Abstract
A method and apparatus for cleaning heated surfaces with substantially constant progression of a jet cleaning medium. The invention monitors the rotational and translational position of the lance tube and is programmed with a schedule of lance tube rotation rates and blowing medium discharge rates for the specific configuration of the heated surfaces. Based upon the rotational and translational position of the lance tube and the distance the jet travels before impinging upon the heated surfaces, the rate of rotation of the lance tube is varied throughout every rotation to maintain substantially constant progress of the jet across the heated surfaces.
