Definitions

  • the present invention relates to a heater appliance having a so-called “atmospheric” burner, that is a burner in which the oxygen for supporting combustion of the fuel supplied to the burner is obtained by drawing atmospheric air into the appliance.
  • atmospheric burner When used hereinafter the term “atmospheric burner” will be understood to relate to a burner as defined hereinabove.
  • heating appliances having one or more atmospheric burners usually have a side or lower face of the combustion chamber open for the purpose of allowing free entry of air necessary for supporting complete combustion of the fuel in the appliance.
  • the present invention seeks therefore to at least reduce the above mentioned disadvantages by providing a heating appliance with an atmospheric burner having a significantly improved thermal efficiency obtained without the necessity of substantial or complex modifications of the burner itself.
  • a heating appliance having an atmospheric burner, comprising a heater body defining a combustion chamber within its interior, in which at least one atmospheric burner can be located, characterised by the fact that the bottom wall of this combustion chamber is constituted by a pair of panel elements spaced from one another and provided with apertures for the introduction of air to support combustion of fuel by the burner.
  • An advantage of the present invention is that heat losses from the heater appliance due to radiation through an air inlet opening during operation of the burner are totally eliminated, and losses by convection attributable to the chimney effect which takes place in heater appliances at times when the burner is not in operation are drastically reduced.
  • Another advantage of the heating appliance of the present invention lies in the fact that the effective thermal efficiency of the appliance is significantly improved, thus contributing to a significant reduction in the running costs. Further, a heating appliance formed in accordance with the principle of the present invention is able to offer the widest guarantee of reliability and safety in use.
  • the heating appliance which is generally indicated with the reference numeral 1, comprises a heater body 2 which can be made in any shape or configuration which is considered suitable.
  • the heater body 2 defines, internally, a combustion chamber generally indicated with the reference numeral 3, within which are located burners 4, preferably gas burners, of the so-called atmospheric type.
  • the heating appliance of the present invention is particularly characterised by the fact that the lower part of the combustion chamber, that is to say the side which in a conventional heater is left open, is provided with a first panel element 5 and a second panel element 6, which both lie in substantially horizontal planes and which are spaced from one another.
  • the panel elements 5 and 6 are provided with apertures which allow the introduction into the combustion chamber of secondary air, necessary for the completion of the combustion of the fuel burnt by the burner.
  • the utilisation of the panel elements 5 and 6 offers the possibility of obviating the heat dissipation phenom- on which occurred in prior art heaters, without reducing the heating capacity of the apparatus.
  • the panel elements 5 and 6 are advantageously made of sheet metal or possibly any other material able to resist the high temperatures experienced in operation of the burner.
  • the first panel element 5 is flat with two opposite edges being provided with transverse flanges 9 facing downwardly and resting on the second panel element, which is also flat and has two upwardly directed flanges 10,11 on the edges correspondent to those of the upper panel 5.
  • the flange 11 is larger than the flange 10 and has recesses or notches in its free edge to receive the burner 4.
  • the first panel element 5 is provided with through-slots 7, whilst the second panel element is provided with through- holes 8, which constitute the said apertures.
  • the conformation of the apertures is not, per se, binding, in that it is possible to adopt any conformation considered suitable.
  • An advantageous criterion to follow is that, given the disposition of the apertures on the first panel element 5, the second panel element 6 is provided with apertures in such a way that the apertures themselves are not in mutual alignment, so as to eliminate or at least reduce to the minimum the chimney effect, which occurs when the burner is not in operation.
  • the apertures which, as has been said, may be constituted by slots or holes, are disposed and dimensioned in such a way as to allow only the quantity of combustion air necessary for complete combustion of the gas to be drawn into the appliance.
  • the arrangement of the various apertures on the panel elements 5 and 6 in such a way that they are not in alignment offers the possibility of creating a significant hydraulic resistance so that, when the burner is not operating,the chimney effect is substantially nullified.
  • This arrangement also allows the dispersion of heat downwardly of the combustion chamber due to radiation during operation of the burner to be eliminated, and the heat, which is transmitted to the panel elements by radiation during operation of the burners, is advantageously recovered by conduction to the air which is drawn through the apertures in the panels into the combustion chamber during the operation of the burner.
  • the materials used may be any suitable according to requirements.
