Definitions

  • the present application relates to a heating apparatus comprising at least one air injection ramp.
  • the document EP-867662 describes a double-hearth fireplace which has a combustion chamber comprising an upper opening closed by two removable plates. According to this embodiment, the first hearth is positioned on the removable plates and the second hearth is positioned in the combustion chamber, below the removable plates.
  • the air required for the combustion of the fuel enters the combustion chamber through the upper opening, which is not completely obstructed by the two removable plates.
  • the removable plates and the perimeter of the upper opening are configured so that there is a clearance between the two removable plates and between the removable plates and the perimeter of the opening.
  • a first casing is provided around at least a portion of the side walls of the combustion chamber.
  • the space between the side walls and the first casing is intended for the circulation of combustion products from the combustion chamber to an exhaust duct.
  • the right and left side walls of the combustion chamber are spaced from the front side wall so as to create two lateral exhaust openings.
  • the combustion products are evacuated from the combustion chamber via these lateral exhaust openings, then they travel to the rear of the right and left side walls of the combustion chamber to reach the exhaust duct positioned at the rear of the rear side wall of the combustion chamber.
  • a second envelope is provided around the first envelope, a space between the first and second envelopes being provided for the circulation of air from the room to be heated.
  • the rear wall of the combustion chamber includes a direct discharge opening that directly connects the combustion chamber and the discharge duct. Depending on the spacing between the removable plates, a re-ignition of the fumes is obtained at the direct discharge opening, which reduces the amount of unburned material and increases the thermal efficiency of the combustion chamber.
  • the document FR-2947037 proposes a solution to further reduce the quantity of unburned material and increase thermal efficiency.
  • two air introduction ducts are positioned at each of the side exhaust openings.
  • Each duct is positioned vertically and includes a plurality of orifices.
  • These air introduction ducts positioned on the combustion product evacuation path, make it possible to relight a greater quantity of combustion products and therefore reduce the quantity of unburned material and increase thermal efficiency.

  • the air intended for the main combustion is supplied from the bottom of the combustion chamber.
  • the stove also includes an air injection ramp to initiate post-combustion when the flap is in the open position.
  • the air supply for the main combustion is achieved via openings provided at the level of the lower wall. This configuration is not optimal because the openings can be partially or completely blocked by the ash generated by the combustion.
  • US4249509 A discloses a heating apparatus comprising a primary air injection ramp in the lower part of the combustion chamber, and a second chamber for post-combustion.
  • the present invention aims to remedy all or part of the drawbacks of the prior art by proposing a solution which improves combustion.
