Definitions

  • the present invention concerns a solid fuel wall-mounted boiler, in particular a biomass wall-mounted boiler (for example a pellet boiler), able to be used for heating rooms, be they for civil or industrial use, as well as for producing sanitary hot water.
  • a biomass wall-mounted boiler for example a pellet boiler
  • the ignition of the combustion is obtained by feeding current to an electric resistance arranged behind a combustion chamber in which the biomass (pellets) is loaded.
  • the electric resistance made incandescent by Joule effect, heats the air at room temperature fed from outside into the combustion chamber. The flow of air thus heated hits the biomass contained in the combustion chamber and sets it alight.
  • Such a known ignition system on the one hand requires long ignition times, which vary on average between 15 and 20 minutes and are therefore incompatible with use of the boiler to produce sanitary hot water, and on the other hand involves high electrical energy consumption, since the power involved is in the order of 200 ⁇ 300 W.
  • a further drawback of current solid fuel boilers, and in particular of biomass (pellet) boilers, able to be used both for heating rooms and for producing sanitary hot water, is represented by the considerable overall sizes and therefore by the fact that it is impossible to position the boiler in common boiler spaces provided in civil dwellings, in particular in the case of boiler spaces located inside apartments and/or relative balconies. Therefore, it is not possible to consider, in an apartment already set up for the installation of a gas boiler or already equipped with a gas boiler for heating and for producing sanitary hot water, replacing the gas boiler with a solid fuel boiler, in particular a biomass (pellet) boiler, currently produced. Indeed, it would be necessary either to provide a special boiler room able to receive the new boiler or to arrange the new boiler on the floor inside the apartment itself. Both of these solutions are, however, clearly not very convenient.
  • biomass boilers such as pellet boilers
  • a wall-mounted pellet boiler according to a preferred embodiment of the present invention is wholly indicated 10 and basically comprises a frame structure 12, a tank unit 14 supported by the bottom part of the frame structure 12 and a boiler body 16 supported in the top part of the frame structure 12.
  • the frame structure 12 can be observed as a whole in figure 2 and, limited to just the top part, in figures 4 and 5 and basically comprises four vertical uprights 18 and a plurality of horizontal cross members 20 that interconnect the vertical uprights 18.
  • the frame structure 12 is divided into two parts, namely a bottom part that supports the tank unit 14 and a top part that supports the boiler body 16.
  • a constructive choice is not in any way necessary, as the frame structure can also be made in a single piece.
  • what is important for the purposes of the present invention is the arrangement of the tank unit 14 below the boiler body 16.
  • the boiler and in particular the boiler body 16 to be wall-mounted, or suspended, for example in a pre-existing boiler space, to replace a gas boiler with a pellet boiler.
  • the arrangement of the tank unit 14 at the bottom makes it easier to load the solid fuel (in the present case pellets) and also makes it possible to avoid risks of the solid fuel contained in the relative tank from catching fire.
  • making the frame structure 12 in two distinct parts, that is a bottom part and a top part, respectively, allows greater freedom in mounting the tank unit 14 and the boiler body 16.
  • the tank unit 14 is arranged in the bottom part of the boiler, as mentioned above, and basically comprises a fuel tank 22, in which the solid fuel (in the present case pellets) intended to be fed to the burner of the boiler is contained, an ash container 24, in which the combustion residue (ash) coming from the burner of the boiler is collected, and a tank 26 for sanitary hot water.
  • the ash container 24 is extremely small in size, since the high efficiency of the combustion that can be obtained with the boiler according to the invention ensures that the amount of ash produced is much less than known pellet boilers. Therefore, it is possible to minimise the size of the ash container 24 without increasing the frequency with which the user of the boiler has to take care of emptying it.
  • the tank 26 for hot water is advantageously received in the tank unit 14 arranged below the boiler body 16, but might also be arranged in any other position than the fuel tank 22, if necessary even above the boiler body 16.
  • the tank 26 for sanitary hot water it is preferable to arrange the tank 26 for sanitary hot water inside the tank unit 14, as this contributes to containing the overall sizes of the boiler.
  • the boiler 10 basically includes the following modules:
  • the burner module basically comprises a crucible 30 ( figure 11 ) and an ignition device wholly indicated 32 ( figure 9 ).
  • the crucible 30 has a bottom wall 34 with a plurality of holes 36 for the comburent air that enters into the boiler body 16 through one or more openings 28 ( figures 5 to 7 ) provided in a side wall thereof.
  • the ignition device 32 comprises:
  • the ignition of the pellet is obtained by exploiting the heating effect of the rod by induction and the ignition effect of the pellet by direct contact with the rod.
  • the ignition device according to the invention much shorter ignition times, in the order of 2 minutes at most, and much lower consumption, in the order of a few Watts, are obtained.
  • the performance of the boiler in terms of response speed in this way becomes comparable to that of a common methane boiler, which is particularly important above all in view of the use of the boiler for producing sanitary hot water.
  • the ignition device 32 has an associated temperature sensor T0 that by measuring the resistance in the conductors of the secondary of the transformer 38 is able to detect the temperature in the rod 40, and therefore the combustion temperature. It is thus possible to control the combustion temperature in real time and in an extremely simple manner.
  • the ignition device 32 described above is clearly able to be used in a boiler operating with any other different type of solid fuel.
  • the heating chamber module is arranged in a top space 44 of the boiler body 16 defined at the bottom by a horizontal plate 46 having a central opening in which the crucible 30 is inserted ( figure 11 ).
  • the heating chamber module basically comprises a heat exchanger 48 having the function of transferring the heat of the fumes produced by the combustion of the pellet to the water of the heating circuit associated with the boiler.
  • the heat exchanger 48 includes a body 50 that almost completely envelops the area where the combustion heat is generated and that contains the water to be heated.
  • the body 50 includes a first front vertical portion 50a that closes the top half of the space 44 at the front, a second top horizontal portion 50b that closes the space 44 at the top and a third rear vertical portion 50c that closes the space 44 at the back.
  • a plurality of fins 52 are provided, which have the function of increasing the heat exchange surface between the fumes produced by the combustion and the water contained in the body of the exchanger.
  • the heat exchanger 48 also includes a separating plate 54 made from refractive material that separates the fins 52 from the area in which the combustion takes place and has the function of conveying the fumes against the surface of the body 50 equipped with the fins 52.
  • fins 52 are depicted just on the front face of the portion 50c of the body 50 of the heat exchanger 48, fins may also be provided on the faces of the other two portions 50a and 50b of the body 50 licked by the fumes, in other words on the rear face of the portion 50a and on the bottom face of the portion 50b.
  • further separating plates made from refractive material are advantageously provided, which are suitable for conveying the fumes against the further finned faces of the body of the heat exchanger.
  • the fume extraction module basically includes:
  • the motor fan 60 has an associated angular velocity sensor H (schematically indicated in figure 15 ), for example made as a Hall effect sensor, which provides an angular velocity signal to an electronic control unit ECU ( figure 15 ) that oversees the operation of the boiler, for feedback control of the motor fan.
  • H angular velocity sensor
  • ECU electronice control unit
  • the ash discharging module basically includes a roller 68 suitable for fragmenting the residue of the combustion of the pellet (ash) that accumulates in the crucible 30 and conveying it towards the ash container 24 through a chute 70 and a vertical tube 72, as well as an electric motor 74 (schematically illustrated in figures 1 , 2 and 5 ) suitable for setting the roller 68 in rotation.
  • a roller 68 suitable for fragmenting the residue of the combustion of the pellet (ash) that accumulates in the crucible 30 and conveying it towards the ash container 24 through a chute 70 and a vertical tube 72, as well as an electric motor 74 (schematically illustrated in figures 1 , 2 and 5 ) suitable for setting the roller 68 in rotation.
  • the roller 68 comprises a cylindrical outer shell 76, preferably made from stainless steel, having a plurality of through openings or holes 78, which are made in the present case as perforated protuberances projecting in the radially outward direction so as to make a grated surface, and an auger or screw (not shown) arranged inside the shell 76.
  • Both the shell 76 and the auger are set in rotation by the electric motor 74.
  • the shell 76 thanks to the grated outer surface cooperating with the perforated bottom wall 34 of the crucible 30, has the function of fragmenting the combustion of the pellet, whereas the auger has the function of axially discharging such residue from the shell 76, conveying it towards the chute 70.
  • the electric motor 74 is automatically controlled by the electronic control unit ECU.
  • the roller 168 comprises a cylindrical outer shell 176, preferably made from stainless steel, having a plurality of through openings or slots 178, so as to allow the combustion residue (ash) to pass through, each of the through openings or slots extending along a direction inclined with respect to the axis of the shell (i.e. to the axis of rotation of the roller).
