ABSTRACT:
The feed tube of a long retracting sootblower has a lance tube slidably overfitted thereon which is of an inside diameter somewhat exceeding the outside diameter of the feed tube, to provide a relatively narrow gap therebetween. The open end of the feed tube has a turbulizer mounted therein contoured to impart a helical component to the blowing fluid which blows into the lance tube from the feed tube. At a position spaced upstream from the turbulizer the wall of the feed tube is pierced with a plurality of holes equally spaced throughout its periphery. The holes provide centering jets which oppose vibration of the feed tube and prevent impacting of the same against the interior of the lance tube.
