Definitions

  • the invention relates to a turbulator for an exhaust gas conveyance tube in a heat exchange apparatus.
  • heat exchange apparatuses such as, for example, exhaust gas boilers for the production of hot water or of other vector fluids, which involve the presence of tubes designed for the conveyance of exhaust gases produced by combustion in adapted furnaces, inserted in a volume containing the fluid to be heated.
  • Tubes of this type are not exclusive to boilers, but can also be present in various different apparatuses in industrial cycles.
  • a turbulator Within such exhaust gas conveyance tubes an element known as a turbulator is often inserted, the specific function of which is to break up the boundary layer of the flow of exhaust gases which is in contact with the inner surface of the tubes, and a very common construction form of the turbulator element is constituted by a simple helix of metallic wire which is arranged so as to adhere to the inner surface of the tubes.
  • the aim of the present invention is to provide a turbulator element that optimally performs the function of creating turbulence in the flow of exhaust gases, so as to optimize the transmission of the heat between the exhaust gases and the fluid to be heated.
  • a turbulator for an exhaust gas conveyance tube in a heat exchange apparatus characterized in that it comprises at least two helices made of metallic wire, which are designed to be inserted in said tube so as to adhere to the inner surface thereof, are arranged side by side and are rendered mutually integral by means of at least one connecting element.
  • the reference numeral 1 designates the exhaust gas conveyance tube within which is present the turbulator 2 formed according to the known art from a single helix of metallic wire, inserted in contact with the inner surface of the tube 1, as highlighted by Figure 2 .
  • Figure 3 shows the turbulator 3 according to the invention which comprises two helices 3a, 3b that are substantially identical, made of metallic wire, arranged side by side and rendered integral by way of a connecting element constituted by the bar 3c welded thereto.
  • This turbulator 3 is very effective in preventing the formation of a boundary layer of the flow of exhaust gases in contact with the inner surface of the wall of the tube, and the turbulence that derives therefrom creates optimal conditions for the transmission of the heat between the exhaust gases and the fluid to be heated that surrounds the tube.
