Definitions

  • the present invention relates to a termination device for double wall smoke.
  • a double-walled flue is intended to evacuate the combustion gases, on the one hand, and to supply combustion air, on the other hand, one or more heating said to be sealed combustion, with liquid or gaseous fuel.
  • a so-called sealed combustion heater does not draw air from its direct environment but at a distance from where it is installed.
  • the air is generally taken near the place, for example the exterior of a building, where the fumes produced by combustion can be exhausted. That’s why he has been proposed, in the case of heaters with remote combustion air source to use a double walled pipe with concentric pipes in which a pipe inside conveys the smoke to be evacuated and an outside pipe conveys the combustion air to the heater using the annular space between the walls of the pipe inside and outside pipe.
  • Today's double-walled flues are designed to so that a termination part is, for example, on the roof of a building extends vertically, the inner pipe leading upwards to allow the evacuation of combustion gases.
  • the outer pipe also opens upwards, but its opening is below the opening of the pipe outside, so that the annular space forming the air intake opening is in below the opening of the inner pipe forming a gas exhaust port combustion.
  • the flue generally includes a protective cap installed above the opening of the inner pipe, so as to protect this opening while allowing the evacuation of combustion gases.
  • the smoke flue may also include a bell attached above the pipe opening outside so that the air sucked in through the annular opening between the inner pipe and the outside pipe enters from below the bell.
  • a first problem posed by known double-walled flues comes from the fact that the combustion gas discharged upwards through the opening of the pipe interior can nevertheless mix with the aspirated oxidant gas. This mixture can occur even if the oxidant gas is sucked under a bell.
  • a second problem with known double-walled flues comes from the fact that the humidity present in the relatively hot gases evacuated by the inner pipe can condense and freeze when these gases are suddenly cooled when arriving outside. When the temperature is low, a heap of ice can form on the duct. On the one hand, such a mass of ice can hinder the operation of the duct, for example by preventing air from entering the duct, and, on the other hand, create other problems like falling ice.
  • the present invention particularly relates to a double flue wall to solve the problems that have just been mentioned.
  • the present invention relates to a flue termination device double-walled heater, said flue comprising a inner pipe conveying the smoke to be evacuated and an outer pipe conveying air oxidizer to the heater using the annular space between the walls inner pipe and outer pipe, characterized in that said device termination includes an inner pipe and an outer concentric pipe, respectively extending said inner pipe and said outer pipe of said conduit, in that said inner pipe opens upwards so that its end upper form of smoke outlet, in that said outer pipe surrounds said inner pipe over substantially the entire height of the latter, and in that a combustion air inlet means is provided on the periphery of said external pipe to a height such that said air inlet means is below and at a distance of said smoke outlet means.
  • a crown obstructs the annular space between said inner and outer pipes above said combustion air inlet means.
  • This crown or obturation ring allows the air flow to be directed downwards and to avoid air rises.
  • a first bell element obstructs the space annular between said inner and outer pipes at the upper end of said outer pipe.
  • said first bell element is fixed by interlocking with said inner pipe.
  • said first bell element is fixed by crimping simultaneous of its wall and the wall of said inner pipe.
  • the annular space between said interior and exterior pipes is filled with thermal insulation in an area starting above said means combustion air inlet and going to its upper end.
  • said air inlet means consists of a plurality of holes made on the periphery of said outer pipe.
  • a second bell element is fixed by its upper part at the periphery of said outer pipe, just above said air inlet means, so that said second bell member extends around the outer pipe in look of said air inlet means.
  • the air inlet means is protected, the air sucked in by the inlet means of air entering from below the bell.
  • said second bell element is fitted onto said pipe outside.
  • said second bell element is fixed by crimping simultaneous of its wall and the wall of said outer pipe.
  • said smoke outlet means is surmounted by a means forming an anti-refoulement cap comprising a ferrule surrounding said smoke outlet means and a helmet disposed above said ferrule so that smoke escapes between the upper end of said ferrule and the periphery of said helmet.
  • said helmet comprises a lower wall of shape tapered tapering towards the bottom which is opposite said outlet means fumes.
  • a frustoconical wall narrowing upwards is formed around the upper part of said inner tube, the angle of inclination of this wall being opposite the angle of inclination of said lower shaped wall frustoconical of said helmet.
  • said helmet consists of an upper wall and a lower wall, an empty compartment or filled with thermal insulation being provided between these two walls.
  • This insulating compartment helps prevent condensation from forming under the hat helmet.
  • said helmet is of a size such that the periphery of said helmet constitutes the part of said termination device furthest from the axis of said termination device.
  • condensation droplets that can eventually form at the level of the periphery of the helmet or drops of water from rainwater falling on the top of the helmet are far enough away from the areas that should be protect from possible ice formation.
  • the present invention applies to a double-walled flue for a space heater distant combustion air source combustion.
  • a conduit includes a hose interior conveying smoke to the exterior of a building, the air intended to supply the heater circulating from the outside of the building to the heater heating, in the annular space created between the inner pipe and the outer pipe.
  • a conduit is made up of several conduit elements placed end to end. end.
  • the present invention relates to the terminal duct element, a part of which provided with smoke outlet and combustion air inlet means is located outside the building.
  • a terminal duct element 1 comprises overall an inner pipe 2 open at its upper end forming means of smoke outlet 3, an outer coaxial pipe 4 provided with an air inlet means 5 located in an air intake area located some distance below the smoke outlet zone, a bell 6 fixed to the periphery of the outer pipe 4 at the level of the air intake zone, a bell 16 fixed to the periphery of the inner pipe to close the gap between the interior and exterior pipes from above, and a set 8 covering the smoke outlet zone forming an anti-repression cap consisting of a ferrule 33 surmounted by a helmet 35.
  • the inner 2 and outer 4 pipes are each of generally cylindrical shape circular.
  • the outer pipe 4 has a diameter greater than the diameter of the pipe interior 2 so as to leave an annular space 9 between the interior pipe 2 and the external pipe 4 sufficient to allow the supply of combustion air to the heater.
  • the inner pipe 2 is longer than the outer pipe 4 and exceeds the latter in the lower part of the terminal duct element 1 which facilitates the nesting of the latter on the flue.
  • This pipe interior 2 includes at its lower end a re-entrant edge 21. The end upper of the inner pipe 2 opening upwards forms the exit zone of the smoke 3.
  • the outer pipe 4 has a tuck-in edge 10 at its lower end. above which is a rod 11 projecting outwards.
  • This rod 11 is intended to serve as a support on which comes the upper end of the outer pipe of the flue, the part located between the rod 11 and the inside edge 10 being adapted to come and fit into this outside pipe of the flue.
  • Two ways to fixing with nuts 7 crimped at the same height, diametrically opposite, on the pipe 4 allow the terminal duct element 1 to be fixed to a roof flashing 45, as can be seen in FIG. 5.
  • a combustion air inlet means 5 consists of a plurality of holes formed around the outer pipe 4. This set of peripheral holes defines an air intake means or air intake 5 which is at a certain distance from the upper end of the terminal duct element 1. This distance is provided so that the air inlet zone 5 is as far as possible from the air outlet zone fumes 3.
  • the air inlet zone 5 is located near the upper end of the frustoconical skirt 48, in the lowest possible position allowing a outside air intake.
  • This rod 12 has two functions. First of all, it is used for crimping the bell 6 on the outer pipe 4 as will be seen later. Then, it serves as a support for a crown 19 allowing the obturation of the space annular 9 above the combustion air inlet means 5.
  • a rod projecting outwards serving as a support for the bell 16 adapted to obstruct the annular space 9 between the interior and exterior pipes above the exterior pipe.
  • the annular space 9 between the interior and exterior pipes is filled with thermal insulation in the area between the ring 19 and the end top of the outer pipe 4 covered by the bell 16.
  • the bell 6 comprises at its top a first cylindrical part of diameter slightly greater than the diameter of the outer pipe 4 so as to allow a nesting of the bell on the latter then, downwards, a flare of frustoconical shape 14 then a second cylindrical part 15 on which is formed a recessed inward rush to prevent the intrusion of volatile in the air intake means and stiffen the bell at its low end.
  • the upper cylindrical part allows, as described below, fixing the bell to the periphery of the outer pipe, just above the air intake zone, so that the second cylindrical part 15 extends around the outer pipe opposite the air inlet holes 5, at a sufficient distance to allow the passage of air under the bell.
  • the fixing of the bell 6 on the outer pipe is done by fitting the pipe outside 4 in the bell 6 so that the outside wall of the pipe is pressed against the inner surface of the upper cylindrical part of the bell, then by crimping of this cylindrical part in the rod 12.
  • the crimping is carried out at the by means of a tube crimping device adapted to surround the pipe.
  • the bell 16 includes at its top a first cylindrical part 20 of diameter slightly greater than the diameter of the pipe interior 2 so as to allow the bell to fit on the latter, then, downwards, a tapered flare 18 then a second cylindrical part 17 which rests on the rod 13 of the outer pipe.
  • the upward tilt of the wall 18 contributes to improving the aerodynamic performance of the anti-repressor cap.
  • the fixing of the bell 16 on the inner pipe is done by fitting the inner pipe 2 in the bell 16 so that the outer wall of the pipe is pressed against the inner surface of the cylindrical part 20, then by expansion of the pipe inside.
  • the expansion is carried out by means of a tube expansion device that we introduce into the pipe.
  • Fig. 2 shows the assembly of the inner pipe and the bell before expansion
