Definitions

  • the present invention relates to an improved cast iron boiler of the element type comprising at least one reinforced heat exchanger intermediate element having additional exchange surfaces.
  • each reinforced intermediate exchanger element pass through the combustion chamber.
  • the invention also relates to such an intermediate reinforced heat exchanger element for medium and high power cast iron boilers in the field of domestic, collective and semi-industrial heating.
  • the boilers covered by the invention consist of a horizontal succession of exchanger elements assembled together by horizontal juxtaposition using tie rods and nipples.
  • exchanger elements conventionally comprise vertical flues which connect the hearth to upper collecting channels.
  • the only particularity of this boiler concerns the presence of substantially vertical guide ribs arranged on or shaped in the heat exchange surfaces as well as horizontal baffles provided thereon at different heights.
  • This invention does not provide any exchange structure conducting water and passing through the combustion chamber.
  • the length of the combustion chamber of such boilers increases rapidly from a certain power. This increase is so rapid that the combustion chamber quickly becomes significantly longer than the flame or exceeds the standard lengths.
  • FIG. 2 shows the principle of constitution of the improved boiler according to the invention.
  • Said boiler is conventionally formed of a front facade element 1 on which is mounted a burner 2, for example with blown air, of a rear facade element 3 and of simple intermediate exchanger elements such as 4 or reinforced 5 , the assembly being assembled by nipples and horizontal tie rods.
  • the exchanger elements 4 and 5 have upper flues such as 6, with pins or fins, arranged symmetrically in several horizontal stages.
  • first group 7 along which the combustion gases and fumes are evacuated towards the front of the boiler, along a horizontal path going A, by a return compartment 8 of the rear facade, then evacuated towards the rear, along a horizontal return path B, along a second group 9 of several stages of flues by a collector 10 of the front facade.
  • the exchanger elements 4 and 5 have in their second half-part a flame passage, respectively 11 and 12, entirely free for the first or occupied by additional exchange elements which will be discussed below for the second.
  • the burner projects a flame 13 which develops along a combustion chamber 14. formed by the succession of flame passages 11 and 12 of the various simple and then reinforced intermediate exchangers delimiting a first part 15 and then a second part 16.
  • the original characteristic of this boiler is located at the level of the reinforced intermediate elements 5, one of which is shown in detail in FIG. 1.
  • These reinforced intermediate elements are constituted so that after assembly, the second part 16 of the chamber combustion 14 is equipped with additional exchange surfaces, formed by the presence of a group of additional water channels crossing the flame passage and communicating with the casing 17 of water circulation surrounding said combustion chamber.
  • the external surfaces of the walls of the water arms 18 and 19 are conventionally provided with pins or fins 20 promoting heat exchange.
  • the combustion chamber 14 After assembly of the boiler, the combustion chamber 14 consists of the first conventional part 15 in a fully open space and the second part 16 partially closed transversely by the succession of water arms 18 and 19 of the reinforced exchangers 5 juxtaposed.
  • the hot gases and fumes return towards the front of the boiler along the flues A and are directed towards the outlet of the combustion gases and fumes in the upper part of the rear facade 3 by the upper flues B arranged on several horizontal stages.
