Definitions

  • the invention is related to a chimney comprising a flue for burnt gases of a heating device and a flue concentric to said first flue, by which between both flues a ring shaped channel is formed for the discharge of ventilation gases.
  • a chimney is known from Dutch Patent Application 73,04218. This known chimney gives satisfaction for the discharge of burnt gas, for instance originating from a boiler of a central heating and of ventilation gases, for instance coming from spaces to be ventilated such as kitchens, the room in which said boiler is positioned, etc, which latter gases have a temperature that is the same or a little higher than the surrounding temperature.
  • the invention aims to remove said objections.
  • a third concentric flue is present in such a manner that a second ring shaped channel is formed for discharge gases of a second heating device.
  • the embodiment is such that the center channel serves for discharging the burnt gases with higher temperature, the first ring shaped channel serves for the discharge of burnt gases with lower temperature and the outer ring shaped channel serves to discharge the ventilation gases.
  • the known chimney is covered at the discharge side against entrance of rain by a cap having a diameter larger than that of the outer flue.
  • a cap having a diameter larger than that of the outer flue.
  • the central channel at its discharge end is closed by a cap shaped wire grate and a plate supported thereon, which grate is surrounded by said cap.
  • the ring shaped channels debouches in the ring shaped space between the wire grate and the cap.
  • the inner flue in said ring shaped space in the cap is surrounded by a frusto conical ring. The obliquely entering rain therefore is removed sidewardly and will flow away through the space between the lower edge of the cap and the outer wall.
  • the diameter of the smallest opening of the ring is larger than that of the cap shaped wire grate.
  • the burnt gases are able to flow out ⁇ wardly through said passage.
  • the single figure shows a vertical section of the chimney according to the invention.
  • the burning device not shown, for solid fuel such as a stove or- an open hearth is connected at 1 to the central channel 2 for burnt gas, the boiler of the central heating is connected at 3 on the first ring shaped channel 4 and the ventilation flue 5 is connected to the outer ring shaped channel 6.
  • the central gas flue 4 is covered by a cap shaped wire grate 7 on which a plate 1 is provided.
  • the combustion gas will flow sidewardly between the three stays 9 and the distance pieces 10 in a room 11 that is formed between the downwardly directed wall 12 of the cap and the discharge channel 2 for gases from the burning device and they subsequently may flow out upwardly.
  • both ring shaped channels 4 , 6 debouche
  • a conically truncated ring 13 is provided from which rain water can flow away and will flow through the room 11 between the wall of the cap and the outer wall of the outer flue 6 in which distance pieces 14 take care that the cap is well centered.
  • a ring shaped opening 19 is formed between the upper edge of the ring 13 and the circimferential wall of the cap 7.
