Definitions

  • the present invention relates to a termination device for double-walled smoke duct.
  • a double-walled smoke duct is intended to evacuate the combustion gases, on the one hand, and to supply combustion air, on the other hand, one or more heaters said to sealed combustion, liquid or gaseous fuel.
  • a so-called sealed combustion heater does not take air in its direct environment but away from where it is installed.
  • the air is usually collected near the place, for example the exterior of a building, where the smoke produced by the combustion can be evacuated. That is why it has been proposed, in the case of heaters with remote combustion air source to use a double-wall pipe with concentric pipes in which an inner pipe conveys the fumes to be evacuated and an outer pipe vehicle the combustion air to the heater using the annular space between the walls of the inner pipe and the outer pipe.
  • Existing double-walled flues are designed so that a termination part, for example, is on the roof of a roof. building extends vertically, the inner pipe opening upwards to allow the evacuation of combustion gases.
  • the outer pipe also opens upwards, but its opening is below the opening of the outer pipe, so that the annular space forming the air inlet mouth is below the opening of the inner pipe.
  • a flue gas outlet forming a flue gas outlet.
  • the flue generally comprises a protective cap installed above the opening of the inner pipe, so as to protect this opening while allowing the evacuation of combustion gases. Such a device is described by the document US Patent 3376834 -AT.
  • the flue may also include a bell attached to the top of the outer pipe opening so that air drawn through the annular opening between the inner pipe and the outer pipe enters from below the bell.
  • a first problem with known double-walled flue pipes is that the flue gas discharged upwards through the opening of the inner pipe can nevertheless mix with the aspirated combustion gas. This mixing can occur even if the oxidizing gas is sucked under a bell.
  • a second problem with known double-walled flue pipes is that the moisture in the relatively hot gases discharged from the inner pipe can condense and freeze when these gases are suddenly cooled to the outside.
  • a pile of ice may form on the pipe.
  • Such a pile of ice can, on the one hand, interfere with the operation of the duct, for example by preventing the arrival of air in the duct, and, on the other hand, create other problems such as falling ice.
  • the present invention particularly relates to a double-walled smoke duct to solve the problems just mentioned.
  • the present invention relates to a double-walled smoke duct termination device for a heating appliance, said flue comprising an inner pipe conveying the flue gases to be discharged and an outer pipe conveying the combustion air to the heating appliance using the annular space between the walls of the inner pipe and the outer pipe, characterized in that said termination device comprises a concentric inner pipe and a concentric outer pipe, respectively extending said inner pipe and said outer pipe of said pipe, in that said pipe interior opens upwards so that its upper end forms the average outlet smoke, in that said outer pipe surrounds said inner pipe over substantially the entire height of the latter, and that combustion air inlet means is provided on the periphery of said outer pipe at a height such that said air inlet means is below and away from said flue outlet means.
  • the outer pipe continues to surround the inner pipe above the air inlet means to the smoke outlet means, the annular space between the walls of these pipes can serve as an insulating compartment. for thermally isolating the inner duct from the outside air and is filled with a thermal insulator in a zone starting above said combustion air inlet means and up to its upper end.
  • a first bell member obstructs the annular space between said inner and outer pipes at the upper end of said outer pipe.
  • a ring is obstructing the annular space between said inner and outer pipes above said combustion air inlet means.
  • This crown or sealing ring makes it possible to direct the flow of air downwards and to prevent upwelling.
  • said first bell-shaped element is fixed by interlocking with said inner pipe.
  • said first bell-shaped element is fixed by simultaneous crimping of its wall and the wall of said inner pipe.
  • said air inlet means consists of a plurality of holes formed on the periphery of said outer pipe.
  • a second bell-shaped element is fixed by its upper part to the periphery of said outer pipe, just above said air inlet means, so that said second bell-shaped element extends around the outer pipe in look at said air inlet means.
  • said second bell-shaped element is fitted on said outer pipe.
  • said second bell-shaped element is fixed by simultaneous crimping of its wall and the wall of said outer pipe.
  • said smoke outlet means is surmounted by an anti-reflector cap means comprising a ferrule surrounding said smoke outlet means and a helmet disposed above said ferrule so that the smoke escapes between the upper end of said shell and the periphery of said helmet.
  • said helmet comprises a bottom wall of frustoconical shape tapering down which is opposite said smoke outlet means.
  • a frustoconical wall tapered upwardly is formed around the upper part of said inner tube, the angle of inclination of said wall being opposite to the angle of inclination of said frustoconical lower wall of said helmet .
  • said helmet consists of an upper wall and a lower wall, an empty compartment or filled with a thermal insulator being formed between these two walls.
  • This insulating compartment helps to prevent the formation of condensation under the helmet of the hat.
  • said helmet is of a size such that the periphery of said helmet constitutes the part of said termination device farthest from the axis of said termination device.
  • condensation droplets that may possibly form at the periphery of the helmet or drops of water from the rainwater falling on the top of the helmet are sufficiently far from the areas that should be protected from a possible ice formation.
  • the present invention is applicable to a double-walled flue for a combustion heater having a remote combustion air source.
  • a duct comprises an inner pipe conveying the fumes to the exterior of a building, the air intended to supply the heating apparatus flowing from the outside of the building to the heating apparatus, in the annular space created between the inner pipe and the outer pipe.
  • a conduit consists of several conduit elements placed end to end.
  • the present invention relates to the terminal conduit element, a part provided with smoke outlet means and combustion air inlet is located outside the building.
  • a terminal pipe element 1 generally comprises an inner pipe 2 open at its upper end forming a smoke outlet means 3, a coaxial outer pipe 4 provided with an air inlet means 5 located in a zone of air intake located at a distance below the smoke outlet zone, a bell 6 fixed to the periphery of the outer pipe 4 at the air inlet zone, a bell 16 fixed to the periphery of the inner pipe for closing from above the gap between the inner and outer pipes, and an assembly 8 covering the smoke outlet zone forming an anti-reflector cap consisting of a shell 33 surmounted by a helmet 35.

  • a combustion air inlet means 5 is constituted by a plurality of holes formed at the periphery of the outer pipe 4. This set of peripheral holes defines an air inlet or air intake means 5 which is located at a distance from the upper end of the end duct element 1. This distance is provided for the air inlet zone 5 to be as far as possible from the smoke outlet zone 3. As well as we see it well on the Fig. 5 when the terminal duct element 1 is mounted on the roof of a building, passing through a frustoconical skirt 48 of a roof flashing 45, the air inlet zone 5 is close to the upper end. of the frustoconical skirt 48, in the lowest possible position allowing an intake of outside air.

  • the upper cylindrical portion allows, as described below, the attachment of the bell to the periphery of the outer pipe, just above the air inlet zone, so that the second cylindrical portion 15 s extends around the outer pipe facing the air inlet holes 5, at a distance sufficient to allow the passage of air from below the bell.
  • the fixing of the bell 6 on the outer pipe is done by interlocking the outer pipe 4 in the bell 6 so that the outer wall of the pipe is pressed against the inner surface of the upper cylindrical part of the bell, and then by crimping this cylindrical part in the rod 12.
