ABSTRACT:
An improved sootblower nozzle assembly adapted for cleaning heat exchange surfaces or the like comprising a lance tube having at least one nozzle affixed thereon. The nozzle comprises a tubular body formed with a centrally extending discharge throat and a plurality of second apertures arranged around the central discharge throat. A pressurized fluid blowing medium introduced into the lance tube during a cleaning cycle is discharged from the nozzle in the form of a composite stream including a central directionally oriented stream surrounded by a plurality of secondary streams forming an encircling protected shroud to maintain the integrity of the central stream and to increase its impact pressure on the surfaces to be cleaned.
