Definitions

  • the invention relates to a chimney cap with at least one pipe socket delimiting the flue gas passage opening and with a casing arranged coaxially with the latter, projecting above and surrounding it, open at the top and bottom.
  • Chimney caps of the above-mentioned type have the disadvantage that the part of the pipe socket located above the front of the chimney head, which is above the chimney head and thus outside the chimney, due to the flow of cold air, which may be mixed with water or snow, below the condensation temperature of the flue gas components which are harmful to the chimney is cooled and the chimney is destroyed over time under the influence of the condensates flowing into it.
  • the object of the present invention is to provide a chimney cap in which this part of the pipe socket, which is critical with regard to condensate formation, is sufficiently insulated over the entire service life of the chimney cap, in order to ensure condensate formation inside the pipe socket, with the correct setting and design of the other parts of the furnace, under all weather conditions avoid.
  • the above-mentioned object is achieved according to the invention in that the pipe socket on its part protruding from the chimney to form an air insulation gap surrounding it is surrounded by a tubular shielding part arranged coaxially to it, which is avoided while avoiding it a cold bridge formation between the shielding part and the pipe socket at its upper end via heat-insulating fasteners connected to the pipe socket and thereby fixed in position with respect to the pipe socket and is provided at its lower end with beads to support it on a chimney.
  • the shielding part extends to form a slight air circulation between the air insulation gap and the outside atmosphere up to just above a support flange connected to the pipe socket, preferably via thermal insulation.
  • the air insulation gap is closed at its upper and / or lower end by avoiding the formation of cold bridges by means of the heat-insulating fastening means.
  • the heat-insulating fastener expediently consists of silicone rubber.
  • the shielding part is widened outwards, preferably flanged, at least at its lower end.
  • the upper, at least partially open end of the air insulation gap is surmounted by the upper, preferably flanged end of the pipe socket and / or shielding part to prevent water or snow from entering.
  • the support flange is designed as a chimney cover element or is part of one or, preferably via thermal insulation, is connected to such.
  • the casing has at least approximately the shape of the lateral surface of a preferably eight-sided regular prism or a truncated pyramid.
  • the chimney cap has an inner jacket which is arranged coaxially with the jacket, surrounded by the latter and surmounted by it, preferably at least approximately truncated pyramid-shaped.
  • the chimney attachment shown is provided with a pipe socket 1 which delimits the flue gas passage opening, for example made of copper, a casing 2 which is arranged coaxially with the latter and which projects above and surrounds it and which is open at the bottom and top, and with a pipe socket 1 Provided via a heat insulation 7, made of copper support flange 3, so that the pipe socket 1 is designed in this way as an expansion joint sleeve.
  • a pipe socket 1 which delimits the flue gas passage opening, for example made of copper
  • a casing 2 which is arranged coaxially with the latter and which projects above and surrounds it and which is open at the bottom and top
  • a pipe socket 1 Provided via a heat insulation 7, made of copper support flange 3, so that the pipe socket 1 is designed in this way as an expansion joint sleeve.
  • the pipe socket 1 is surrounded on its part a located above the support flange to form an air insulation gap 4 by a tubular shielding part 5 arranged concentrically to it, in the present case also consisting of copper, which, in order to avoid the formation of cold bridges, via heat-insulating fastening means, in FIG. left side, e.g. fixed in position relative to the expansion joint collar 1, 3 by means of a pair of silicone rubber spots 7 distributed over the circumference of the lower end face 6 of the shielding part 5.
  • a tubular shielding part 5 arranged concentrically to it, in the present case also consisting of copper, which, in order to avoid the formation of cold bridges, via heat-insulating fastening means, in FIG. left side, e.g. fixed in position relative to the expansion joint collar 1, 3 by means of a pair of silicone rubber spots 7 distributed over the circumference of the lower end face 6 of the shielding part 5.
  • the shielding part 5 is flanged in order to achieve a shape that is favorable in terms of flow and to drain any liquid that may be deposited on the outside of the shielding part 5 from the warm upper pipe socket part downwards, and extends to a very slight gap 11 to directly above the support flange 3rd
  • the air insulation gap 4 is at its upper, open end to prevent the entry of water or snow from the upper flanged end of the pipe socket 1 and the shielding part 5.
  • the casing 2 has the shape of the lateral surface of an octagonal truncated pyramid, but other shapes are of course also conceivable.
  • the same is closed at its upper end by means of a circumferential silicone rubber bead 7 'with simultaneous formation of thermal insulation and mounting between the pipe socket 1 and the shielding part 5.
  • the latter extends to a very slight gap 11 to immediately above the upward chimney end face 3a on which the shielding part 5 is supported by beads, so that moisture can escape downwards out of the air insulation gap 4, but on the other hand even when it is strong Wind flow the air in the interior of the air insulation gap has sufficient heat insulation.
  • the shielding part 5 in addition to the silicone rubber bead 7 'for better fixation at its lower end or at its pipe socket part protruding into the chimney can also be fixed with a few silicone rubber spots 7 on the chimney head.
  • the casing 2 is supported on the shielding part 5 via the support ribs 16, so that any cold bridge formation between the casing 2 and the pipe socket 1 is avoided.
  • This chimney cap shown in Figure 2 is to achieve an even greater insensitivity to the incoming wind over an even larger wind inflow angle range with a coaxially arranged to the outer jacket 2, truncated pyramid-shaped inner jacket 8, and the inner and outer jackets 8 and 8 respectively. 2 are provided in their side surfaces with flow openings 9, which for deflecting a wind flow entering through them into an at least approximately parallel to the opening plane in the interior of the inner or outer shell 8 or. 2 flaps 10 serving as flow deflection means are assigned, as is described in more detail in the non-prepublished EP-A 0294336.
  • the shielding part 5 shown on the left-hand side of FIG. 2 is heat-insulating at its lower end by means of a circumferential silicone rubber bead 7 ⁇ to avoid any cold bridge and by closing the lower end of the air insulation gap 4 connected to the support flange 3.
  • the upper end of the air insulation gap 4 is still connected to the outside atmosphere via a very slight gap 11.
  • 11 silicone rubber dots could be attached to several points of this gap in order to additionally fix the shielding part 5 at its upper end and avoiding any cold bridge between the cold shielding part 5 and the warm pipe socket 1 on the latter.
  • FIG. 2 An embodiment is shown in the right part of FIG. 2, in which the air insulation gap 4 is completely closed to the outside, forming an air insulation cushion is.
  • the shielding part 5 is hermetically sealed at its upper and lower ends, avoiding any formation of cold bridges between it and the pipe socket 1 to be kept warm during operation, by means of a simultaneously insulating, all-round silicone rubber bead 7 'and 7'.
  • the support flange 3 is here to avoid a cold bridge via thermal insulation 12 with the casing 13 of a chimney cover element, and the latter of its side facing the chimney head is provided with a heat-insulating insulation 13, which at the same time a part of the support flange 3 down extending pipe socket 1 surrounds heat insulation.
