Definitions

  • the present invention relates to a valve with automatic closure, capable of limiting the injection of combustion air under the hearth of a solid fuel boiler.
  • this arrangement does not allow the combustion air intake to be completely shut off when the fan is stopped, so that, as a result of natural draft, this air continues to penetrate under the hearth and to supply the flame, even reduced.
  • the invention relates to a valve mounted for rotation on an axis disposed in its upper part, which valve is lifted by the air current produced by the fan and falls back on the mouth intended for admission. combustion air by completely closing it when said fan is stopped.
  • a screw capable of being adjusted in position and thus constituting an end-of-travel stop capable of limiting the opening of the valve in order to prevent the latter from being excessively lifted by the current. air when the fan is running.
  • the invention is illustrated in the accompanying drawing, the single figure of which is an axial vertical section of the mouth. for injecting combustion air under the fireplace using a fan.
  • the assembly shown is mounted on a door 1 provided with a closing handle 2, said door being disposed in the lower part of the hearth of a boiler 3 intended for the production of hot water.
  • a closing handle 2 In the bottom of this door 1 is formed an opening 4 made below the grid 5 on which burns the solid fuel (wood or coal) which feeds the hearth.
  • the door In the axis of the opening 4 the door is integral with a duct 6 on the free end of which is mounted the fan 7 which supplies the hearth with combustion air.
  • a co-axial tube 8 cut in a bevel, suitable for being closed by a flap or valve 9 mounted for rotation on an axis 10, which is arranged at its upper part.
  • valve 9 remains raised to the position in broken lines, while when following the increase in the temperature of the water in the boiler said fan 7 stops, this valve falls back to the position shown in solid lines, thereby closing the duct 6.
  • the adjustment of the screw 12 makes it possible to determine the opening amplitude of the valve 9 depending on the combustion conditions you want to obtain in the fireplace.
  • the weight of the valve 9 must be determined so as to allow it to be lifted under the effect of the current of combustion air which moves in the direction of arrow 11, but this valve must not be too light so that the natural draft which intervenes when the fan 7 is stopped cannot cause its untimely lifting.
