Definitions

  • the invention relates to a boiler for burning liquid or gaseous fuels according to the preamble of the main claim.
  • Boilers of the type mentioned are generally known and in use in different but in principle the same construction forms.
  • this well-known boiler design applies both to steel sheet and cast iron boilers, the cast iron boilers consisting of relatively narrow, one-piece and core-cast individual members (see DE-A-20 17 992 and DE-A-37 18 115) the block, which exists in the area of a relatively large number of individual members, is joined together.
  • the cast iron boilers of this type accessible for a reasonably rational series production, considerable technical effort must be made, especially considering that the individual parts or The binders for binding the molding sand of the cores, which are necessary for the formation of the cavities in a boiler member, are partially highly toxic.
  • the core molding sand which can no longer be used after the casting, can therefore generally not be used without further deposited in normal landfills and must verb on special landfills be costed, which is associated with high costs and considerable circumstances. Due to the formation of cast kettles from a large number of individual members which are closed except for the small openings to be nippled, the amount of casting material is also relatively large, ie cast kettles of this type inevitably have a considerable weight.
  • the invention is therefore based on the object to improve and create a boiler of the type mentioned, which should be made with respect to its essential parts forming the combustion chamber from material favorable in terms of condensate resistance, but these parts, insofar as they are made of cast iron are core-free castable and thus should be production-efficient and environmentally friendly to manufacture, and with the additional requirements of assembling such a boiler from only a few parts with little assembly effort and, on the basis of the training principle for the parts delimiting the combustion chamber, also being able to consider ceramic material.
  • the new type of boiler is made up of geometrically very simple parts that can be sealed in a simple manner and without nippling Form the combustion chamber, while the casing that closes off the water-carrying housing is simply formed from sheet steel.
  • the core-free formability of the elements due to their simple geometric design not only eliminates the entire core casting and disposal effort for the molding sand, but it also allows a much larger width dimension of the individual links compared to the current width dimension of cast members.
  • the coreless casting of the links according to the invention also allows problem-free and advantageous special and further shaping of the links, in particular in the direction of a sufficiently pressure-resistant design, the thin-walled design of the walls and a simple and basically identical design of the end links aim what is explained in more detail and what is covered in part of the subclaims.
  • the inventive design of the boiler with respect to the links also has the great advantage that, despite the link construction, there is a water-carrying interior that is not divided by narrow and small overflow openings, but an interior that practically corresponds to that of a "normal" steel boiler.
  • With regard to the "green formability" it is essential that vertically oriented surfaces in the casting mold must have a corresponding conicity in order to be able to draw the positive model when producing the casting mold from sand. Due to the geometrically simple shape of the rings, however, the prerequisite is created to be able to form these rings from ceramic material.
  • the geometrically simple shape of the rings is achieved in particular in that the outer wall of the water-carrying interior consists of a steel sheet jacket which is easy to manufacture in such a boiler.
  • the boiler consists of a water-bearing housing 3, provided with supply and return connections 1, 2, which is penetrated by a combustion chamber, the two openings 5 of which are provided with closures 6, 7, one of which 6 is the insert opening 8 for the burner 9 and the other contains the exhaust system.
  • the water-bearing housing 3 is formed from two end members 10, further from at least two rings 11 forming the combustion chamber wall 4 and from a steel sheet jacket 12 which closes the water-bearing interior 13 to the outside.
  • the sheet steel jacket 12 and the rings 11 are clamped between the end members 10 by means of the tensioning rods 14 which pass through the interior 13 and are sealed to the end members 10 and are evenly distributed over the circumference.
  • the type of sealing and fastening of the tie rods 14 can be seen better from the enlarged detailed illustration in FIG. 3.
  • all joints between the steel sheet jacket 12 and the end members 10, between the end members 10 and the rings 11 and between the rings 11 themselves are provided with sealing devices 15. This is also shown more clearly in FIG.
  • the sealing devices 15 are designed in the form of tongue and groove and sealing rings 17 are arranged in the grooves 16.
  • the rings 11 and the two end members 10 are cast parts, the rings 11 being provided with longitudinal ribs 18 on the combustion chamber side. What is important for these castings is their weakly conical shape, specifically in the areas for which the problem-free drawing of the positive mold model from the molding sand must be ensured, which does not require any further explanation. As can easily be seen and imagined, the manufacture of the casting mold for the rings 11 as well as the two end links does not require the use of mold cores, since these elements have no cavities.
  • the burner end member 10 is provided with a connecting collar 19, which collar 19, as can be seen, is also weakly conical in cross section.
  • the other trigger-side end member 10, which has the trigger connection piece 20, is essentially designed as a slightly curved disc, as shown.
  • only the connecting piece 20 is weakly conical with respect to its wall. If casting inaccuracies require this, the elements involved in joints are machined in these areas.
  • connection extensions 22 (see FIG. 2) with ease, which then serve as abutments for the outer tie rods 14 '.
  • connection of the supply and return connections 1, 2 to the steel sheet jacket 12 is the simplest, they are preferably attached to the steel sheet jacket 12, as also shown in dashed lines.
  • the rings 11 have a very simple geometric shape and since there is also a very simple principle of assembling the rings by bracing between the two earth members 10, this also opens up the possibility of forming these rings 11 from ceramic material, which, as is well known, is still essential in terms of condensate resistance has more favorable properties than Cast iron.
