Definitions

  • the present invention relates to a heat exchanger, in particular a heat recovery unit, in particular a heat recovery unit for the flue gases from a hearth of a boiler and, in particular, from a gas boiler, comprising tubes swept by smoke and traversed by a heat transfer liquid which is generally water.
  • recuperator There are already known multiple embodiments of heat exchangers which applied to the fumes are called “smoke recuperator”. These recuperators are generally constituted by a set of straight tubes, the ends of which are connected to a respective manifold ensuring the distribution of the heat transfer fluid and its recovery.
  • the tubes are arranged perpendicular to the direction of passage of the fumes and staggered staggered so that the gas streams can lick the tubes in the most efficient manner in terms of the efficiency of the exchange.
  • the object of the present invention is to remedy these drawbacks and proposes to create a heat exchanger, in particular a flue gas heat recovery unit, of the above type, which is of simple construction and has high operating reliability.
  • the invention relates to a heat exchanger of the above type, characterized in that it comprises a first set of tubes, each tube of which is formed by a succession of parallel straight segments, interconnected at each end by a connecting loop, the planes passing through two successive segments being inclined alternately on one side and the other with respect to the overall plane of the tube so that the successive segments are staggered with respect to the plane of together.
  • each tube consists of a set of parallel straight segments connected by loops and only the two ends of the tube are fixed on the inlet manifold and the outlet manifold, this saves 2 (N-1) welds, N being the number of straight segments forming the tube.
  • the inlet and the outlet of the same tube are located on the same side.
  • This embodiment is a particularly advantageous solution because it simplifies the manufacture of the fact that the inlet manifold and the outlet manifold can be placed on the same side. This not only facilitates the production of the exchanger but also its integration into the flue that it must equip.
  • the inlet and the outlet of each tube are located in the extension of the respective segment.
  • This characteristic particularly facilitates the production of the tubes.
  • the exchanger is formed of a first set of tubes arranged in planes parallel to each other and perpendicular to the direction of passage of the fumes to be exhausted.
  • the exchanger comprises a second set of tubes, each tube of which is constituted by parallel segments connected by loops, the inlet and outlet of each tube are perpendicular to the direction of the segments and are located in the same side, each tube of this second set being placed in an interval formed by the homologous segments of the tubes of the first set.
  • the exchanger comprises a heat transfer inlet manifold and a heat transfer fluid departure manifold, located on the same side of the heat exchanger, these manifolds being common to the tubes of the two assemblies.
  • these manifolds are common to the two sets of tubes, it is also possible to subdivide these manifolds so as to separate the fluid passing through each set of tubes.
  • the arrival collector and the departure collector are produced by the partitioning of the same box.
  • the box forming the inlet and outlet manifolds of the heat transfer fluid is constituted by a rectangular toroid of rectangular section.
  • the invention relates to a heat exchanger and, in particular a heat recovery unit intended to exhaust combustion fumes.
  • This exchanger comprises tubes swept by the fumes. The tubes are traversed by a heat transfer liquid.
  • each tube 1 is formed by a succession of straight segments 21-30, substantially parallel to each other.
  • the ends of two successive tubes are connected by a loop 31-39.
  • the straight segments and the connecting loops form a meandering path.
  • the inlet (outlet) 40 and the outlet (inlet) 41 of the tube are located on the same side of the substantially rectangular surface occupied by the tube. In Figure 1, this is on the left side.
  • FIG. 2 shows, more precisely, the three-dimensional structure of the tube 1.
  • the tube segments 21-30 are distributed two by two in two planes P100 -P100 and P200-P200 parallel passing through the geo axis metric of the segments concerned.
  • FIG. 3 shows another exchanger tube according to the invention.
  • This tube 50 consists of rectilinear segments 51-55, substantially parallel, connected by loops 60, 61, 64, 65.
  • the inlet (outlet) of tube 50 consists of a half-loop 62 terminated by a nozzle 66 and the other outlet (inlet) of the tube 50 consists of a half-loop 63 terminated by an end piece 67 of length such that the inlet / outlet openings of the end pieces 66-67 stop substantially in a plane parallel to the segments 51-55.
  • the exchanger block consists of a first set of tubes 1 ( Figures 1 and 2) arranged parallel to each other so as to form between them intervals 100 and intervals 200 in which are housed each time a tube 50 ( Figure 3) forming the second set of recovery tubes.
  • the orientation of the tubes 50 of the second set ble is such that the axis of the segments 51, 55 is perpendicular to the axis of the segments 21-29 of the tubes 1 of the first set.
  • the return by the end pieces 66, 67 is made perpendicular to the direction of the segments 51-55 whereas, for the tubes 1 of the first set, the inlet / outlet ends are parallel to the segments, the two sets of tubes can be connected to a distribution and collection box for heat transfer fluid, located on the same side.
  • FIGS 5-7 show such a box.
  • the box is in the form of a rectangular or square ring 70 in the form of a picture frame, the sides of which bear the references 71, 72, 73, 74.
  • the sides 71 and 72 are separated from the sides 73 and 74, by a partition 75-76.
  • the group of sides 71-72 has an opening 77 and the sides 73-74 have a nozzle 78.
  • the nozzle 77 constitutes the inlet nozzle and the nozzle 78, the outlet nozzle or vice versa.
  • the cover 80 of the box 70 is shown in FIG. 7. This figure shows the connection orifices 81, 82 of the tubes 1 and the connection orifices 83, 84 of the tubes 50.
  • Figure 6 shows the shape of the box with the cover 80 and the cavities corresponding to the different sides as described above.
