Abstract
A sootblower is provided having a multidirectional cleaning range for directing a cleaning medium against heated surfaces in a heat exchanger. The sootblower includes a rotatable lance tube that is selectively advanced and withdrawn along a longitudinal axis from an interior volume of the heat exchanger. The lance tube includes an articulating wrist coupled to a nozzle for projecting the cleaning medium in multi-directions onto the heated surfaces when the lance tube is advanced into the heat exchanger. The nozzle is pivotable about the longitudinal axis and about a second axis transverse to the longitudinal axis.
