Definitions

  • the present invention relates to a heating device comprising a heat recovery unit.
  • Heating apparatuses which include an inlet for combustion air and a hearth under which is disposed a combustion chamber provided with a flue or flue gas evacuation duct.
  • the heat recuperators in the current chimneys are located at or around the hearth, in the heart and in the hood of the smoke evacuation duct.
  • the solid fuel gives off combustible gases which, in order to ignite, must be brought to a high temperature incompatible with this type of material.
  • the object of the present invention is to overcome the above-mentioned drawbacks by using an improved heating device.
  • the selom heating device of the invention comprises at least one inlet 1 for combustion air, a hearth 2 under which is placed a combustion chamber 3, receiving a heat recovery unit 4.
  • the gases burned in the chamber 3 are evacuated by at least one duct 5.
  • the device according to the invention is of the type of those receiving a solid fuel, but it is quite obvious that the arrangements described below can be applied to heating with liquid or gaseous fuels, or with heating appliances of the mixed fuel type.
  • the heater as shown in Figure 1 includes a combustion air inlet located in its upper part. This inlet opens into a large capacity enclosure 6 and can be partially or totally obstructed by a plate 7 this in order to regulate the flow of combustion air.
  • the hearth 2 is equipped with a grid 8 allowing. the communication of the enclosure 6 with the combustion chamber 3. On this grid is disposed the solid fuel 9 introduced into the appliance through an opening 10 situated above the hearth and provided with a folding closing flap I1.
  • the heating appliance In its lower part and in the combustion chamber 3 the heating appliance is provided with an ashtray 14 mounted on slides 12 receiving the combustion waste.
  • a space 13 opens out into the combustion chamber 3 and provided in its upper part with a pipe 15 connected to the exhaust pipe 5. smoke itself connected to enclosure 6.
  • the heat recovery unit 4 in which circulates a heat transfer fluid recovering the calories from the combustion in order to transfer them to a heating installation.
  • the heat recovery unit is mounted with sufficient clearance in the combustion chamber and in space 13.
  • the collector 4 is attached to the heater by any means known to the man of the art does.
  • This recuperator consists of at least two boxes connected to each other 4A and 4B which are housed respectively in the combustion chamber 3 and in space 13.
  • the casing 4A disposed between the ashtray 14 and the hearth 2 is parallel to it or slightly inclined towards the ashtray to facilitate the evacuation of the waste coming from the said hearth in the said ashtray.
  • the box 4A is provided at the free end with a tube 16 through which the heat transfer fluid such as gas or liquid is introduced.
  • the box 4B is provided at the upper end with a tube 17 which comes out of the heat transfer fluid.
  • the heat recovery unit consists of a box 4A to which are connected three boxes 4B in communication with each other and arranged in a space 13 formed between three vertical walls of the enclosure 7 and three vertical walls of the heater.
  • the boxes 4A and 4B are each provided with baffles 18 interior designed to increase the path of the heat transfer fluid so that it recovers during its passage through the recuperator A maximum of calories.
  • the heat from the hearth is directed by the phenomenon of reverse draft in the chamber 3 and in the space 13.
  • the combustion chamber 3 is equipped with at least one channeling means.
  • This means is constituted by a wall 19 substantially vertical and transverse to the exchanger 4A coming to be arranged between the upper wall of said recuperator and the hearth 2.
  • This wall is fixed to the recuperator 4A and to the hearth 2 by all known means and methods.
  • the wall 19 forming screen has a function to obstruct the t chamber 3 with the communication port 13 in the space volume between the top wall of the recuperator 4A and the fireplace so that the heat flow under the action of the reverse draft is channeled towards the front end of said exchanger and bypasses it.
  • the distance separating the front end of the exchanger 4A from the front wall of the heating appliance is greater than the distance separating the lateral sides of said exchanger from the corresponding lateral walls of the appliance so that the most of the heat flow under the action of reverse draft bypasses said end before being directed into space 13.
  • the discharge pipe 15 is provided with a maneuverable flap from the outside and more or less obstructing the passage of smoke.
  • the discharge pipe 5 at the outlet of the enclosure 6 may also be provided with a shutter which can be operated from the outside to partially or completely obstruct the orifice of communication with the said enclosure so as to obtain or not the reverse draft. .
  • FIGS.'3 and 4 is shown an open hearth heating appliance such as an apartment chimney operating on the principle of reverse combustion and provided with a heat recuperator of the same type as that previously described.
  • the chimney according to the invention comprises a hearth under which is disposed a combustion chamber 20 in communication with a vertical duct 21, placed in the reluctant opening into the hood.
  • the combustion chamber is delimited by two side walls 22, by a front wall 23 and on which is placed or fixed a horizontal hearth plate 24 provided with a transverse orifice, for example rectangular, receiving a grate 25 on which is placed the fuel located preferably near reluctantly.
  • the side walls 22 and the front wall 23 are advantageously made of refractory materials recalling the traditional appearance of chimneys.
  • the front wall 23 is provided with an orifice through which an ashtray 26 for recovering combustion waste is engaged in the fuel chamber.
  • the vertical duct 21 is formed by a recess in the counter-core covered by a vertical chimney plate 27 fixed to the said core against all known means.
  • the heat recovery unit 4 comprising a box 4A, housed in the combustion chamber, in communication with a vertical box 4B housed in the duct 21.
  • the box 4A is slightly inclined towards the ashtray to facilitate the evacuation of the combustion waste.
  • a flap 28 which can be operated from the outside more or less obstructing the said flue to regulate the chimney draft.
  • a plate 29 forming a screen so that the heat flow from the hearth bypasses the front end of said box.
  • the heat recovery unit 4 is mounted in a passenger compartment, constituted by metal sheets assembled to each other by any known means and methods comprising a combustion chamber in communication with a conduit.
  • This cockpit provided with a horizontal hearth plate with grid comes to rest or be fixed on the hearth of the chimney and to be pressed against the heart.
  • the box 4B substantially follows the shape of an isosceles trapezium, the largest base of which forms its lower side so that the said box has an exchange surface in its upper part less than its lower part to reduce heat losses at its upper part.
  • air is preferably used as the heat transfer fluid, which is introduced by means of an accelerator or a vacuum cleaner into the exchanger 4. At the outlet of the box 4B, this heated air is recovered by a channeling system to be distributed in the dwelling. It is obvious that any other heat transfer fluid can be used. This is how we can provide a heat recovery unit receiving a liquid such as water to supply a cumulus.
  • a heat recuperator with mixed heat transfer fluid for example air or water, can be provided.
  • the heat recovery unit can be equipped with baffles to channel the air flow and a coil in which the water circulates.
  • provision may be made in the combustion chamber and at the level of the grate an inlet of preheated combustion air in contact with the hearth to facilitate the ignition of combustible gases.
  • the heating devices as described operating on the principle of reverse draft allow a significant saving of fuel while increasing the heat output.
