Definitions

  • the invention relates to a chimney head structure with the features according to the preamble of claim 1.
  • Ventilation chimneys of this type are therefore provided in the casing or in the area of the thermal insulation layer, which are connected to the atmosphere at the lower and upper ends of the chimney and are used to remove the moisture that has penetrated the thermal insulation upwards (see DE-PS 32 11 536).
  • ventilation chimneys of this type are therefore provided in the casing or in the area of the thermal insulation layer, which are connected to the atmosphere at the lower and upper ends of the chimney and are used to remove the moisture that has penetrated the thermal insulation upwards (see DE-PS 32 11 536).
  • DE-PS 32 11 536 There are various suggestions for the removal of the moisture-absorbing air from the ventilation ducts beyond the chimney head.
  • an expansion joint collar projects through the opening of the cover plate into the inner tube and has openings in its jacket for the passage of the ventilation gas. Due to the suction effect generated by the rising warmer flue gases, the aeration gas located outside the inner tube is introduced into the flue gas stream and discharged upwards.
  • the invention is therefore based on the object of creating a chimney head structure in which the thermal insulation in the head area is wetted even with intermittent firing and unfavorable external influences (low temperatures and Wind) can be avoided.
  • the invention is based on the consideration that wetting of the thermal insulation in the head region can only be avoided by preventing the occurrence of condensate on the underside of the cover plate. For this reason, the invention provides that that part of the underside of the cover plate which can come into contact with the ventilation gas emerging from the thermal insulation or from the ventilation ducts (and possibly also with the flue gas emerging from the inner tube) is covered with a thermal barrier coating.
  • the underside of the thermal insulation layer remains at a temperature which is above the dew point of the ventilation gas and the flue gas due to its heat-insulating property. Therefore, even if there is no flue gas flowing upwards through the inner tube during a break in heating and the suction effect on the ventilation gas to promote it is low, there is no condensation on the underside of the cover plate.
  • the insulation of the underside of the cover plate can be limited to the part that lies within the thermal insulation layer that extends to the underside of the cover plate. In such a case, however, it may also be expedient to isolate the part of the underside of the cover plate that lies outside of it, because this generally keeps the temperature on the underside higher.
  • the thermal insulation layer on the underside of the cover plate preferably consists of mineral or rock wool, which is bound to form plates or shells that are reasonably stable.
  • it can simply be inserted between the upper end of the thermal insulation surrounding the inner pipe and the underside of the cover plate.
  • the connection can either be made by gluing the thermal insulation layer to the underside of the cover plate or by direct molding during the production of the cover plate.
  • the heat insulation layer in plate form can serve as lost formwork during direct molding .
  • the opening of the cover plate in its transverse dimensions e.g. the diameter must be dimensioned so large that the thermal insulation surrounding the inner tube can be pulled up through the opening and is covered there by a plate which projects laterally from the expansion joint collar.
  • the ventilation gas can be discharged upwards through an annular gap remaining between the thermal insulation and the opening edge. It is expedient here to provide an annular projection surrounding the opening on the upper side of the cover plate, the inner wall of which also optionally carries a thermal insulation layer to avoid the formation of condensate.
  • Fig. 1 shows the chimney head of a prefabricated fireplace, which consists essentially of an inner tube 1 guiding the flue gas, a thermal insulation 2 closely surrounding the inner tube of dimensionally stable mineral fiber shells and a casing 3 made of individually placed casing stones.
  • a cantilever plate 4 is supported on the penultimate casing stone 3, on which in turn the uppermost or last casing stone 3 is seated and which also carries a chimney head casing 5.
  • On the casing 5 is a cover plate 6 made of concrete or the like. and is mortared at 7.
  • the cover plate 6 has a circular opening 61, which is, for example, shaped to match the cylindrical inner tube and through which an expansion joint collar 9 extends downward into the inner tube 1.
  • the expansion joint collar 9 has a laterally projecting plate 10 with which it is fastened to the top of the cover plate 6. Below the cover plate, the expansion joint collar 9 has openings 11 through which ventilation ducts 12 pass ventilation gas rising outside the thermal insulation 2 can enter the interior of the expansion joint collar 9.
  • the outer thermal insulation 8 and the last casing stone 3 are drawn up to the underside of the cover plate 6 and in this way limit an inner region of the underside of the cover plate, which is covered with a heat insulation layer 62.
  • a heat insulation layer 63 also covers the inner surface of the opening 61 and extends in the radial direction up to close to the outer surface of the expansion joint sleeve 9. Through the heat insulation layers 62, 63, the temperature of the underside of the cover plate 6 in the above-mentioned inner region, from which the Ventilation channels 12 emerging ventilation gas is coated, be kept so high that condensation does not occur.
  • FIG. 2 shows an embodiment 6a of the cover plate, which essentially corresponds to that according to FIG. 1, but differs from it by the omission of the cylindrical-shell-shaped thermal insulation layer 63 at the inner opening edge.
  • the opening 61 of the cover plate 6a is selected in its dimensions so that it extends close to the circumference of the expansion joint sleeve 9. 2 shows the embedding of the thermal insulation layer 62 provided on the underside of the cover plate 6a, which is also practiced in the embodiment according to FIG. 1.
  • the cover plate 6a has a recess 64 on its underside, the depth of which corresponds largely to the thickness of the thermal insulation layer 62, so that its underside lies essentially in one plane with the remaining part of the underside of the cover plate 6a.
  • Fig. 2 also shows that the underside of the heat insulation layer 62 is covered with a vapor diffusion barrier 65, for example in the form of an aluminum foil.
  • a corresponding vapor diffusion barrier is also provided in the embodiment according to FIG. 1 and also extends into the vertical region in which the cylindrical shell-shaped thermal insulation layer 63 is provided.
  • FIGS. 3 to 5 show different possibilities for forming the cover plate and for guiding or discharging the ventilation gas emerging from the thermal insulation.
  • 3 has such a large diameter that the opening is aligned with the ventilation channels 12 in the inner casing 3.
  • the inner thermal insulation 2 and the inner tube 1 extend through to the top of the cover plate 6b and the opening 61 is covered by a plate 67 standing on individual supports 66, which is integral with an expansion joint sleeve 9.
  • the cover plate 6b also has on its underside in the part which lies within the outer casing 5, a thermal insulation layer 62 which in this case simply rests on the upper end face of the casing 3 and the external thermal insulation 8 surrounding it.
  • the cover plate 6c according to FIG. 4 is supported with its flat underside on the outer casing 5, but has a conically increasing shape of its underside within the casing 5.
  • an annular projection 68 protrudes from its upper side, which surrounds the opening 61 in such a way that the inner surface of the annular projection and that of the opening are flush with one another.
  • a thermal insulation layer 62 is also provided on the underside of the outer casing 5 in the conical region, and a thermal insulation layer 63 covers the inner surface of the opening 61 up to the upper end of the ring projection 68.
  • the plate 67, which covers the opening 61, is supported in this embodiment with individual supports 66 on the upper end face of the ring projection 68.
  • the cover plate 6d according to FIG. 5 corresponds in principle to the cover plate 6c according to FIG. 4, but with the difference that a conical design of the underside is missing.
  • the thermal insulation layer 62 is limited to the common radial thickness of the inner casing 3 and the thermal insulation 8 surrounding it and is inserted between the upper side and the lower side of the cover plate 6d.
  • a thermal insulation layer 63 extends over the inner surfaces of the opening 61 and the ring projection 68, which are aligned with one another.
