  • the air to be recycled and to be heated passing through the corridors 18 drawn from inside the room where the hearth is located is mixed with fresh air drawn from outside, the latter penetrating into the rear sheath formed by the reluctant 30 and the rear face 10 of the box 1 by means of openings 27 arranged on the vertical faces 9 or 10 or on the lower face 7 according to the position of the supply duct of said outside air, the openings 27 then being arranged by removal of the material facilitated by an initial pre-sinking during manufacture.
  • a groove 28 is arranged to receive the lower end 29 of the counter-core 30 shown in FIG.
  • the groove 28 is aligned with the end of the fallen edge 5 of the box 1 so that the counter-core 30 is vertical, the latter being immobilized in the groove 28 and resting on the fallen edge 5 on which it can be immobilized by means of brackets and bolts not shown, at the rear the reluctant is provided with pins 31 or projecting teeth contained in the sheath 32 arranged by the offset of the reluctant 30 of the rear face 10 of the box 1, the sheath 32 being intended to allow the passage of the mixture of the fresh air and the air to be recycled so that a heat exchange takes place between these and the metal elements before its diffusion through the openings 6 at the outlet of which it is channeled and directed by suitable sheaths.
  • the hearth plate 16 is provided with grooves 33 on the upper face, vertically and on the front face of the grooves 34 are arranged on the counter-core 30 as an extension of the grooves 33.
  • the universal hearth comprises to generate an open hearth, an envelope box 1, a hearth plate 16 and reluctantly 30, on the side faces 9 bearing on the lateral sides of the hearth plate 16 and reluctantly 30 is attached a lining 35 of prefabricated traditional refractory material, the outside face of said lining being aligned with the end of the fallen edges 4, the discharge openings 6 arranged on the fallen edges 4 being closed by the lining 35, only the sheath 32 allows the circulation of the mixture of air to be recycled and fresh air drawn from outside, the air to be recycled passing through the corridors 18 and 19, the air passing through the corridor 19 being directed towards the corridor 18 through the opening 11b arranged by removal of the material delimited by the pre-sinking 11a, the openings 21 arranged on the hearth plate being closed.
  • the element 37 on its face 37a is provided with a groove 40 near the connection of the wings 37a and 37b, the face 37b being offset from the glazing 39 in order to allow the diffusion of the heated air against the glazing.
  • the element 37 is made integral with the side plates 36 by means of bolts for example.
  • a metal deflector 42 is fixed by any suitable means on the face 37b of the element 37.
  • the offset of the side plates 36 of the faces 9 of the box 1 generates a sheath 47 inside which are contained the pins 48 or projecting teeth which are provided with said plates 36 according to a distribution as previously described in a staggered outline and / or sinusoidal, in order to perfect the heat exchange of the mixture of fresh air and to recycle with the metallic elements, said heated air being evacuated through openings 6 and recovered in a collector 49 adjusting on the fallen edges 4 and 5 facing the openings 6, the collected air is then ventilated through ducts 50 in the room or rooms to be heated.

  • the glazed closed hearth differs from the hearth shown in FIG. 6 by adding a drain 76, the latter resting on the partial returns 4 and 5 of the box 1, its immobilization is obtained thanks to the upper parts 77 side faces projecting vertically from the fallen edges 4 and 78 of the fallen edge 5, the front face 79 of the hood fitting into the groove 40 formed on the wing 37a of the upper element 37, the evacuation of the heated air is produced by means of flexible ducts 50a leaving the openings 6 towards the part or parts to be heated.
  • the low metal fuel support grid of various shapes can be replaced by an identical metallic element formed by pipes in which a heat-transfer fluid circulates which allows a complementary calorific sample generating recovery systems. mixed air and water heat.
  • the flexible ducts 50a for evacuating the new heated air or for recycling are arranged so that they are not in contact with the burnt gases to ensure their perfect resistance over time.
  • the part of the sheaths 50 which passes through the exhaust pipe for the burnt gases and therefore bathed by the said gases is made up of rigid metallic elements of appropriate resistance up to passage of the deflector 42, the end portion of said sheaths 50a being protected after this deflector, it is possible to use flexible adjustable sheaths fitted into the elements 50 which allows instant decoupling and disassembly of the hearth, the flexible end portion of the evacuation sheaths staying in place.
