ABSTRACT:
A retracting lance tube for a sootblower used to clean the interior of large scale boilers featuring nozzle improvements which produce a more concentrated spray of blowing agent discharge thereby enhancing cleaning performance. According to a first embodiment of this invention, nozzles are employed at various longitudinal positions along the lance tube. According to a second embodiment, nozzles located at a particular longitudinal position are offset such that their centerlines do not intersect the lance tube centerline. Each embodiment enables the use of longer more efficient nozzles than is possible according to the prior art.
