Definitions

  • the sizes of tubes, their material, diameter, wall thickness, number and arrangement are based upon temperature and pressure for service, according to applicable boiler design codes, such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section I, or equivalent other codes as required by law.
  • ASME American Society of Mechanical Engineers
  • Required heat transfer characteristics, pressure drop, circulation ratios, spot absorption rates, mass flow rates of the working fluid within the tubes, etc. are also important parameters which must be considered.
  • applicable seismic loads and design codes are also considered.
  • the heat exchanger includes a structural support framework in the shape of a rectangular parallelepiped having a top, a bottom and opposing lengthwise sides surrounding the heat exchanger for bottom support thereof.
  • the top of the structural support framework is comprised of two lateral beams intersecting the upper one of the pair of parallel spaced beams extending along each lengthwise side.
  • the two lateral beams are located above the heat exchanger and provide a means by which the heat exchanger and the structural support framework can be lifted for placement at a desired location.
  • FIG. 1 is a perspective view of the heat exchanger which is shown, for clarity, without the structural support framework of the present invention
  • the side walls 12 and roof portion 14 comprise evaporative or boiler heating surface. If the heat exchanger 10 is used to provide superheated steam, and as will be appreciated by those skilled in the art, some of the heating surface will have to be evaporative surface and other portions will have to be superheater surface.
  • the side walls 12 are evaporative or boiler surface, and may be provided with inlet headers 18 and outlet headers 20. The steam-water mixture generated in tubes forming the side walls 12 is collected in the outlet headers 20 which also serve as a mix point to even out temperature imbalances which may exist in the steam-water mixture.
  • Stubs 22 on the outlet headers 20 are int ⁇ rconn ⁇ ct ⁇ d via risers (not shown) to stubs 26 on upper portions of each of the vertical steam/water separators 16.
  • the vertical steam/water separators 16 operate in known fashion (see U.S. Patent No. 6,336,429 to Wiener et al.), separating the steam from the steam-water mixture. If the heat exchanger 10 is designed for saturated steam production, steam outlet connections (not shown) from the top portions of each of the separators 16 convey the steam to its downstream location and use. If the heat exchanger 10 is designed to produce superheated steam, the steam is conveyed from the separators 16 to superheater surfaces for further heating and eventual collection and conveyance to its downstream location and use.
  • the headers 36 which are part of the upper and lower structural members 32, are interconnected to one another by an arrangement of heating surface 38 which extends between and is fluidically connected to the upper and lower headers 36.
  • the heating surface 38 is up-flowing evaporative surface, comprised of tubes.
  • Tube stubs 40 provide connections for risers (not shown) which convey the steam-water mixture to the tube stubs 26 on the separators 16 as hereinbefore described.
