Definitions

  • the present invention relates to a heat exchange panel with vertical tubes forming loops between an inlet and an outlet by which they are suspended from a rigid structure, and intended to be in contact by their outer surface with gases loaded with soot, in which the tubes of the central part are joined together by fins. It also extends to methods of manufacturing such a panel.
  • the document FR-A-1 418 565 describes a panel of heat exchange tubes, of small spacing, and which are all joined together by fins.
  • the welds of the fins on the end tubes are also subjected to stresses due to the temperature differences between the tubes and to the weight of the tubes in the central part, leading to risks of cracking and leakage.
  • the object of the present invention is to provide a heat exchange panel with soot-laden gases which is easy to clean off soot deposits, but which is at the same time easy and mechanizable to manufacture and does not exhibit any brittleness. of its welds.
  • the heat exchange panel according to the invention is characterized in that all of its tubes are spaced from each other by a step slightly greater than their diameter, and in that the end tubes connected directly to the suspension structure are joined together and with the nearest adjacent tube by low-rise members welded on either side to the neighboring tubes at a level below that of the upper loops of the panel, and are joined together and with the tube adjacent below the fastening members.
  • two separate circuits of tubes with looped ends are formed separately, they are inserted one into the other, vertical elements are placed between the adjacent tubes, then these elements with adjacent tubes using a translational welding machine along the tubes.
  • this panel sections of straight tubes are assembled side by side, fins are formed between these tubes, then connection loops are welded to their ends.
  • the heat exchange panel consists of two tubes 1, 2 close to each other, and whose convolutions are nested one inside the other.
  • the spacing of these tubes has been exaggerated for clarity. They are suspended by their inlet 1A and outlet 1B ends from fixed structures 3 and 4.
  • their pitch spacing of their axes
  • These tubes form loops 5, 6, 7, 8 at their lower part and loops 9, 10, 11 at their upper part.
  • Tubes 1 and 2 are connected to each other over most of their length by a fin 12 .
  • the two end sections and the adjacent section are connected by means of fastening elements 14, 15, welded to the adjacent tubes according to generators.
  • fastening elements 14, 15, welded to the adjacent tubes according to generators are represented on a larger scale on the Figures 2 and 3, corresponding to detail II of Figure 1.
  • the element 14 connects the end tube sections 21 and 22, and the element 15 the section 22 with the adjacent section 23 of the panel.
  • These panels can be double as shown in Figure 1, but they can be single, triple or quadruple.
  • junction fin elements 26, 27 stop a little below the elements 14, 15.
  • the upper zone of the fins has a slot such as 28, ending in a circular hole 29 in order to avoid a crack propagation initiation. In this way, the stresses due to differential expansion are transmitted by the parts 14, 15 and dissipate throughout the panel.
  • FIG. 4 shows a section through a horizontal plane in the upper part of the panel, above the level of the hollow securing elements 14, 15.
  • the sections of tubes 21, 22 and 23 are separated from each other, while the sections 23, 24, 30, and so on, are connected by a fin.
  • Figures 6, 7 and 8 show three variants of the constitution of the junction fin between the sections of tubes. They correspond to a section along the axis VI-VI of FIG. 1.
  • FIG. 6 represents a junction fin formed by vertical plates 34, 35, attached and welded on each side to the tubes 31, 32, 33 according to weld lines such as 36, 37.
  • the tubes may already have their loops d end and have been placed one inside the other, or the end loops can be welded to the ends of the tube sections after the fins have been fitted; in this case the welding machine moves along the axes tubes.
  • FIG. 7 represents junction fins 38, 39 formed by depositing molten metal between the adjacent tube sections 31, 32, 33, by a fixed automatic machine in which the tubes pass. The end loops are subsequently welded to the ends of the tube sections.
  • FIG. 8 represents junction fins 40, 41 formed by welding tubes 31, 32, 33 provided with ribs in a diametral plane. Also in this case, the ribs are welded together by a stationary machine. The end loops are welded later.
  • the heat exchange panel according to the invention applies more particularly to heat recovery boilers by incineration of black stationery liquor or household waste, but it is suitable in all cases where an exchange must be carried out of heat between a fluid to be heated or vaporized circulating inside the tubes and gases or vapors laden with solid dust circulating around them.
