Definitions

  • the invention relates to a sectional boiler with two end members and at least one middle member, in which a burner chamber provided with a burner tube is arranged in a space formed between the end members and below the middle member (s).
  • the aim of the invention is to propose a boiler of the type mentioned in the introduction, in which an adaptation to the respective conditions is possible in a simple manner, in particular with regard to the expansion of performance. NO x reduction should also be aimed for.
  • the focal surface of a chamber delimited by wall parts and the outflow cross-section of the burner rod or burner rods arranged in this chamber of the relationship are sufficient, where F B is the combustion chamber area, which results from the product of the depth and width of the respective chamber, and F A is the mixture outlet cross section of the burner rod or the burner rods.
  • heat conducting rods are arranged in the vicinity of each burner tube and run parallel to the respective burner tube.
  • the boiler according to the invention has a base plate 25 on which the side walls formed by end members 5 de get up, the end members 5 are flowed through by the heating medium.
  • the end members 5 are essentially L-shaped in cross section, so that they also form part of the ceiling 26 of the burner chamber.
  • the burner chamber is divided several times.
  • essentially T-shaped middle members 6 are provided in cross section, through which the heating medium 9 also flows.
  • the substantially horizontal legs of the end members 5 and the middle members 6 are dimensioned such that their vertical legs are spaced apart from one another, which allows the inclusion of a burner tube 1 in the chamber 3 delimited by the wall parts of the end members 5 and the middle members 6 .
  • intermediate pieces 11 are also provided, which can be inserted between the horizontal legs of the middle links 6 or the end links 5.
  • an enlarged chamber 3 ' is formed, in which two burner tubes 1 running parallel to one another are arranged.
  • the arrangement of the two burner tubes 1 in the chambers 3, 3 ' is such that the ratio of the distance 1 of a burner tube 1 from the next wall part 5, 6 to half the clear distance l max of the two an enlarged chamber 3' delimiting wall parts is.
  • the burner tubes 1 are supplied with a gas-air mixture via a mixture tube 15, the mixing of these two components taking place in the mixture tube 15.
  • a gas nozzle 16 is arranged just before the inlet end of the mixture pipe 15, air being sucked into the mixture pipe 15 when the gas flows into the mixture pipe 15.
  • the wall parts 6 - as shown in FIG. 3 - can have a recess 14 in which the ignition takes place (unhindered jumping of the flame in front of one rod onto the other).
  • an output of, for example, 11 kW can be achieved with two burner tubes and an output of 17 kW with three burner tubes, etc.
  • FIG. 2 also clearly shows that a maximum of two burner tubes 1 are arranged between two wall parts 5, 6.
