Definitions

  • the present invention relates to a boiler with variously-shaped heat exchange elements.
  • a heat exchanger is a device for changing the temperature of a fluid (“working fluid”) by forcing a heat exchange with another fluid (“exchange fluid”) a large amount of which is available at a temperature sufficient to bring the working fluid to the required temperature.
  • working fluid a fluid
  • exchange fluid another fluid
  • a boiler comprises a heat exchanger fitted with a burner that can generate the exchange fluid (combustion fumes and hot air) within a combustion chamber, in order to heat water or air (the working fluid) within the boiler casing or body.
  • Each of these exchanger modules is formed by a pair of basic elements, which are reciprocally connected in a facing position so as to form a single block.
  • the object of the present invention is to obtain a boiler that can withstand higher pressures than a traditional heat exchanger.
  • a boiler including a burner, a heat exchanger adapted to raise the temperature of a working fluid through heat exchange with an exchange fluid, including a plurality of heat exchanger modules placed side by side in order to define a combustion chamber within which said burner for the generation of said exchange fluid is inserted, exchange walls for the passage of said exchange fluid, an ejection chamber for said exchange fluid fitted with a discharge flue, and a substantially parallelepiped casing adapted to be filled with working fluid, characterised in that said casing has side walls inter-connected by stay-plates placed between said heat exchanger modules, and top and bottom walls and end walls fitted with reinforcing elements to prevent their deformation due to the pressure of said working fluid.
  • the heat exchanger could be of the same type described in Patent Application PCT/EP2006/067252.
  • the reinforcing elements may be rods applied externally to the walls of the casing.
  • the stay-plates connecting the side walls of the casing may have an area considerably smaller than that of the casing walls, so as not to block the passage of working fluid inside the casing.
  • FIG. 1 shows a perspective view of a boiler according to the invention
  • FIG. 2 shows a plan view of the boiler in FIG. 1 ;
  • FIG. 3 shows a side view of the boiler in FIG. 1 ;
  • FIG. 4 shows a section view along line IV-IV of FIG. 2 ;
  • FIG. 5 shows a section view along line V-V of FIG. 3 ;
  • FIG. 6 shows a simplified side view only of the heat exchanger
  • FIG. 7 shows a front view only of the heat exchanger
  • FIG. 8 shows a section view along line VIII-VIII in FIG. 6 .
  • a boiler 1 according to the present invention is shown in FIGS. 1-5 . It can raise the temperature of water or another working fluid through heat exchange with hot air and fumes, which constitute the exchange fluid.
  • the boiler 1 includes a heat exchanger 50 formed by eight exchanger modules 2 adapted to form a combustion chamber 2 B, slotted exchange walls 2 C and an ejection chamber 2 D.
  • a burner 3 shown diagrammatically in FIGS. 1-5 , is applied to the combustion chamber 2 B at the inlet 51 of the first of the eight heat exchangers 2 , while a discharge flue 4 is connected to the outlet 52 of the ejection chamber 2 D.
  • the exchange fluid, generated inside the combustion chamber 2 B, passes through the exchange walls 2 C and then to the expulsion chamber 2 D and the discharge flue 4 .
  • the modules are built in a substantially parallelepipedal air-tight casing 5 , shown in FIGS. 1-5 .
  • a casing 5 is formed by the following walls:
  • the casing 5 contains the working fluid that exchanges heat with the exchange fluid through the exchange walls 2 C.
  • a working fluid is introduced through a conduit 7 B and is ejected through another conduit 7 C; both conduits 7 B and 7 C are incorporated into the front wall 5 C, which also includes the inlet 51 , the support means for burner 3 and the outlet 52 leading to the discharge flue 4 .
  • Three stay-plates or panels 6 structurally connect the side walls 5 D, and are positioned so as to be parallel to the exchange walls 2 C and the front walls 5 C; such panels 6 have welded ends 10 , so that they can be securely inserted within cavities 11 between the side walls 5 D (in other embodiments, other means of attachment may be used, provided that they are adapted to integrally join the panels 6 to the side walls).
  • cavities 11 appear as slots in the metal sheet that forms the side walls 5 D.
  • the size of panel 6 is such that its height is considerably shorter than the height of the exchange walls 2 C, so as not to block the passage of working fluid.
  • the action of the panels 6 is to reciprocally hold the two side walls 5 D in place, preventing them from deforming, even when the pressure of the exchange fluid increases to 4.5 bar.
  • the reinforcement rods 8 are applied to the front and rear walls 5 C and to the top and bottom walls 5 B, which structurally reinforce the casing 5 , preventing the walls from deforming under high pressures.
