Definitions

  • the invention relates to a boiler for the combustion of liquid or gaseous fuels according to the preamble of the main claim.
  • Such boilers are well known and do not require any special written proof in this respect and in detail. Also known in connection with such boilers are measures and embodiments which are intended to make such boilers condensate-proof, which requirement of such boilers is also more or less well met.
  • the relevant measures in this regard range from enamelling the endangered walls via cast inserts to double and multi-layer design of the walls exposed to heating gases.
  • the idea of using ceramic material, which has been used since the beginning of furnace and boiler construction, for modern boiler construction is also not new and is being increasingly considered again, especially because corrosion risks are not only caused by the Pollutants present in the fuels and becoming active during combustion, the effects of which could largely be countered satisfactorily with the abovementioned measures, but also because of the pollutants increasingly present in the air.
  • the invention is therefore based on the object of improving a boiler of the type mentioned using ceramic material to the effect that it is not only sufficiently resistant to pollutants resulting from the fuels, but also against pollutants from the air, with the proviso that to maintain the proven design and functional principle of boilers of the generic type and to design the ceramic material in such a way that such a boiler can be produced at a reasonable cost.
  • the main problem of the liquid and pressure-tight integration of the ceramic body in the water-carrying sheet steel housing is due to its simple geometric shape in the form of a cylinder simply solved that on the one hand provides for polished sealing seat surfaces on the ceramic body or on the other hand arranges the cylindrical ceramic molded body in a continuous sheet steel tube of the water-carrying housing.
  • the inner cylinder which is preferably rib-free and forms the combustion chamber wall, is manufactured with undersize so that it can be used in the outer cylinder provided with longitudinal ribs.
  • the inner cylinder is then suitably widened by the insertion tolerance measure, so that the inner cylinder comes into contact with the free ends of the longitudinal ribs of the other cylinder.
  • the two ceramic cylinders are advantageously of the same length, the necessary heating gas overflow opening for the transfer of the heating gases into the heating gas trains being formed from a plurality of slots in the inner tube train and each slot leading to at least one of the individual trains delimited by the longitudinal ribs.
  • the edges are advantageously formed by through openings in the front and rear walls of the water-carrying housing in the form of at least one ring groove and this is either formed from the opening edge areas of the walls or molded onto them as an additional part, which is closer is explained.
  • the ceramic tube can be slightly tapered at its insertion end be so that it can better pass through the sealing rings, which automatically get an interference fit between the ring groove and the ceramic body after passage of the conical area.
  • the additional part forming the annular groove is designed as a conical ring collar which can be fastened to the front and rear walls of the housing and encloses a wedge-shaped gusset space with the front and rear walls.
  • the seal and the ring collar are to be dimensioned or designed so that there is a press fit for the seal when the ring collar is attached to the front and rear walls. Since in this embodiment the ceramic tube can first be inserted into the water-bearing housing without seals, an advantageous embodiment with regard to the outer tube is to provide the ground sealing seat surfaces with at least one surface-enlarging profile, into which the sealing ring is then pressed after the ring collar has been tightened.
  • the two ceramic tubes are arranged in a sealing tube made of sheet steel and welded to the water-carrying housing.
  • a sealing tube made of sheet steel and welded to the water-carrying housing.
  • the boiler according to the invention is preferably designed such that the closure carrying the burner and the flue gas collection chamber are arranged on the front and rear walls of the housing without contact with the two ceramic tubes. This is also provided because it would be absolutely problematic to attach these burner and fume cupboard tube closures to the ceramic bodies themselves.
  • the boiler consists in a known manner of a water-carrying housing 16, which is penetrated by a pipe 1 enclosing the combustion chamber 8 and the heating gas-carrying rooms divided into individual sections, which is closed at one end with a closure 23 carrying the burner 25 and at the other End in an exhaust gas collection chamber 24 with exhaust gas connection 24 'opens.
  • the pipe run 1 is formed from liquid-tight ceramic material, which is ground in the area of the passage openings 2 of the front and rear walls 3, 4 of the housing to form sealing seat surfaces 5.
  • At least one sealing ring 7 is placed between the opening edges 6 (see in particular FIGS. 3 - 6) of the front and rear walls 3, 4 of the housing and the ground sealing seat surfaces of the outer tubing 1.
  • a second, smaller diameter, surrounding the combustion chamber 8 is seated in the tube pull 1 and provided on the extractor side with an inserted bottom 9, pipe tube 10, which is also made of ceramic material.
  • the bottom 9 can also consist of ceramic material or of another suitable, refractory material.
  • longitudinal ribs 12 are provided in the annular cylindrical space 11 between the two pipe runs 1 and 10 as parts of the outer pipe run 1, which, as can be seen in FIG. 2, rest with their free ends 13 on the wall of the inner pipe run 10.
  • the two pipe runs are advantageously of the same length, as a result of which the two pipe runs can be mutually supported over their entire length.
  • the heating gas overflow opening 14 is formed from a plurality of slots 14 'on the inner tube train 10, each slot 14' to at least one of the the longitudinal ribs 12 limited individual trains 15 (Fig. 2) leads. Possibly. a slot can be made so wide that a slot detects several individual trains 15 lying next to one another.
  • FIGS. 3 to 6 With regard to the attachment of seals in the form of sealing rings 7, reference is made to FIGS. 3 to 6. As can be seen from these representations, the edges 6 of the through openings 2 of the front and rear walls 3 and 4 of the housing 16 are designed in the form of at least one annular groove 17 (FIGS. 3, 4), these opening regions of the walls 3, 4 molded (Fig. 4, 5) or as an additional part 18 (Fig. 3) is molded onto this. With regard to the requirements to be observed, reference is made to the above explanations in this regard.
  • the ground you tion seat surface 5 is provided with a plurality of surface-enlarging profiles 20, into which the corresponding cross-section-sized sealing ring 19 when tightening the ring collar 18 ', as shown, presses.
  • the embodiment according to FIG. 7 differs from the previously described embodiment only in that this boiler design advantageously does without special seals, as described above.
  • the pipe run 1 is in contact with the pipe run 21 or between the pipe run 1 and the pipe run 21 an elastic, heat-conducting mass layer 22 is arranged.
  • both constructions have in common that the outer ceramic tube 1 sits, so to speak, "floating" in the water-carrying housing 16.
  • water-carrying housing 16 does not necessarily have to consist of sheet steel, but can also be formed, for example, from gray cast iron, aluminum, stainless steel or even from ceramic. Even if the housing 16 is made of ceramic, the "floating" integration of the two pipe runs 1 and 10 is essential since the housing 16, because it is cooled, is subjected to different thermal loads than the two pipe runs 1 and 10.
