  • Articulating water monitor cleaning device
    Patent number: 6655397
    Abstract: An articulating water monitor-cleaning device for cleaning internal surfaces of large-scale combustion devices. The device is mounted to the exterior of a wall of a combustion device and positions a water spray lance to direct a stream of water against internal surfaces over a range of position. Pairs of orthogonally oriented four-bar linkage assemblies are provided, each having rotary actuators. The relative position between a pair of joints affixed to the lance tube allows the position of the lance to be set over a range of positions.
    Type: Grant

  • Method and apparatus for constant progression of a cleaning jet across heated surfaces
    Patent number: 5437295
    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.
