Definitions

  • the present invention relates to a boiler improved cast iron element type comprising at least one intermediate element reinforced heat exchanger with surfaces additional exchange.
  • each intermediate element reinforced exchanger passes through the combustion chamber.
  • the invention also relates to such an intermediate element reinforced heat exchanger for boilers in medium and high power cast iron in the area of domestic, collective heating and semi-industrial.
  • the boilers covered by the invention are made up of a horizontal succession of elements exchangers assembled together by juxtaposition horizontal using tie rods and nipples.
  • This invention does not provide any structure of exchange leading the water and crossing the room combustion.
  • the length of the combustion chamber such boilers increases rapidly from a certain power. This augmentation is so fast that the combustion chamber quickly becomes noticeably longer than the flame or exceeds the standard lengths.
  • Figure 2 shows the principle of constitution of the improved boiler according to the invention.
  • Said boiler is conventionally formed a front facade element 1 on which is mounted a burner 2, for example with supply air, of a rear panel element 3 and heat exchanger elements simple intermediates such as 4 or reinforced 5, the assembly being assembled by nipples and horizontal tie rods.
  • the exchanger elements 4 and 5 have at upper part of flues such as 6, with spikes or with fins, arranged symmetrically in several horizontal floors.
  • first group 7 along which combustion gases and fumes are evacuated towards the front of the boiler, along a route horizontal go A, by a compartment of return 8 from the back cover, then evacuated to the rear, along a horizontal return path B, the along a second group 9 of several floors of flues by a collector 10 of front facade.
  • the exchanger elements 4 and 5 have in their second half a passage from flame, respectively 11 and 12, completely free for the first or occupied by items additional exchange which will be discussed below for the latter.
  • the burner projects a developing flame 13 along a combustion chamber 14. formed by the succession of flame passages 11 and 12 of the different intermediate exchangers simple then reinforced delimiting a first part 15 then a second part 16.
  • the original feature of this boiler is located at the level of the intermediate elements reinforced 5 of which one is shown in detail on the figure 1.
  • These reinforced intermediate elements are made up so that after assembly, the second part 16 of the combustion chamber 14 is fitted with exchange surfaces additional, formed by the presence of a group of additional water channels crossing the passage of flame and communicating with the envelope 17 of water circulation surrounding said combustion chamber.
  • the chamber combustion 14 consists of the first classic part 15 in 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 smoke return to the front of the boiler along the flues A and are directed to the outlet of gases and fumes from combustion in the upper part of the rear panel 3 by the upper flues B arranged on several horizontal floors.
