Definitions

  • the present invention relates to a device for recovering calories in an open or closed fire, device of the type in which the fumes and exhaust gases pass through heat exchange tubes.
  • the invention also relates to a method for producing such a device.
  • the common denominator of all these devices is to have tubes of all kinds in the passage of smoke and exhaust gas from the batteries, the heat exchange surfaces being more or less optimized from one device to another. In the same way, the shapes and relative positions of the tubes were varied to satiety.
  • the object of the present invention is to overcome these drawbacks.
  • this result is obtained with a device of the type described above, characterized in that it replaces the flue of the chimney and in that the heat exchange tubes are embedded in a material forming an accumulator heat.
  • the accumulation produced in the accumulator material produces a thermal buffer, which allows better regularity of heating.
  • the accumulator material may be of any known type compatible with the intended application, for example a refractory concrete or any other material using a binder. It can also be composite.
  • the device will be produced directly on site from a metal drain. box and comprising vertical or inclined organ tubes on the horizontal and in this case converging towards the center of the drain, the accumulator material being poured directly into the box around the exchanger tubes.
  • the tubes will be replaced by reservations made in the accumulator material when it is poured, the reservations being withdrawn later after drying of the refractory material.
  • the refractory mass is heated by the passage of smoke in the tubes.
  • a considerable and well distributed exchange surface is obtained, since as many tubes can be placed as desired.
  • the accumulated heat can be statically rejected or forced by turbine.
  • the rejection takes place for example by upper orifices or more advantageously by a multitude of pipes passing through the refractory material and emerging in the upper part on a collector connected to the outside of the device.
  • the air will circulate in the pipes by natural convection.
  • the recuperator of the invention can be placed for example on a very thick hearth made of refractory concrete designed on the same principle, that is to say in which the legs have air circulation pipes, or even very advantageously on a closed hearth.
  • the hearth is generally provided with peripheral air circulation ducts, the circulation operating by natural convection, which allows a first recovery of calories on the refractory side walls of the hearth before the air reaches the level of the device of l 'invention.
  • the tubes (3) are preferably distributed in organs or batteries over the entire volume of the device (2).
  • the tubes (3) are embedded in a refractory material (5), for example refractory concrete.
  • the tubes may be metal tubes integral with the box (6) of the recuperator (2), or be formed during the pouring of the refractory material by providing in it reservations, for example with expanded polystyrene or any other similar material which may be removed after setting of the concrete.
  • a part of the reservation elements can even be left in place, these being consumed from the first fire to release the tubes. It will suffice that at least one of the tubes is released before starting the fireplace for the draft.
  • This embodiment is the simplest mode of implementation of the device of the invention and its manufacturing process.
  • the calories accumulated in the refractory mass will be extracted by a fluid circulation, preferably from the ambient air circulating by natural convection.
  • the pipes (7) will preferably be arranged over the entire periphery of the refractory mass and will converge at their upper part towards a hot air recovery manifold (8) connected by an orifice (9) to the circuit. of use.
  • the pipes (7) will extend into the jambs of the chimney, the air being extracted in the lower part of the chimney.
  • the refractory mass can be made from prefabricated stackable elements, but preferably it will be cast on site by the user or the installer, in accordance with the method of the invention.
  • the invention finds a particularly advantageous application in combination with a closed hearth.
  • the closed hearth and the box can form an assembly which is placed as such in a chimney, after pouring the refractory.
  • a device for slowing down gases and fumes, of the register type, regulating the outlet flow rate of fumes and gases and especially making it possible to increase the exchange time at the device of the invention will be provided in the flue pipe.
  • the part upper thereof may, instead of being metallic, simply be made of a consumable material on which the accumulator material will be poured. When it has solidified, the consumable part will disappear on first use. This also prevents formwork.
  • the accumulator assembly can be prefabricated, for example made of stackable layers.
  • the tubes (3) To optimize the conditions for sweeping the tubes of the device, provision will be made for the tubes (3) to open into a funnel-shaped chamber, only one of the tubes (3) being in the vertical axis and in the center of this chamber. , in direct alignment with the duct (4). So all the soot will essentially fall into one tube.
  • the pipes can be fixed directly against the walls of the hearth, passing first below the hearth, then against the bottom before coming into the recuperator.
