Definitions

  • the present invention relates to a combustion stove.
  • Known combustion stoves have two air flows, namely one for the air which feeds the hearth and another for the air which, by circulating around this hearth, heats up and then spreads in the outdoor atmosphere.
  • the main object of the present invention is to produce a stove of the type described above, the combustion of which gives rise to a minimal quantity of unburnt particles and to a presence of carbon monoxide much lower than that of similar devices of known type, thus allowing to obtain, in addition to indisputable advantages on the environment and on human health, a very high combustion efficiency.
  • the stove according to the invention is defined in claim 1.
  • the device which generates hot air under pressure forms another original characteristic of the invention.
  • This device consists of a chamber placed in the upper part of the stove in direct contact with the exhaust fumes, which chamber will subsequently be referred to as the "economizer".
  • the chamber in question has, for the admission and the exit of the air, appropriately sized openings so that this air has time to heat up inside the aforementioned chamber and can, as a result of the increase of its volume, exit under a strong pressure thus favoring its complete mixing with the still unburnt gases which tend to rise for their evacuation.
  • the burnt gases are deflected by a profiled partition so as to force them to travel a longer trajectory, thereby causing better heat transfer to the heated air which is introduced in the atmosphere and in the room which generates the overpressure necessary for secondary combustion.
  • Another originality of the invention consists in ensuring that instead of being provided in the initial part of the exhaust duct, the flue adjustment flap is completely located inside the body of the stove and is adjusted from the outside using a lever.
  • the combustion stove comprises, in the manner known per se, a body 1 enclosing the combustion chamber 2 equipped a hearth 3 and a front door 4 made of ceramic glass, a series of air ducts which will be better specified below, and a smoke exhaust duct 5 provided with an adjustment flap 6.
  • two air flows namely that which is used to supply the combustion and that which, circulating in an intermediate space arranged outside the combustion chamber, allows the air to heat up and, by convection, to spread in the outside ambient atmosphere.
  • the air flow 7 which is intended to supply the main combustion is regulated by a key 8, while the air flow 9 freely penetrates into the lower part of the stove body and, through an intermediate space 10, rises by natural convection or under the effect of a fan 11 to exit upwards through a grid 12.
  • the essential characteristic of the invention resides in the provision of a third air flow intended to supply the combustion process.
  • the air flow 13 which enters the lower part of the stove through a duct 15, regulated by a flap 14, is introduced into a chamber 16, hereinafter called "economizer" and positioned in the upper part of the combustion chamber 2.
  • the air 17 contained in the economizer 16 heats up and, increasing in volume, leaves through openings 21 to generate a flow of pressurized air 18, against the current by with respect to the discharge fumes 19 which rise in the direction of the exhaust duct 5.
  • the inlet port 20 for the outside air must be wide while the evacuation of the air at high temperature must be carried out through small diameter openings 21 which act as blowing nozzles.
  • the ratio between the power of the hearth expressed in Kcal / h and the volume of the economizer expressed in cm3 must be 1 to 3; the ratio between the volume of the economizer, expressed in cm3, and the total area of the section of the blowing openings, expressed in cm2, must be from 1 to 220, and the ratio between the section of the inlet opening 20 and the total section of the blowing openings 21 must be from 1 to 3.
  • Another characteristic of the invention relates to the fact of providing a semi-circular wall 22 which lengthens the path of the discharge fumes 19 in the direction of the duct 5, as well as the insertion of the flap 6 for the adjustment of said fumes to the inside the body 1 of the stove, this shutter being controlled using an external operating handle 23.
  • the invention finally relates to the continuous cleaning of the inner face of the ceramic glass 4 by creating a chamber 24 provided above said glass.
  • This chamber 24 the inlet of which is regulated by means of a key 25, is heated by the combustion fumes, so that by increasing in volume, it exits through an orifice 26 to thus lick the internal face of the door 4 of ceramic glass.
