Definitions

  • the present patent concerns flues for stoves and fireplaces in general and in particular concerns a new flue with jacket and spacers.
  • stoves and fireplaces in general for indoor heating is widespread.
  • the two most important component elements of said stoves or fireplaces are substantially the combustion chamber, inside which combustion of the combustible material, such as wood, coal or other, takes place, and the flue or chimney.
  • the flue or chimney in particular, has the function of conveying the combustion fumes out of the building.
  • Said combustion chamber and said flue are made of refractory materials which are resistant to heat and to the corrosive action of the acid combustion residues.
  • flues can be made of concrete, cast iron, asbestos cement or, preferably, stainless steel, the smooth walls of which facilitate ascent of the smoke and prevent adhesion of the soot.
  • stainless steel is able to withstand mechanical stress deriving from thermal expansion and sudden changes in temperature.
  • Flues have a preferably circular section which guarantees a better draught, since the smoke evenly laps the whole inner surface of the flue, thus heating it uniformly.
  • the flue can comprise a first exposed section, providing the connection between the stove or fireplace, positioned in the room to be heated, and the chimney, i.e. the section of flue embedded in the wall. It is preferable for said exposed section to be as short as possible to prevent excessive cooling of the fumes inside.
  • the practice of using the heat radiated by the exposed section of flue as an additional heating source is known.
  • the flue in fact, heated by the combustion fumes passing through it, radiates heat in the surrounding environment.
  • the main object of the present invention is to provide a flue that is adequately insulated.
  • a further object of the present invention is to prevent direct contact with the flue, protecting users from accidental bums.
  • a further object of the present invention is to ensure that the jacket can be fastened to the flue in a stable correct manner.
  • a further object of the present invention is to exploit the heat radiated by the flue, as an additional source of heating for the rooms in which the stove or fireplace is located.
  • a further object of the present invention is to constitute an external element which can also be used as a decorative element, not subject to the technical limits imposed by an ordinary single flue.
  • a further object of the present invention is to make installation thereof possible also on existing flues.
  • the present invention consists in its main parts of a flue, of known type, with preferably circular section and made of stainless steel or other material that can withstand not only the heat of the combustion fumes but also the corrosive action of the acid combustion residues.
  • the present invention comprises a further duct, or jacket, having section of any shape, for example corresponding to the shape of the flue section but with larger dimensions.
  • Said jacket and said flue are positioned coaxially so as to provide an air space between the cylindrical wall of the flue and the cylindrical wall of said jacket.
  • Said jacket is fastened to said flue by means of a plurality of spacers, with shape corresponding to the shape of the air space, i.e. annulus-shaped in the case of jacket and flue with circular section.
  • Each of said spacers is fixed between said flue and said jacket, i.e. between the outer wall of the flue and the inner wall of the jacket.
  • Said spacers therefore have the main function of maintaining said jacket in a position coaxial with said flue, so that the air space has a constant section.
  • Said air space also performs the important function of insulating the flue, thus preventing the combustion fumes from cooling excessively during ascent.
  • said jacket can be positioned so as to provide one or more apertures or air passages, for example near the base of the flue, where the connection with the stove or chimney is made, and/or near the top of the exposed section of flue, i.e. where said flue penetrates into the wall or ceiling.
  • Said jacket also has the important function of preventing accidental contact with the surface of the flue, which, during passage of the combustion fumes, reaches very high temperatures.
  • Said jacket also has an aesthetic function, particularly if applied, by means of said spacers, to existing flues, the outer surfaces of which may be worn due to prolonged use.
  • a further advantage deriving from the use of said jackets lies in that they can have any shape, while it is preferable for said flue to have a circular section to ensure a good draught.
  • Figure 1 shows one of said spacers, while figure 2 schematically shows the connection point between two adjacent sections of flue and jacket.
  • FIG. 3 shows the new invention fully assembled.
  • the flue (F) is a duct with a preferably circular section made of ordinary or stainless steel.
  • the jacket (C) is positioned coaxially to said flue (F) and has a shape corresponding to the section of the flue, but with larger dimensions. In this way, between said jacket (C) and said flue (F), an air space (K) is provided, inside which a flow of air (W) circulates.
  • said jacket (C) is fastened to the flue (F) by means of a plurality of spacers (A), each having a section substantially corresponding to the section of said air space (K).
  • said spacers (A) comprise a flat annulus (R), of dimensions such as to be inserted inside said air space (K), in a position substantially square to the longitudinal axis (X) of said flue (F) and said jacket (C).
  • each of said spacers (A) comprises a plurality of tabs (E, I) distributed in a perimeter fashion around both the smaller and larger diameters of said annulus (R).
  • said outer tabs (E) and inner tabs (I) are positioned square to the plane on which the annulus (R) lies, so as to adhere to the inner wall of the jacket (C) and to the outer wall of the flue (F), respectively.
  • Said tabs (E, I) are preferably provided with one or more holes (V) for the insertion of screws for fastening the spacers (A) to the jacket (C) and to the flue (F).
  • Said tabs (E, I) are preferably distributed uniformly along the larger and smaller circumferences of the annulus (R) of the spacers (A).
  • each of said spacers (A) preferably comprises at least 4-6 tabs (I) on the inner diameter and at least 6-8 tabs (E) on the outer diameter. This guarantees maintenance of the roundness, particularly of the jacket (C).
  • Each of said spacers (A) also comprises one or more apertures (S), provided on the annulus (R), to permit the circulation of air (W) inside said air space (K).
  • said jacket (C) is positioned so as to provide one or more apertures or air passages (P), for example between two adjacent sections constituting the jacket (C) or near the base of the flue (F), where the connection is made with the stove or fireplace (B), and near the top of the exposed section of flue (F), where said flue (F) penetrates into the wall.
  • P apertures or air passages
  • said flue (F) can have a circular section
  • said jacket (C) can have any section, for example elliptical, hexagonal, etc.
  • the outer perimeter of each of said spacers shall have a shape corresponding to the shape of said section, i.e. elliptical, hexagonal etc.
