Abstract (en)
Flue for stoves or similar equipment, comprising two concentric tubes (1,2), one of which (1) is internal and through, while the other (2) is closed at the ends and provided with two openings (2.1,2.2) on its lateral surface; a helical foil (3) is positioned between the two tubes (1,2), creating a spiral-shaped forced path to be followed by the air between the lower and the upper opening of the external tube (2). A fan or another forced ventilation means may be provided to draw the air and blow it in through the lower or upper opening (2.1,2.2). This makes it possible to recover part of the heat, which otherwise would be dispersed towards the outside, in order to heat the room in which the stove is positioned or even another room. <IMAGE>
