Definitions

  • the invention relates to a central heating boiler made of sheet steel with a flame deflection pot in the rear area of a lying, cylindrical combustion chamber.
  • Boilers of this type can be found, for example, in DE-GM 75 24 798.
  • a secondary heating surface is arranged in the form of internals, which are connected in a heat-conducting manner to the wall of the combustion chamber.
  • the internals can have the shape of the ribbed ribbons shown there. Longitudinal ribs of various cross-sections are often also inserted and welded to the wall of the combustion chamber before the flame deflection pot is inserted. The flame deflector is then only loosely inserted.
  • Boilers of this type have the disadvantage that a great deal of welding has to be carried out on the cylindrical wall of the combustion chamber, since only the heat-conducting connection leads to a sufficient one Heat transfer.
  • the combustion chamber is to be provided with a corrosion-resistant coating.
  • the ribs and the many weld seams stand in the way of a perfect coating, so that corrosion resistance cannot always be guaranteed.
  • the aim is to create a boiler that is easy to manufacture and whose heat exchange surfaces can be coated easily and safely. Installations with a heat storage effect that lead to heat losses if the boiler water temperature drops should be avoided.
  • this is done in that a heating gas flue without internals is formed between the flame deflection pot and the wall of the combustion chamber and that in the axial Continuation of the combustion chamber, a secondary heating surface is arranged.
  • the wall of the combustion chamber consists of a cylindrical jacket that is easy to manufacture and can be coated safely. There are no fittings or attachments that hinder a perfect coating and that could lead to heat loss.
  • the secondary connecting cable which preferably consists of pocket-shaped channels with side embossments, can also be easily manufactured and coated. It can be attached to the combustion chamber with little effort. Since the additional cable does not have any heat-storing inserts, the heat losses to the chimney are reduced. Even the heat that was absorbed by the uncooled flame deflector is transferred to the boiler water in the downstream switching cable. This heat was almost completely lost to the chimney in previous boilers.
  • a boiler of this type is suitable, among other things. for smooth control of the boiler water temperature depending on the heat requirement. In doing so, deliberately falling below the dew point with the formation of condensation is accepted. The corrosion to be feared can then be prevented if the endangered areas are protected by special treatment and if it is ensured that the condensate formed at the start of the burner run evaporates again after the dew point has been exceeded in the end phase of the burner run.
  • the flow of the condensate against the boiler door is prevented by a transverse embossing of the front, lower area of the wall of the combustion chamber.
  • the boiler has a combustion chamber 2 formed by a cylindrical wall 1, which is closed at the front by a front door 3 with a burner opening 4.
  • a loose flame deflection pot 5 is inserted and supported by spacer 6 so that an annular cylindrical train 7 is formed.
  • the train 7 merges into a downstream switching train 8 arranged axially behind the combustion chamber 2, which opens into an exhaust pipe 9.
  • the additional cable 8 consists of pocket-shaped channels 10 with side impressions. Such parts can be coated well corrosion-resistant, and they have a very high effectiveness due to the frond flow.
  • embossing 11 In the front, lower area of the wall 1 of the combustion chamber 2 there is an embossing 11 as a condensate accumulation. This embossing 11 prevents the flow of condensate, which can form at a boiler water temperature which is deliberately set below the dew point of the heating gases, against the front door 3. Damages in the sealing area of the door are thereby eliminated.
