Definitions

  • the present invention concerns the sector of room heating and in particular it concerns a new flue equipped with heat exchanger for heating rooms.
  • These stoves essentially comprise a furnace and are provided with a flue for the outflow of flue gases.
  • the heat generated by the combustion process is partly radiated by the stove and partly transported by the flue gases, so that even the flue heats up and radiates a certain quantity of heat.
  • the subject of the present patent is a new flue that uses the heat transported by the flue gases to heat the room better.
  • the new flue comprises, in its main parts, two concentric tubes, one of which is internal and through, while the other is external and closed at the ends and is provided with two connection openings (unions).
  • Each one of the two openings of the external tube is positioned on the lateral surface of said tube, near one of its ends.
  • a fan, or another forced ventilation means is provided to draw the air from the zone around the stove and blow it into the lower opening.
  • a helical foil is provided between the external and the internal tube to create a forced path for the blown air, between the two tubes and from one opening of the external tube to the other.
  • the new flue constituted as described above replaces completely or partially the flue positioned directly on the stove; the upper outlet of the internal tube of the new flue is connected with the remaining part of the flue that conveys the flue gases towards the outside.
  • the air blown in between the internal and the external tube follows the entire spiral-shaped path defined by the foil positioned between the two tubes and flows out through the upper opening.
  • the air that has been blown in receives heat from the internal tube, so that it will heat the room when it flows out of the upper opening of the new flue.
  • the new flue constructed as described above, makes it possible to recover part of the heat that otherwise would be dispersed towards the outside and heat the room in which the stove is positioned or even another room.
  • the flue gases are not negatively affected by the temperature decrease, since the quantity of heat still transported by said gas does not prevent the stack effect.
  • the air heated by means of the new flue can easily heat another room not directly exposed to the presence of the stove.
  • the figure shows the new flue, in partial section, comprising an internal tube (1) into which the flue gases flow, an external tube (2) concentric with the internal tube (1), a helical foil (3) included between the external tube (2) and the internal tube (1).
  • the ends of the external tube are closed, except for two openings (2.1, 2.2) - the lower opening (2.1) and the upper opening (2.2) provided on the lateral surface of the external tube (2) itself.
  • the air if necessary blown by a fan, flows into the lower opening (2.1), follows the spiral-shaped path touching the internal tube (1) and heating up, then flows out of the upper opening (2.2) at increased temperature.
