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 are used in different, but in principle identical construction forms.
  • this well-known boiler design applies to both steel 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 FR-A-22 37 141) which, nippled on the water side in the area of relatively small overflow openings, are joined to form a block consisting of a large number of individual members.
  • considerable technical effort has to be made, especially in view of the fact that the individual parts or the cast members have to be produced in core casting.
  • binders for binding the molding sand of the cores which are necessary for the formation of the cavities in a core member, are highly toxic.
  • the core molding sand which can no longer be used after casting, can therefore generally not simply be deposited in normal landfills and must be brought to special landfills, which is associated with high costs and considerable circumstances.
  • the formation of cast kettles from a large number of individual members which are closed except for the small openings to be nippled means that the amount of casting material required is relatively high, ie cast kettles of this type inevitably have a considerable weight.
  • the invention is therefore based on the object of improving and creating a boiler of the type mentioned which, with regard to its essential parts forming the combustion chamber, is to be made of material which is favorable in terms of condensate resistance, but these parts, insofar as they are made of cast iron, can be cast without cores and should thus be able to be produced economically and in a manner that is gentle on the environment, 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, also for the parts delimiting the combustion chamber To be able to consider ceramic material.
  • the new type of boiler is made up of geometrically very simple parts that can be sealed easily and without nippling joined together form the combustion chamber, while the casing which closes the water-conducting housing to the outside is simply formed from sheet steel.
  • the core-free formability of the elements due to their simple geometrical design not only eliminates the entire core casting and disposal effort for the molding sand, but also allows a much larger width dimensioning of the individual links compared to the width dimensioning of cast members customary today .
  • the coreless casting of the links according to the invention also allows problem-free and advantageous special and further shaping of the links, particularly in the direction of a sufficiently pressure-resistant design, as thin-walled design of the walls as possible 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 design of the boiler according to the invention with regard to the links also has the great advantage that, despite the link design, there is a water-carrying interior which is not divided by narrow and small overflow openings, but rather an interior which is practically that of a "normal" steel boiler corresponds.
  • 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 also created for being able to form these rings from ceramic material.
  • the geometrically simple shape of the rings is achieved in particular in that, in the case of a boiler of this type, the outer wall of the water-carrying interior space consists of a sheet steel jacket which is simple to produce.
  • Fig.l shows a longitudinal section through the boiler
  • FIGS. 1 and 2 show a detailed section according to circle A in FIGS. 1 and 2
  • the boiler consists of a water-bearing housing 3, provided with flow and return connections 1, 2, which is penetrated by a fire chamber, the openings 5 of which are provided at both ends with closures 6, 7, of which one 6 is used ⁇ opening 8 for the burner 9 and the other contains the exhaust gas duct.
  • the water-carrying 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 off the water-carrying interior 13 from the outside.
  • the sheet steel jacket 12 and the rings 11 are arranged between the end members 10 clamped by means of the tension 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 tensioning 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 tongues and tongues 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 requires no further explanation. As can be easily seen and imagined. in any case, the manufacture of the casting mold for the rings 11 and the two end members does not require the use of mold cores, since these elements have no cavities.
  • the burner-side end member 10 is provided with a connecting ring collar 19, which ring collar 19, as can be seen, is also slightly conical in cross section.
  • the other trigger-side end member 10, which has the trigger connector 20, is essentially designed as a slightly curved disc, as shown.
  • 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 projecting beyond the steel sheet jacket 12, on which the tensioning rods 14 'can then be attached.
  • connection extensions 22 which then serve as abutments for the outer tie rods 14 '.
  • the connection of the forward and backward 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 broken lines.
  • the rings 11 have a very simple geometric shape and since there is also a very simple principle of assembling the rings by clamping between the two end members 10, this also opens up the possibility of forming these rings 11 from ceramic material, yes is known to have significantly more favorable properties than condensate strength than Cast iron.

Abstract

La chaudière est destinée à brûler des combustibles liquides ou gazeux et se compose d'un corps (3) pour la circulation de l'eau comportant des raccords d'alimentation et de retour (1, 2) et entièrement occupé par un foyer (4) dont les ouvertures (5) à ses deux extrémités sont équipées de dispositifs d'obturation (6, 7) dont l'un (6) contient l'orifice (8) pour l'adaptation du brûleur (9) et l'autre (7) la conduite des gaz brûlés. Dans l'invention, cette chaudière est constituée de telle manière que le corps de circulation de l'eau (3) soit formé de deux pièces d'extrémité (10), ainsi que d'au moins deux pièces circulaires (11) formant la paroi (4') du foyer et d'un revêtement en tôle d'acier (12) fermant vers l'extérieur l'espace intérieur de circulation de l'eau. Le revêtement en tôle d'acier (12) et les pièces circulaires (11) sont tendus entre les pièces d'extrémité (10) au moyen de tirants (14) traversant l'espace intérieur (13), fixés par un dispositif étanche aux pièces d'extrémité (10) et répartis régulièrement sur le pourtour, et tous les points où s'exerce une poussée, situés entre le revêtement en tôle d'acier (12) et les pièces d'extrémité (10), entre les pièces d'extrémité (10) et les pièces circulaires (11) et entre les différentes pièces circulaires (11), sont équipés de dispositifs d'étanchéité (15).
