Definitions

  • the present invention relates to a fireplace that can be powered by solid or liquid fuels, comprising an enclosure having a combustion air inlet and a smoke outlet, said enclosure containing a heating body.
  • a first object of the invention is to allow the use in a home of this type of young woods, i.e. wood with a high content of combustible wet matter (more than 20%). It has indeed been shown that young wood from cuts made during the winter preceding that in which it is consumed, has a high calorific value which, in practice, is twice that of wood considered as dead wood. However, this high content of combustible wet matter requires special measures to ignite these woods.
  • Another object of the invention is to apply the principles which are at the base of the hearth according to the invention to the combustion, under analogous conditions, of fossil fuels, young or old as well as liquid fuels.
  • the hearth according to the invention comprises means for heating the fuel in order to extract the gaseous fraction therefrom in the form of hot gases which are directed by a set of conduits under a hearth on which is placed the solid fuel or spread the liquid fuel and which is intended to bring these fuels to a temperature at which the evaporation of said gaseous fraction is possible thanks to the heating of the aforementioned sole by the aforementioned hot gases .
  • the aforementioned hearth is arranged in an inclined manner, the lowest part being situated on the front side of the heating body, i.e. on the side which has the aforementioned combustion air inlet.
  • the aforementioned hearth is located, considering the direction in which the combustion air and the fumes circulate, upstream of at least one duct acting as a thermal condenser, ie .d. burner for unburnt gases intended to capture the aforementioned hot gases, said duct itself being located upstream of a duct which directs the hot gases under the aforementioned hearth.
  • a thermal condenser ie .d. burner for unburnt gases intended to capture the aforementioned hot gases
  • the above-mentioned sole is planar.
  • the aforementioned sole conforms, in part, to the shape of a truncated cone.
  • the aforementioned sole is made of a refractory material.
  • the aforementioned set of conduits consists of the perimeter space which remains between the aforementioned enclosure and the aforementioned heating body and which comprises, under the aforementioned hearth, a set of baffles arranged so as to distribute the hot gases along the aforementioned sole.
  • the set of conduits in which the aforementioned fumes and gases circulate, are equipped with means tending to delay the passage of the fumes and gases and are produced to cause the afterburning of the gases. hot flowing in the aforementioned conduits.
  • the hearth according to the aforementioned figures will be described in its design as a wood hearth, but its adaptation to a fuel will also be the subject of a description with particular reference to FIG. 4.
  • the hearth according to the invention and represented in FIGS. 1, 2 and 3 is a solid fuel hearth and, in the examples described, it will essentially be a question of a fuel constituted by wood and in particular young wood.
  • the hearth consists of an enclosure 1 which has, in a manner known per se, a combustion air inlet which has not been shown in the schematic drawings but which can be located in any suitable place, generally in the front face or before the enclosure.
  • This same enclosure has a smoke outlet designated by reference 2.
  • a heating body 3 Inside the enclosure 1 is mounted a heating body 3. Between the enclosure 1 and the heating body 3 there is a perimeter space which is subdivided into a vertical perimeter space 4 and a horizontal perimeter space 5.
  • the lower and front part of the hearth is incidentally occupied by an ashtray 6.
  • a fundamental and essential element of the invention consists of a hearth 7 which in reality constitutes the essential of the lower part of the enclosure 1.
  • the sole 7 may be made of a diffusing refractory material, of steel or ceramic, which is particularly advantageous, and be in a flat form and inclined towards the front and as shown in FIGS. 1 and 2.
  • Sole can also take shape of a truncated cone and then appear as shown under the reference 7 ′ in FIG. 3.
  • the sole 7 has a flange 9 for retaining the fuel 8.
  • the floor 7 (or 7 ′) is located upstream of a duct 10 acting as a thermal condenser.
  • the evaporation of liquid, combustible materials occurs essentially upstream of the conduit 10, while the diffusion of the calories necessary for this evaporation occurs downstream of the same conduit 10.
  • This conduit 10 directs the gases and the fumes to a space 11 located under the hearth 7.
  • the hot gases already brought to a temperature which can be considered high, brings the hearth 7 to this same temperature. It is easy to imagine that it will cause significant heating of the fuels deposited on the hearth.
  • kindling or dry wood can be used because, at this stage, the temperature of the hearth is not such as to cause the fuel wood to heat up.
  • the gases will circulate towards the vertical perimeter spaces 4 to then reach the horizontal perimeter spaces 5 located above the heating body 3 and immediately upstream of the outlet 2 intended for the exhaust of the fumes.
  • the conduits in which the gases circulate may have grooved walls. or provided with baffles, the afterburning of unburned so as to cause a remarkable increase in the heating capacity of green woods. Under these conditions, the heating capacity of these woods is greater than that of dead or dry woods.
  • the green woods contain these materials in significant quantities, they are extracted more quickly and more completely from firewood placed on a hearth which is itself quickly brought to a high temperature by the gases circulating in space. 11 under the hearth before reaching the smoke outlet 2, after having crossed the vertical and horizontal perimeter spaces 4 and 5 respectively.
  • the fuel supply can be done by hoppers and worms as shown in Figure 3.
  • the fuel which is under particles of smaller size is represented by the reference 12 and the orifice of the hoppers by the reference 13.
  • FIG 4 is shown a supply of liquid fuels 14 which reaches a sole 7 sole.
  • the flow of liquid fuel can obviously be controlled and its flow on the bottom 7 sole causes the effects described above in the sense that the liquid fuel evaporates with or without flame, the unburnt is taken up by the pipe 10 making as a thermal condenser to circulate in the same way in a baffle circuit and heat the bottom 7 sole. After instillation of the oxygenated oxidant, the unburnt products are transformed, at the level of the ashtray 6, into a so-called post-combustion phase.
  • FIGS. 5 and 6 the arrangement of a number of baffles 15 and of a deflector 16 has been shown diagrammatically. These elements are intended to prolong the contact between the hot gas and the floor 7 (in other forms of realization of the soles 7 ′ and 7 ⁇ ). It is obvious that both the surface of the baffles and that of the internal wall of the various conduits can be smooth or provided with asperities delaying the passage of the hot gases and therefore prolonging the contact of these with the walls to be heated.
