Definitions

  • the tube coils have to be maintained by supports. It is known to use a sliding connection with supports allowing differential movements between the tubes and the supports. The drawback of this sliding connection is that gaps and wearing associated therewith may occur.
  • an object of the present invention is to provide a boiler having a fluidized bed heat exchanger as to solve the above-described problems.
  • a boiler comprising a fluidized bed heat exchanger, the heat exchanger including a plurality of tubes forming a tube bundle, each tube following a vertical boustrophedon path, the tubes being supported by at least two vertical supporting devices, typically at least two separate vertical supporting devices, placed on both sides of the tube bundle.
  • every vertical supporting device comprises at least two vertical supports for fixing the tubes, typically at least two separate vertical supports.
  • the fixation of the tubes on the vertical supports prevents local vibrations and possible abrasions resulting therefrom.
  • Using at least two supports by device makes it possible to split the amount of efforts.
  • the boustrophedon path of each tube can comprise horizontal portions, two consecutive horizontal portions being linked together by a vertical portion thus forming a bend between the horizontal portions.
  • One supporting device can be located on the left side of the tube bundle and one supporting device can be located on the right side of the tube bundle.
  • the vertical supports can be vertical tubes.
  • each supporting device at least one horizontal portion - preferably each horizontal portion - of each tube of the heat exchanger is preferably fixed to only one vertical support of the supporting device.
  • two consecutive horizontal portions of at least one tube - preferably each tube - of the heat exchanger are preferably not fixed to the same vertical support of the supporting device.
  • each supporting device two consecutive horizontal portions of at least one tube - preferably each tube - of the heat exchanger are preferably not fixed to the same vertical support of the supporting device.
  • each tube of the heat exchanger is preferably fixed to only one vertical support of the supporting device and, for each supporting device, two consecutive horizontal portions of each tube of the heat exchanger are preferably not fixed to the same vertical support of the supporting device.
  • the boiler can comprise a furnace in which combustion of solid particles is sustained and the fluidized bed heat exchanger can be placed outside the furnace.
  • FIG. 1 illustrates a boiler that includes a furnace 1 in which combustion of solid particles is sustained.
  • the top of the furnace 1 is connected to a separator member 2 via an extraction duct 12 which conveys the flue gases and the recycled particles.
  • the separator member 2 e.g. a cyclone, delivers the gas to a flue duct 20 leading off from its top, and it delivers the particles to a recycling duct 23 which leads into an external dense fluidized bed 3 that is placed outside the furnace 1.
  • the recycling duct 23 is generally provided with a siphon and with lagging.
  • the external bed 3 is provided with a first heat exchanger 3A, and which, in this example, is in the form of a nest of tubes that zigzag in vertical planes, following a boustrophedon path, so that the long tube segments are preferably horizontal.
  • the first heat exchanger 3A is fed with a coolant fluid, e.g. water, via an inlet 39.
  • the outlet 30 of the heat exchanger 3A can be connected to a second heat exchanger 3B which can be located in the furnace 1.
  • the heat exchanger 3A includes a plurality of tubes 7 (four tubes in this example) zigzagging in a vertical plane.
  • the tubes 7 can be of a square or circular cross-section.
  • the serpentine tubes 7 follow each a boustrophedon path.
  • Boustrophedon is a kind of bi-directional text, mostly seen in ancient manuscripts and other inscriptions. Every other line of writing is flipped or reversed, with reversed letters. Rather than going left-to-right as in modern English, or right-to-left as in Arabic and Hebrew, alternate lines in boustrophedon must be read in opposite directions. The name "boustrophedon" is taken from the Greek language.
  • Two or more distinct supporting devices 41,42 separated by an empty space realize the support of the fluidized bed heat exchangers bundle tubes.
  • One device 41 is located on the left side of the exchanger and the other device 42 is located on the right side of the exchanger.
  • Each device 41,42 comprises at least two vertical supports 411,412;421,422 separated by an empty space and which are two close hanger tubes along with alternately welded interference clamps supports, which position can be adapted according to mechanical calculation results.
  • the hanger tubes 411,412;421,422 may be cooled, as is the case in the High Temperature Superheater (HTS) bundles.
  • the hanger tubes 411,412;421,422 may be uncooled, as is the case in the Intermediate Temperature Superheater (ITS) bundles.
  • HTS High Temperature Superheater
  • ITS Intermediate Temperature Superheater
  • FIG 4 illustrates the fixation points 6 between the tubes 7 and the vertical tubes 411,412,421,422.
  • the first supporting device 41 comprises two vertical supports 411,412, i.e. one left support 411 and one right support 412.
  • the second supporting device 42 comprises two vertical supports 421,422, i.e. one left support 421 and one right support 422.
  • the tube bundle comprises five tubes 71 to 75.
  • the tubes 71,72,73,74,75 follow a boustrophedon path including four bends A,B,C,D.
  • the number of tubes and the number of bends are given by way of example, and a person skilled in the art can choose a different number of tubes and bends.
  • tube 71 i.e. a tube numbered N
  • this tube 71 is connected before the bend A to the right support 412 of the first supporting device 41 and after the bend A to the left support 411 of the first supporting device 41.
  • the tube 71 is then connected before the bend B to the left support 421 of the second supporting device 42 and after the bend B to the right support 422 of the second supporting device 42.
  • the same connection mode is then repeated: the tube 71 is connected before the bend C to the right support 412 of the first supporting device 41 and after the bend C to the left support 411 of the first supporting device 41.
  • the tube 71 is then connected before the bend D to the left support 421 of the second supporting device 42 and after the bend D to the right support 422 of the second supporting device 42.
  • the tubes 72 and 74 are connected in the opposite way, i.e. a connection of a tube N to the right support 412 of the first supporting device 41 is replaced for a tube N+1 by a connection to the left support 411 of the first supporting device 41 and vice versa.
  • a connection of a tube N to the right support 422 of the second supporting device 42 is replaced for a tube N+1 by a connection to the left support 421 of the second supporting device 41 and vice versa.
  • a second embodiment is shown on Figure 8 .
  • all the tubes 71 to 75 are connected before the bend A to the right support 412 of the first supporting device 41.
  • all the tubes 71 to 75 are connected after the bend A to the left support 411 of the first supporting device 41.
  • all the tubes 71 to 75 are connected before the bend B and after the bend A to the right support 422 of the second supporting device 42.
  • all the tubes 71 to 75 are connected after the bend B to the left support 421 of the second supporting device 42.
  • each horizontal portion of an exchanger tube is fixed to only one vertical tube of the supporting device, and 2) for each supporting device, and preferably for both supporting devices, two consecutive horizontal portions of an exchanger tube (i.e. an horizontal portion of the tube placed before one bend of the boustrophedon path and the horizontal portion placed after the bend) are fixed to a different vertical tube of the supporting device.
