Definitions

  • the invention relates to a chimney pipe element with a double-walled, supporting pipe, the outer and inner jacket of which are designed as metal pipes and are connected to one another by means of end caps.
  • chimney pipe elements have been known for a long time. They are used as prefabricated elements for the construction of fireplaces, especially for wood and solid fuel firing.
  • the double-walled structure is intended to serve as thermal insulation so that the outer jacket does not experience excessive temperatures. Even when using thermal insulation materials in the space between the outer and inner pipe, the thermal insulation has proven to be insufficient, especially at high exhaust gas temperatures, such as those that occur with wood firing.
  • the insert tube made of bonded ceramic fibers, preferably aluminum oxide silicate fibers, can thus form a continuous, heat-insulating flue gas tube, while the double-walled tube has a predominantly supporting function.
  • the condensate possibly formed by the thermal insulation and the associated temperature gradients in the insert tube is evaporated by the air circulation in the space mentioned and discharged to the outside. Since the insert tube does not essentially touch the inner jacket, the condensate does not usually get onto the inner tube and otherwise also dries out. With this construction, it can in particular be avoided that parts of the outer tube in the area of the end caps are touched by the flue gas duct, thus preventing thermal bridges.
  • FIG. 1 a chimney pipe element according to the invention is shown in section perpendicular to its axis.
  • a double-walled, supporting tube 1 has a tubular outer jacket 4 and an inner jacket 5, between which a thermal insulation 6, e.g. is arranged from a mat of ceramic fibers or mineral wool.
  • Inner and outer jacket 4,5 are made of stainless steel, the inner jacket e.g. can be made of particularly corrosion-resistant chrome-nickel-molybdenum stainless steel with a wall thickness of 1 mm.
  • the inner and outer shells are connected to one another via upper and lower metal end caps 9, 10 (FIG. 2) and thus form a load-bearing, rigid element.
  • the individual elements are inserted with their end caps, as shown in Fig. 2.
  • the profile of the end caps 9, 10 can be designed in a known manner in different ways. Their mounting, centering and sealing functions are essential.
  • a fireproof, corrosion-insensitive insert tube 2 made of bonded ceramic (aluminum oxide silicate) fibers is arranged within this supporting tube.
  • An intermediate space 3 is formed by means of webs 7 between this insert tube 2 and the supporting tube 1.
  • the webs 7 determine the distance between the inner jacket 5 of the supporting tube 1 and the insert tube 2 and di Enen to hold the same in the supporting tube 1.
  • the webs 7 are connected to the inner jacket 5 by gluing. Because the bonded ceramic fibers, which form the insert tube 2, have a relatively low, mechanical stability, they are not designed as load-bearing parts.
  • the insert pipes 2 of adjacent chimney pipe elements adjoin one another in the region of the end caps and form a flue gas duct 8 which does not touch the supporting pipe 1.
  • the space 3 between the outside of the insert tube 2 and the supporting tube 1 extends over the entire length of the element and adjoins the corresponding space of the neighboring element. Air circulation can thus take place through the chimney along the outside of the insert tube 2 or along the inner jacket 5 of the supporting tube. If only three narrow webs 7 are provided, as shown in FIG. 1, the circulation in the longitudinal direction of the chimney is retained irrespective of a twisted mounting of adjacent elements, as is indicated by dashed lines in FIG. 1. The webs 7 'of the neighboring element do not interfere.
  • markings 12 are provided for the position of the webs in the region of the end caps (FIG. 3), which permit correct positioning during assembly.
  • FIG. 4 Such an insert tube configuration is shown in FIG. 4.
  • a large number of webs 7 is distributed over the circumference of the insert tube 2. Since the bonded fiber ceramic material does not have great inherent stability, this can be improved by the larger number of webs or ribs 7.
  • a lower chimney Pipe element air passages 11 can be provided through the supporting tube 1 in the intermediate space 3.
  • the insert pipe 2 serves, as mentioned, to guide the flue gas, as indicated by arrows 14 in FIG. 2.
  • the ceramic fibers which are formed in a manner known per se by vacuum forming from a mixture of short-cut alumina silicate fibers with a binder (e.g. cement) to form insert tube 2, form a fire-resistant, heat-insulating, but not completely vapor-tight chimney.
  • the vapor diffusion in connection with the temperature gradient in the insert tube can lead to condensation of moisture. Thanks to the space 3 between the insert tube 2 and the inner jacket of the supporting tube, this condensate essentially does not reach this inner jacket.
  • the air circulation in this space 3 also prevents the condensate from accumulating for a long time.
  • the temperature on the inner jacket 5 of the supporting tube 1 is significantly reduced in operation by the thermal insulation of the insert tube 2 and the intermediate space 3, so that, despite the thermal bridges at the end caps 9, 10, the outer jacket 4 assumes a temperature which is below the permissible maximum values.
  • the webs 7 can be designed in different ways. In the variant shown in the figures, the minimum number of three webs 7 is provided, which extend over the entire length of the element and thus delimit longitudinal channels.
  • the webs are not continuous over the entire element, but rather are interrupted in the longitudinal direction. In particular, they can also be provided only in the area of the end caps.
  • the webs 7 are preferably molded in with the vacuum forming of the insert tubes. However, it is also possible to use them to be retrofitted to the outside on a cylindrically shaped fiber ceramic insert tube.
