Definitions

  • Reactors are already known comprising a tubular enclosure delimited between a tubular cylindrical jacket, a rear inlet wall with central opening and a front cup with outlet opening facing a deflector.
  • the enclosure is divided by an intermediate wall, with peripheral light for the passage of gases, into a combustion chamber and an outlet chamber.
  • the intermediate wall forming an obstacle for the combustion gases, creates turbulence promoting the mixing of the combustion elements and allowing complete combustion.
  • the object of the present invention is to remedy this by providing a reactor making it possible to obtain complete combustion, without emission of polluting agent, and providing, in addition, a reduction in yield losses and consequently a saving in fuel.
  • the means for turbulence the gases of the enclosure are constituted by a cylindrical ring of deflection of the gases, arranged between the cup of the enclosure and the deflector, coaxially with the enclosure, at a distance from the deflector , and so that its cylindrical wall is in the path of the gases returned by this deflector and generates a return depression of the gases from the hearth.
  • This ring performs three functions. The first is to brake the gas exit speed at the exit of the reactor to form in the enclosure a compression zone creating turbulence in this enclosure. Its second function is to deflect the gases coming from the deflector so that they take a path substantially parallel to the generators of the jacket of the enclosure and come against the hearth plate thereby ensuring a more uniform distribution of calories on the exchange surfaces. Finally, its last function is, by creating a vacuum, to suck up the gases circulating in the hearth but which have not yet given up all their calories to return them towards the exchange surfaces thereby improving the efficiency of the installation.
  • the device according to the invention not only makes it possible to remove unburnt gases, but also to improve thermal efficiency and, with equal calorific power, to reduce fuel consumption.
  • 1 generally designates the hearth delimited by heat exchange surfaces 2, 3 and 4 and by a hearth plate 5, and 6 designates the combustion chamber.
  • it is composed of a cylindrical tubular jacket 7, a rear wall 8 of refractory material having a central opening 9 for the passage of the nose 10 of the burner and finally an anterior cup 12 of frustoconical shape comprising a gas outlet orifice 13.
  • a deflector 14 In front of the cup, is disposed a deflector 14 of the same conicity and same outside diameter as the cup 12 and having a diametrical face 14a.
  • the means generating turbulence in the combustion chamber 6 are constituted by a cylindrical ring 15 disposed coaxially with the jacket 7 of the reactor between the cup 12 and the deflector 14. More precisely, this ring 15 is arranged near but at a distance from the deflector 14 and so that its wall is in the path of the gases as represented by the dashed line X.
  • This ring which has an internal diameter D greater than the external diameter d of the jacket 7, is carried by longitudinal lugs 16 also carrying the deflector 14.
  • These lugs are fixed to the cup 12 by an elastic connection constituted in this embodiment, by slots 17 covering inclined lugs 18 projecting perpendicularly from the cup 12. This arrangement makes it possible to keep the relative provision of elements, whatever the expansions and therefore whatever the temperatures prevailing in the hearth 1.
  • the jacket 7 is fixed to a wall 19 juxtaposed with the hearth plate 5 by threaded rods 20 integral with this jacket and passing through the hearth plate and the wall 19 to receive suitable nuts.
  • the hot gases leaving the orifice 13 of the enclosure 6 are returned by the deflector 14 in the direction of the ring 15.
  • the latter being in the path of these gases, exerts braking on them which tends to generate in the enclosure 6 a compression zone shown diagrammatically at 21 in FIG. 1.
  • This zone alone generates inside the enclosure the turbulences which are necessary to ensure the mixing of the unburnt substances with the gases hot and thus obtain the desired complete combustion.
  • the ring 15 also constitutes a deflector and returns the hot gases leaving the reactor in the direction of the hearth plate 5 by making them travel a path parallel to the jacket 7 but also parallel to other exchange surfaces.
  • This circulation is favorable to heat exchange and makes it possible to obtain a more uniform distribution of calories on the exchange surfaces while avoiding any condensation on these surfaces.
  • the depression created in the anterior zone 24 of the ring 15, ensures the return of the gases circulating in the hearth, gases which, as shown in arrow 23, mix with the hot gases to return to the exchange circuit before escaping through the flue 25.
  • This last aspect is particularly important since it alone makes it possible to reduce the yield losses due to the too rapid escape of hot gases, in a proportion of the order of 30 to 35%.
  • a piece 27 of ceramic fibers against the bottom 14a of the deflector is fixed a piece 27 of ceramic fibers, the retention of which is ensured by tabs 28.
  • the thickness of this piece is of the order of 12 mm. If the liquid fuel is badly sprayed on the nozzle, the turbulence may not be sufficient to allow good mixing with the air.
  • the part 27 then ensures complete combustion of the unburnt materials by contact of these with the fibers of the surface of the part 27, which become incandescent, as soon as they are turned on burner.
  • the ring 15 must have a length of 20 mm, an internal diameter D greater than the external diameter d of the jacket 7, and of the order of 30 mm, and be axially offset from the rear face of the deflector by a value of the order of 5 mm.
  • a compensation output is provided in the deflector 14 by an opening 26 made axially in the wall 14a of the latter.
  • the reactor according to the invention not only makes it possible to obtain perfect combustion of the gases without emitting pollutants, but also makes it possible to reduce the consumption of fuel, to eliminate the condensations on the surfaces. exchange and therefore increase the longevity of the fireplace.
