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.
