  • Sootblower lance port with leak resistant cardon joint
    Patent number: 6581549
    Abstract: A cardon joint is provided for mounting in a wall of a boiler to accommodate a sootblower lance and to allow the lance to be manipulated with respect to the boiler wall. The cardon joint includes a wall box having a central opening. An outer ball having a substantially spherical outer surface and a central bore is mounted for axial rotation about a first axis within the central opening of the wall box. An inner ball having a substantially spherical outer surface and a central bore is mounted for axial rotation about a second axis within the central bore of the outer ball. The first and second axes are mutually orthogonal and the central bore of the inner ball is sized to accommodate the lance of a sootblower. As the lance is manipulated to clean an opposite wall of the boiler, the inner and outer balls rotate about their axes to accommodate the manipulation.
