Definitions

  • the present finding concerns a burner particularly suitable for stoves fired by pellets, woodchips, cereals and vegetable waste in general.
  • the fuel is contained in a collection space, arranged outside or directly inside the stove body, from where, through an Archimedean screw, it is taken to be gradually deposited in the burner.
  • the burner consists of a fuel collection tank, equipped with a perforated bottom through which comburent air enters into the combustion chamber.
  • the fuel collection tank is square or rectangular shaped and is equipped with vertical walls that define the brazier and have the task of containing the ashes.
  • the purpose of the present finding is that of making a burner that allows complete combustion to be obtained even using poor quality solid fuels.
  • the purpose of the finding is that of making a burner in which the through holes for the comburent air present on the base grid are never blocked.
  • a further purpose of the finding is that of making a self-cleaning burner, in which the ash and the other solid products of combustion are taken away from the brazier automatically.
  • Such purposes are obtained by foreseeing that a device acts on the plane of the brazier that continuously cleans the base grid, equipped with entry holes for the comburent air.
  • Such a device consists of a scraping blade arranged above and in contact with the grid, where said blade is moved with respect to said grid.
  • the tank that define3s the brazier is open on the two opposite side walls, which allows the lateral discharge of the ashes and of the other combustion residues from the brazier itself.
  • the ashes are moved onto the two sides of the tank and, gradually accumulating, they are pushed to the two open ends of the tank, until they spontaneously fall into the ash-collection drawer below.
  • the brazier wholly indicated with reference numeral 1, arranged inside the furnace 2, is supplied, through the Archimedean screw 3, with the fuel 4, contained in the accumulation space 5.
  • the brazier 1 comprises, in addition to the tank 6 for collecting and containing the fuel and ashes, also a blade 7, arranged substantially in contact with the perforated base 8 of the grid 9 of said brazier.
  • the blade 7 is arranged vertically with respect to the base 8 and is equipped with alternative angular motion or circular motion, obtained with per se known mechanisms, for which in each step corresponding to a swinging period or to a complete turn, the blade carries out a scraping action and therefore continuously cleans the perforated base itself, onto which the pieces of fuel fall and are deposited.
  • the perforated base 8 is slightly concave so as to ease the depositing of the pieces of fuel and to increase the contact surface between the scraping wire and said surface during the angular movement of said blade.
  • each alternative periodic angular movement of the blade 7 causes a sideways movement of the ashes, which gradually accumulate on the two sides of the tank. Said sides, being open, allow these ashes to fall freely, into a collector 10 below.
