Definitions

  • the invention relates to a chimney extension adapted to be installed on a chimney body, in particular to the outlet of a diameter-standardized flue lining, provided for this purpose with a bottom part with an internal groove for round seal, with a connecting reduced part with a transition to the upper part with a dispersion cone for lateral dispersal of the outlet flue gas.
  • chimney extensions used in tubular form, that increase the natural draft of the chimney.
  • these chimney extensions have a cover fixed to the upper end, for example in the form of a small roof or a rotating head, which, in addition to prevention of rainwater drainage, is rotated by the influence of the flowing air so that the flue gas flows so-called "windward", thereby partially increasing the draft of the chimney.
  • the disadvantage of all these known embodiments of chimney extensions is that they increase or, on the contrary, dangerously reduce the draft of the chimney with relatively low impact on the emissions and fuel economy.
  • DE 20 2008 006043 U1 discloses a chimney extension adapted to be installed on a chimney body with a bottom part with an internal groove for round seal and a connecting reduced part with a transition to the upper part with a dispersion cone for lateral dispersal of the outlet flue gas to the ambient environment through side perimeter carve-outs under the cover lid.
  • DE 20 2008 006043 U1 provides the basis for the two-part form of claim 1.
  • the chimney extension of FR 2 438 795 comprises a dispersion cone with holes. But the openings merely serve to hold the noise absorbing material within the lid. They have no flow directing function.
  • the object of the present invention is to provide a chimney extension with stabilizing effects on exhaust of the flue gas, regardless of the variability of the outdoor environment, according to claim 1.
  • the chimney extension is preferably adapted according to the present invention so that the side perimeter carve-outs under the cover lid, together with the cut-outs in the upperpart of the dispersion cone, are mutually arranged in one common horizontal plane.
  • the side perimeter carve-outs under the cover lid, together with the cut-outs in the upper part of the dispersion cone are arranged at least to face four sides.
  • Chimney extension 1 adapted to be installed on a chimney body, in particular to the outlet 2 of a diameter-standardized flue lining 3 , provided for this purpose with a bottom part 4, for example with an internal groove 5 for a not displayed round seal ( Fig. 2 ), with a connecting reduced part 6 for connection of various diameters with a transition to the upper part 7 with a dispersion cone 8 for lateral dispersal of the outlet flue gas to the ambient environment through side peripheral carve-outs 9 under the cover lid 10 of the chimney extension 1 .
  • the upper part of the dispersion cone 8 is provided with similar projected cut-outs 11 .
  • the side peripheral carve-outs 9 under the cover lid 10 together with the cut-outs 11 in the upper part of the dispersion cone 8 , are arranged at least to face four sides and are essentially mutually arranged in one common horizontal plane.
  • the diameter of the reduced part 6 together with the bottom part 4 are naturally adapted, while the size of the upper part 7 may remain essentially the same, while its adaptation for connection to the reduced part 6 consists of cutting or shortening its tampered part 13 along the indicated line ( Fig. 2 ), thus changing its diameter in the specific area.
  • the narrowed profile of the reduced part 6 contributes to the increased outflow speed of the flue gas before its impact on the dispersion cone 8 and thus their faster dispersal to the ambient environment through the side peripheral carve-outs 9 in the upper part 7 .
  • the reduced part 6 may contain an inner drip lip 12 which also serves as a stop with respect to the outlet of the flue lining 3 .
  • main thrust component X may try to thrust inside the chimney extension 1 by ingress through any but always only one peripheral carve-out 9, but thanks to the opposite arranged cut-outs 11 in the dispersion cone 8 it may pass under the lid 10 all the way to the other side of the chimney extension 1, without significantly affecting the flue gas outlet on that side and not causing dangerous and otherwise adverse blasting of these flue gases back to the chimney at all.
  • Other thrust components XY are essentially passing the chimney extension 1 without further adverse effects and impacts on chimney draft etc.
