Abstract
A drive assembly for a sootblower which provides a non-constant rate of rotational motors of the lance tube through the use of non-circular gears in the drive assembly. The drive assembly is used to provide a uniform or near uniform rate of progression of a jet of cleaning medium ejected from the lance tube along a surface to be cleaned.
