  • Open beam sootblower
    Patent number: 5549079
    Abstract: A retractable sootblower having an open frame. The frame includes an inboard end wall, an outboard end wall and a pair of opposingly positioned side panels. The side panels are seamless and mounted to interconnect the inboard and outboard end walls together. The side panels cooperating with the end walls to generally define a rectangularly shaped structure which encloses the carriage and lance tube of the sootblower. The generally open top and bottom of the frame allows for substantially unobstructed access from above and below to the carriage and lance tube. The sootblower also includes a dry lance hub which eliminates various problems associated with lubricant deterioration.
    Type: Grant

  • Open beam sootblower
    Patent number: 5365890
    Abstract: A retractable sootblower having a substantially open frame. The frame includes an inboard end wall, an outboard end wall and a pair of opposingly positioned side panels. The side panels are seamless and mounted to interconnect the inboard end and outboard end walls together. At least one truss extends between the side panels. The side panels cooperating with the inboard and outboard end walls to generally define a rectangularly shaped box for enclosing the carriage and lance tube of the sootblower. This box has a generally open top and bottom which provides substantially unobstructed access from above and below to the carriage and lance tube. The sootblower also includes a mechanism for adjusting the backlash between the drive rack and gear.
