Crown Sheets And Stays Patents (Class 122/496)
  • Patent number: 8393304
    Abstract: A method of supporting walls of a hanging furnace of a thermal power boiler, in which method, the walls, being formed of vertical water tubes, are supported horizontally at least by means of buckstays, and vertical pillars, located outside the buckstays, are attached to the ground or the foundations of a boiler building. The method includes attaching beams to the outer surface of the water tube walls, parallel with the vertical water tubes of the walls. Buckstays are attached to the outer surface of the beams. The buckstays are positioned substantially perpendicular to the vertical water tubes of the walls. At least two of the walls, located on opposite sides of the furnace, are connected to the vertical pillars by means of the beams and by an attachment connected directly to the beams and to the pillars, in such a way that pressure loads directed perpendicularly to the water tube walls are transferred by means of the vertical pillars to at least one rigid plane surrounding the boiler.

  • Publication number: 20020040691
    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.

  • Patent number: 5799623
    Abstract: An improved means for mounting and supporting the helical feedstock coil within a pyrolysis furnace, by providing vertical support members which have an internal passageway that allows for coolant to be passed through, thus reducing the temperature of said support members and enabling the use of less expensive structural material and fabrication technique with resulting cost savings and enhanced reliability and useful life of the tube supports and furnace.
