Definitions

  • the object of the present invention is a silencer for gas wall-mounted boiler, for example a condensing boiler, according to the preamble of the main claim.
  • a gas wall-mounted boiler comprises a structure containing a burner thereat a mixture of gas and air arrives through a duct connected to a fan.
  • the latter is functionally associated to a mixing organ or member thereat the gas and the combustion air arrive.
  • an expansion vessel connected to the heating circuit apt to compensate the increase in the water volume due to its temperature variation.
  • the object of the present invention is to offer an improved expansion vessel for a gas wall-mounted boiler apt to allow a reduction of the whole sizes of the latter.
  • the object of the invention is to offer an expansion vessel of the mentioned type allowing the correct positioning of the other components of the burner within the structure of the latter.
  • Another object is to offer an expansion vessel of the mentioned type having a high mechanical resistance to the deformation.
  • figure 1 shows a gas wall-mounted, for example condensing, boiler 1 comprising a structure or outer casing 2, wherein a burner 3 is placed thereat a mixture of air and gas arrive through a mixing duct 4.
  • the latter is connected to a valve 5, in turn connected to a mixing organ or member 6, known in itself, connected to a gas duct 7.
  • an expansion vessel 9 is provided, with function known in itself, connected to the heating circuit of a house wherein such boiler operates.
  • the expansion vessel 9 comprises a box-like body 12 having peripheral walls 16 and 17, an upper wall 18, a lower wall 19 and a pair of front and rear walls 20 and 21 having larger surface extensions than those of the other above-mentioned walls 16 to 19.
  • the body 12 is equipped with usual member 23 connecting to the heating circuit thereto the boiler 1 is connected and it comprises a duct 24 connected to such member 23.
  • the above-mentioned walls delimitate an inner compartment of the expansion vessel 9 wherein a (not shown) usual membrane is placed.
  • the front wall 20 of the body 2 has at least a partly concave concavity 25, said wall 20 thus receding into the inner compartment of the box-like body 12 of the vessel 9 towards the rear wall 21 of the latter.
  • the wall 21 can be fully flat or slightly rounded or convex (as in figures), projecting towards the structure or casing 2 of the boiler.
  • the expansion vessel 9 is subject to a pressure variation from 0.5 to 2.5 bar, such vessel has to guarantee a resistance to size deformation during operation. Therefore, advantageously the front wall 20 is equipped with bosses or stiffening ribs 28 along the whole concave surface thereof.
  • the expansion vessel 9 has the front wall 20 equipped with two hollowed portions 25A, 25B wherein boiler components (the fan 6 and a gas valve 30 on the side thereof an electronic circuit controlling the boiler 31 is schematically shown) partially position. Also with such variant a width reduction of the boiler 1 is obtained.
