Abstract
A sootblower for cleaning heat exchanger surfaces in a boiler. The sootblower includes a carriage assembly supported by a frame and adapted to cause translational and rotational movement of a lance tube to insert and retract the lance tube into and out of the boiler. The lance tube includes nozzles which project a blowing medium against the heat exchanger surfaces in the boiler. A mechanism is provided to articulate the sootblower so that the angular orientation of the lance tube can be altered with respect to the heat exchanger surfaces in the boiler. The articulating mechanism permits the carriage assembly to advance and withdraw the lance tube in and out of the boiler along a different axes thereby enabling greater cleaning coverage of the heat exchanger surfaces.
