Definitions

  • Known pellet-fed combustion devices for room heating include, adjacent to the burner, a vessel of small dimensions (30, 50 kg of pellets) connected to the burner via a shutter which, acting automatically, feeds the burner region with the pellet quantity necessary for combustion.
  • An object of the present invention is to provide a system for feeding pellets to a combustion device which overcomes the said drawbacks of the known art.
  • a further object of the present invention is to provide a system which provides a pellet-fed combustion device with much longer self-sufficiency than traditional systems.
  • Another object of the present invention is to provide a system which improves the quality of the environment in which the combustion device is installed, by eliminating a possible dust source.
  • the container comprises a large-dimension container 2 able to house indicatively a pellet quantity of about 250 kg or more.
  • the container presents a parallelepiped portion 3 supported by uprights resting on the ground.
  • the parallelepiped portion is sealedly closed upperly by a removable cover to give access to the container interior for its filling with pellets.
  • the lower part of the parallelepiped portion 3 is welded to a conveyor 4 provided with an inspection window 5 and terminating with a flange 6.
  • the flange is bolted to a hopper 7, at the inlet of which a screw 8 is disposed, rotated by a gearmotor 9.
  • the screw acts as a shutoff and control means for the flow of pellets delivered by the container 3.
  • a transfer unit 10 is fixed via a coupling frame 10A to a side face of the hopper 9 in correspondence with an aperture, to connect the hopper interior to a tubular element 11.
  • the transfer unit presents, welded to the frame, a convergent part terminating in a portion 13 which embraces the tubular element 11.
  • a lateral window 14 facing the interior of the transfer unit is provided in the tubular element 11, the convergent portion 12 of the transfer unit presenting an inspection window 15.
  • a convergent nozzle 16 is fixed in the tubular element to partially overlap the window 14.
  • the cavity of this nozzle presents a first frusto-conical portion 16A to which, in the final part of the cavity, an asymmetric portion is connected which in its upper part continues the frusto-conical profile as a straight line, whereas in its lower part it presents a curved connection 16B with a rapid reduction of its passage cross-section.
  • a connector tube 19 is present, connected to the delivery of a pneumatic feed means comprising a fan enclosed in a casing 18.
  • the casing and fan are positioned in use below the container 2, to reduce the overall size of the system.
  • a flame trap device 20 Directly downstream of the hopper, below the container 2, there is a flame trap device 20.
  • This flame trap device prevents flame returning to the container if conduits are obstructed. It comprises a chamber with an inlet 21 and an outlet 22, when in use the inlet 21 being connected to the outlet 11 A of the tubular element 11.
  • the chamber of said device is defined by perimetral walls 23 and an inclined wall 23A on which a door 24, freely openable towards the chamber interior, is hinged along an axis A. The weight of the door maintains it closed, abutting against that face of the wall 23A inside the chamber. Any vacuum created in said chamber causes the door 24 to automatically open, to again close automatically when the pressure inside the chamber is restored.
  • the device 20 also presents a filter mesh (not shown) facing the aperture 21.
  • the outlet 22 of the device 20 is connected via an antistatic flexible conduit 30 to a vessel 31 incorporated into or positioned next to a pellet combustion device or burner 32.
  • the container 2 the pneumatic feed means 18 and the safety device 20 are located in a room remote from that in which the combustion device is located.
  • the combustion device 32 is a stove.
  • the control logic for the vessel 31 and for the feed of pellets withdrawn from said vessel is totally conventional.
  • the vessel 31 presents a pellet loading port 33 connected to said conduit 30.
  • the vessel 31 also presents an air discharge port 34 connected via a return conduit 35 to the suction side of said fan 18.
  • the loading port and the discharge port are integrated into a cover for the vessel 31.
  • the vessel 31 and the container 2 are sealed, and together with the aforedescribed components and the flexible conduits 30, 35 form a closed circuit through which pressurized air circulates when the fan 18 is active.
  • the control centre 40 activates the fan 18 which pressurizes the circuit.
  • the pellets which have passed from the remote container into the hopper are thrust by the air flow generated by the fan into the vessel 31, to restore its adjustable preset level.
