A threaded rod is installed in the chamber parallel to the basket section, at a distance sufficient to allow clearance of the carriage assembly and jet nozzle, or nozzles. The carriage assembly is attached to the rod by a threaded drive block and a motor drive, which is controlled by an electronic programmer, rotates the threaded rod to drive the carriage incrementally along the rod and beam. As the basket section rotates, a high pressure water jet, or jets, is directed through the nozzle to wash the solid deposits off the basket section. 28,355-F
