Abstract
A nozzle for a sootblower is used to project a cleaning agent against the internal surfaces of a boiler for removing fireside deposit. The nozzle of the present invention incorporates a passageway having a convergent segment between its entrance end most narrow point, the throat. Extending from the throat to the nozzle's exit is an expansion chamber in which the cleaning fluid passing therein expands and drops in pressure to substantially ambient pressure. The flow streams of the jet of the cleaning agent discharged from the nozzle is essentially parallel to the center axis of the nozzle. Additionally, the nozzles can be mounted diametrically opposed or spaced along the longitudinal axis of the lance tube. Moreover, the nozzles mounted in a lance tube can be mounted flush with the outside surface of the lance tube, contoured to its shape. In one embodiment, a sootblower lance is provided with an expanded tip portion to reduce turbulence and pressure variations caused by inwardly protruding nozzles in the interior of the lance tube.
