Definitions

  • the present invention relates to an improved boiler.
  • the invention concerns a boiler comprising a cap - manifold assembly for permitting limiting the use of high temperature insulating elements and gaskets, thus permitting remarkable savings.
  • boilers used for heating or for sanitaria water production are provided with heat exchangers.
  • a further technical problem solved by the present invention is that of insulating the internal parts of the heat exchanger, particularly in view of the fact that the temperature close to the burner is generally very high, thus reducing the use of expensive refractory material insulating elements.
  • Object of the present invention is therefore that of suggesting a heat exchanger with a cap - manifold assembly, permitting thermally insulating burner and combustion chamber, thus avoiding the use of refractory insulating materials, and reducing the final costs.
  • an improved heat exchanger comprising a water inlet duct and a water outlet duct, between which a heat exchanger is provided, comprised of a spiral duct through which water to be heated passes; said heat exchanger defining a combustion chamber within which a burner is provided, said burner being supplied by an air-gas mixture; and upper cap placed so as to be in touch with at least the last upper turn of the heat exchanger duct, and a lower cap, placed distanced from the last lower turn of the heat exchanger duct, so as to create a gap for passage of gas and discharging condensate; said heat exchanger being characterised in that it comprises a manifold element having such a surface to innerly occupy the upper surface of said combustion chamber having, a concave shape and placed above said upper cap, with the upper surface of which it realises a cavity within which an air - gas mixture is collected before being conveyed within said burner.
  • said upper cap can have a substantially flat upper surface.
  • said manifold element can be comprised of metal, preferably aluminium, or of plastic material.
  • said cap can be coupled with said manifold element.
  • coupling each other of said cap and said manifold element can be adjusted by rotation.
  • said heat exchanger has a metallic disk, shaped to be inserted by screwing within the space of a heat exchanger duct turn, above said heat exchanger being provided an insulating refractory element, with temperature of about 2000°C.
  • said disk can be comprised of steel.
  • duct of said heat exchanger can comprise an annular slot on each end, permitting the coupling with said inlet and outlet ducts without any welding.
  • said heat exchanger can comprise a cylindrical element between said upper cap and said lower cap.
  • said heat exchanger can comprise a plurality of tie rods, each provided with means for fixing at their ends with said upper cap and with said lower cap.
  • said upper cap with gas manifold and said lower cap with discharge collector can be respectively realised integrally each other, or separated.
  • Said heat exchanger 1 provides a combustion chamber 2, within which spiral shaped duct 3' for water to be heated within the heat exchanger 3 is introduced.
  • Said heat exchanger 3 confers a substantially cylindrical shape to the combustion chamber.
  • Heat exchanger 3 has a water inlet duct and a water outlet duct, respectively indicated by reference number 4' and 4".
  • Burner 5 is provided substantially along the vertical axis of said combustion chamber 2, close to said burner 5 being provided the ignition spark plug 6 for ignition of the same burner 5.
  • a heat exchanger 3 cap - manifold 7 assembly is provided above said burner 5.
  • Heat exchanger 1 also provided on its base a lower cap 8, while a containment wall is provided laterally.
  • Said cap - manifold assembly and said lower cap 8, coupled by adjustable tie rods 10 acting on their edged, are provided, respectively, at the base of said cylindrical element 9.
  • This assembling mode is particularly efficient and cheap, also permitting maintaining the heat exchanger duct 3' spiral compressed.
  • Cap - manifold 7 assembly is comprised of two parts: cap 7' and manifold element 7".
  • Cap 7' is comprised of metal, preferably aluminium, or any other heat conducting material. It has a substantially flat surface and it is in contact with the last turn of heat exchanger 3 duct 3'.
  • Manifold element 7" is preferably comprised of aluminium or plastic material. It is provided above said cap 7' and has such a dimension to cover the whole cap 7' surface.
  • Said collector 7" has a concave shape and is coupled with said cap 7', realising, along with the same, a cavity 11.
  • Said cavity permits a first thermal insulation from heat irradiated from cap 7' and burner 5. then, air - gas mixture enters within said cavity 11 for supplying burner 5. said mixture has a temperature much lower than the temperature inside the combustion chamber.
  • this arrangement permits use of standard sealing gaskets, preventing the need of using refractory materials.
  • Both cap 7' and lower cap 8 are shaped so as to have an outlet structure for the spiral end from housing comprised of the two caps and the cylindrical element 9. It must be taken into consideration that in the art usually the ends of heat exchanger 3 duct 3' exit through the cylindrical element 9, thus creating problems for sealing and weldings.
  • FIG 3 shows heat exchanger 3 that in the embodiment shown is a spiral exchanger.
  • Heat exchanger 3 duct 3' has annular slots 12 (see figure 4 ) on its ends, permitting the coupling without the need of weldings, only by a joint with gaskets (not shown in the figures).
  • Lower cap 8 is preferably comprised of plastics, aluminium or other metal.
  • Heat exchanger 1 has under said cap 8 a discharge manifold 13 that can be comprised of plastics, aluminium or other metal.
  • figure 5 shows a section of lower closure of combustion chamber 3, wherein a steel disk 14 is placed, having such a shape to be inserted between gaps of a heat exchanger 3 tube turn, above which a heat insulating refractory 15 is provided.
  • a further advantage of the present invention is the fact of permitting an easy, convenient and modular assembling.
