Definitions

  • the present invention relates to a gas burner of the so-called "living flame” type, ie a gas burner whose flames bring to a certain degree of glowing logs or charcoal artificial, said gas burner being essentially constituted by a combustion chamber in which circulates the fuel (gas) / oxidizer (air) mixture primary), with a sheet at its upper part flat intended to receive an artificial fuel, said sheet having holes for the passage of said fuel / oxidizer mixture generally arranged at the limit of the aforementioned flat sheet.
  • the gas burner of the so-called "living flame” type is characterized in that the flat sheet cited in the preamble has at least one orifice, the aforementioned holes lying at the limit of one part of the outer perimeter of the aforementioned sheet and on the other hand of the interior perimeter of the aforementioned orifice.
  • the aforementioned holes have a diameter such that, taking into account of the pressure prevailing in the aforementioned chamber, of the primary air richness of the mixture fuel / oxidizer, the flashback phenomenon be made impossible.
  • Figure 1 is a plan view of the burner according to the invention.
  • Figure 2 is a view in perspective, in a schematic execution, showing the path that the fuel / oxidizer mixture can follow in the burner chamber.
  • the goal is to deflect the flames of these burners by making use of a draft secondary ascending, this is achieved within living flame burners which are basically consisting of a chamber 1 (fig. 2) in which circulates the fuel (gas) / oxidizer (air) mixture primary), and a flat top plate 2 (fig. 1) drilled with holes 3 - 3 'allowing the supply of flames.
  • the deflection of the flames must be done towards logs or fuel blocks artificial to carry at least locally to glowing artificial fuel placed on the flat sheet metal or in its vicinity.
  • the solid artificial fuel is disposed in such a way that at all operating modes, the yellow part of the flame - where the transient products of the extremely complex chemical reaction form fluffy aggregates of carbon (soot) - does not come into contact with a cold zone of the artificial fuel located between the zones carried incandescent, This avoids the deposition of soot which is burned at a higher level in the development of the flame.
  • This stratagem develops hygienic combustion with an almost perfect imitation of the ordinary combustion of a solid fuel.
  • the phenomenon sought is observed in a burner according to the invention.
  • the burner according to figures has a topological surface of gender greater than unity.
  • the flat sheet 2 of the burner according to these two figures presents, in the example represented, two orifices 4 which results in a significant elongation of the perimeter corresponding to the area in which are formed the holes 3 - 3 '(fig. 1).
  • the total scope is made up of the convex perimeter arising from the geometric shape flat sheet 1 plus the concave perimeter of one or several orifices 4. This gives a large power in a relatively flat surface burner scaled down. Due to the high concentration of flames on the surface of the flat sheet 1 of the burner a more appropriate (more aesthetic) arrangement of the artificial fuel is possible.
  • the burner design according to the invention allows a very flexible distribution of flames which gives full freedom to choose the passage necessarily clear of flames in the decor fireplace depending on the desired aesthetic.
  • any interior point i.e. any point at the interior of chamber 1 (fig. 2) can be reached by two different paths.
  • this point represented by the letter P can, from the venturi 5 through which the fuel (gas) / oxidizer mixture enters (primary air), be reached by one of the three paths designated by one of the references 6, 7 or 8.
  • the dynamic pressure of the mixture inside the burner is very homogenized easily at all flow rates, i.e. to all diets of power since the mixture is never found stuck or stuck in one or the other "dead end" there where the kinetic energy could turn into high static pressure.
  • the heterogeneity of the pressure of the mixture inside the burner would indeed create a heterogeneity of the ejection speeds of this mixture in direction of the flames, which would cause the detachment in excess air situation (blue flame) and a sooty stretch in a situation without excess air (yellow flame).
  • the burner shown in the figures has a hexagonal periphery. This perimeter could generally present n sides, or have a circular or oval outline.
