  • Welded bracket for supporting superheat and reheat assembly tubing on steam cooled hanger tubes
    Patent number: 5943985
    Abstract: Apparatus which may be a part of various systems including piping systems and fluidized bed systems. The apparatus that holds one tube with respect to another tube includes a body that has a first cylindrical section shaped portion and a second cylindrical section shaped portion. Each of the cylindrical section shaped portions has an angular extent that is generally concave. The angular extent of the first cylindrical section shaped portion and the angular extent of the second cylindrical section shaped portion each have an axis and the axis of the first cylindrical section shaped portion may be spaced from the axis of the second cylindrical section shaped portion. Some embodiments of the invention have cylindrical section shaped portions that have an angular extent that is no greater than 180 degrees. The axis of the first cylindrical section shaped portion may be perpendicular to the second cylindrical section shaped portion.

  • Fluidized bed with improved nozzle construction
    Patent number: 5575086
    Abstract: A fluidized bed system which includes a housing and a floor comprising a plurality of generally parallel tubes joined by fins intermediate adjacent tubes. A plurality of nozzle assemblies extend generally vertically in mutually parallel relationship from the floor. Each of the nozzle assemblies includes a generally cylindrical body having a centerline disposed in generally perpendicular relationship to the floor and each of the bodies includes a plurality of heads extending generally radially therefrom at an axial extremity thereof remote from the floor. In some embodiments of the invention each of the heads are uniformly spaced around the circumferential extent of each of the bodies and each of the heads is generally cylindrical and has a centerline. Each of the centerlines of the heads may be disposed at an angle with respect to a horizontal plane and the angle may be approximately twenty degrees.

  • Apparatus for supporting a perforated plate air distributor for a fluidized bed
    Patent number: 4300458
    Abstract: Apparatus for supporting a perforated plate (24) air distributor for a fluidized bed combustion boiler. The plate (24) is supported (26) around its entire periphery, and at given points (42) within its periphery, in such a manner that it is free to expand due to thermal growth in a horizontal direction, while still being capable of supporting a vertical load (12) without sagging, buckling, or being subject to failure.
