Definitions

  • the invention relates to so-called Circulating Fluidized Bed Furnace (CFBF) being part of a Circulating Fluidized Bed Apparatus (CFBA), which main components are:
  • US 5,840,258A discloses a design of such CFBA, wherein the CFBF and the FBHE have been integrated closely together; in other words: FBHE and CFBF have a common wall (tube wall).
  • this design provides the advantage of close (similar) temperatures in both units and thus, minimizes any thermal stresses between both units.
  • the thermal expansion of a CFBF of a height of ca. 35 to 50m may range from 0,1m to 0,3m and may cause serious stresses within the furnace walls, independently of whether the furnace is bottom supported (according to US 5,840,258A ) or top-supported (suspended), as shown in US 6,305,330B1 .
  • One further problem in this context is to properly adapt associated parts of the CFBA, for example the separator and/or the heat exchanger.
  • associated parts of the CFBA for example the separator and/or the heat exchanger.
  • special expansion joints are required to accommodate motions between associated parts.
  • EP 2 884 172 A1 relates to a circulating fluidized bed furnace comprising an outer furnace wall, to which a heat exchange chamber is friction locked to achieve the required mechanical stability of the heat exchange chamber. If further discloses that the heat exchange chamber can be mounted in a suspended manner for a separator without disclosing any further details.
  • a compact design may be realized by bringing associated units of the CFBA as close as possible or even better to fix one unit to another (as known from US 5,425,412 ), but any such friction-locked arrangement of adjacent/associated units causes serious structural problems in view of the extreme weights/loads of such units.
  • a generic heat exchanger of a CFBA has a size of for example 5x5x5m and a corresponding weight of 100.000kg in an empty state. Additional loads by the solid material transported through said heat exchanger vary strongly and may be in a range up to 100.000kg or more.
  • the furnace wall, to which the heat exchanger may be friction-locked typically a so-called tube wall, cannot withstand/compensate such high and varying loads unless constructed as a "castle-wall", being unacceptable in view of costs and the thermal conditions of a CFBA.
  • the thermal expansions/constrictions mentioned above cause further structural problems.
  • the invention now provides a technical solution for this problem and furthermore a technically relatively simple construction, by further providing at least one structural element, by which the heat exchanger is mechanically linked to the furnace wall, which structural element allows to compensate any such additional loads caused by the heat exchanger and/or the material passing there through.
  • the invention relates to a circulating fluidized bed furnace, comprising the features of claim 1.
  • the structural element "absorbs" all (additional) forces, which have not been absorbed by the furnace wall, to which the heat exchanger is fixedly secured for example by welding.
  • the first end of the structural element is fixed to the furnace wall at a vertical distance above the heat exchanger, while it is important for the second end being affixed to the heat exchanger at a horizontal distance to the furnace wall and best to a vertically extending wall of the heat exchanger, for example its outer wall, being the wall opposite to the furnace wall.
  • the structural element has at least three sections, a first section, extending from the first end of the structural element downwardly and substantially parallel to the outer furnace wall, a second section, extending from the second end of the structural element upwardly, and at least one intermediate section in-between said first and second sections.
  • the second section should extend substantially parallel to the outer furnace wall "Substantially parallel” includes a sloped orientation within technical tolerances, with an angle between furnace wall and a longitudinal axis of the structural element of at most 15°, better less than 10°, less than 5° or less than 3°.
  • the run of the structural element e.g. the rope or wire
  • the run of the structural element downwardly and parallel to the furnace wall allows to largely avoid mechanical moments to act on said rope but to stress the rope predominantly or even exclusively in its axial direction.
  • the structural element has at least three sections, a first section, extending vertically downwardly from its first end, and/or a second section, extending vertically upwardly from its second end (and insofar as well parallel to the furnace wall), and at least one intermediate section, extending in-between especially in a substantially horizontal orientation.
  • the vertical orientation of the tensile means (rope etc), parallel to the furnace wall, to which it is fixed at its first end, causes any forces to be absorbed by said rope to be forces in an axial direction of said means, i.e. in a direction, where the said rope features its highest stability.
  • Fig. 1 displays a highly schematic drawings of a furnace arrangement according to the invention.
  • Fig. 1 displays part of a circulating fluidized bed apparatus (CFBA), namely a circulating fluidized bed reactor (furnace) 10 with a particulate material inlet port 10i, an air plenum at a bottom area (symbolized by arrow 10a), a fluidized bed of particulate material above said air plenum, being part of its combustion chamber 10c, and at least one outlet port 12 at its upper part, wherein said outlet port 12 allows a mixture of gas and solid particles exhausted from the circulating fluidized bed furnace chamber 10c to flow into at least one associated separator 14 for separating solid particles from said gas, means 16 (including a non-illustrated syphon) to transfer said separated solid particles into at a circulating fluidized bed heat exchanger 20 and return means 22 to transport the solid particles back into the circulating fluidized bed furnace 10, wherein the circulating fluidized bed furnace 10 (also called a boiler), the separator 14 (also called a cyclone) and the circulating fluidized bed heat exchanger 20 (or any other type
  • a plurality of vertically extending steel support columns 30r,l extends from the ground (symbolized by foundations 32) to a plurality of spaced horizontally extending beams 34.
  • a plurality of hanger rods 36 extends downwardly from said beams 34 for supporting the furnace 10 and the separator 14 in a suspended manner.
  • the heat exchange chamber (unit) 20 (wherein heat exchange means like heat exchange tubes are symbolized by wave 20w) is friction-locked to the furnace 10 (its tube wall 10r) by welding. It derives from this that part of the right wall 10r of said circulating fluidized bed furnace 10 represents as well the left wall of said heat exchanger 20, which other walls - as well as the furnace walls - are all designed as tube walls (made of tubes in a spaced relationship with fins in between and water and/or steam flowing through said tubes).
  • the circulating fluidized bed heat exchanger 20 is further suspended by a steel rope 50, having a first end 50f, fixed to the right furnace wall 10r, and a second end 50s, fixed to the upper end section of the right wall 20r of the heat exchanger 20, i.e. at the largest possible horizontal offset to the furnace wall 10r.
  • the steel rope 50 has three sections, a first section 50fs, extending vertically downwardly from its first end 50f and parallel to the furnace wall 10r, a second section 50ss, extending vertically upwardly from its second end 50s (and insofar as well parallel to the furnace wall 10r), and one intermediate section 50is, extending in-between in a substantially horizontal orientation and insofar perpendicular to the furnace wall 10r.
  • the first rope section 50fs runs closely to the furnace wall 10r; insofar fixation means 50fm of said first rope section 50fs are displayed larger than in reality (for the purpose of a better illustration).
  • the intermediate rope section 50 is winds around a lower part of a first rotating disk (roller) 52fd, mounted to a beam 52, which extends horizontally from column 30r, at its left end (following the first rope section 50fs) and, at a distance thereto, winds around an upper part of a second roller (rotating disk) 52sd (followed by the second rope section 50ss).
  • Said rope 50 not only fulfils the function of a structural element to support the heat exchanger 20 in a suspended manner, but provides the advantage, that the strain on the first section 50fs of said rope 50 is predominantly parallel to the right tube wall 10r and underdoes predominantly (nearly exclusively) only vertically downwardly directed tensile forces.
  • Fig. 1 further displays an optional, but favorable feature of the invention, namely constant load hangers (only one of which is shown in Fig. 1 ) and identified by numeral 54.
  • Said constant load hangers 54 which can be for example constant load springs and/or constant load coils, are attached with their upper ends to said beam 52 and with their lower ends to the ceiling (upper tube wall 20u) of the heat exchanger 20 and are able to relieve said rope 50.
  • the suspended construction of said furnace 10 allows to follow the thermal expansions of the respective construction elements and avoids mechanical forces, thermo-mechanical forces and/or moments between adjacent construction parts.
  • the common section of tube wall 10r brings the temperatures within heat exchanger 20 and furnace 10 into closer conformity and thus minimizes any thermal and mechanical stresses between these units of the CFBA, avoiding special expansion joints in between to great extent.
