Definitions

  • the subject of the present invention is a gas burner with atmospheric combustion, with a mixture of the so-called hyperstechiometric type, of substantially tubular shape, in which the mixture exits through a series of slots made in the wall of the burner body, which slots are arranged according to one or more rows which extend parallel to the axis thereof.
  • the burner in question is more particularly able to provide, with regard to the NO X emission, results comparable to conventional burners whose wall is cooled using water from the boiler (cf. burners described in Italian patents Nos. 1,191,596 and 1,214,314, both in the name of this Applicant).
  • the object of the present invention is to produce a gas burner of the above-mentioned type which is capable, under normal operating conditions, of maintaining its surface temperature at a level capable of allowing modulation of the flame or, better still, a lower than normal gas supply pressure, without the need for water cooling as mentioned above.
  • the burner according to the invention is defined in claim 1.
  • the fixed objective is obtained by making the inner face of the burner comprise at least one rib made of a heat conducting material, which rib extends parallel to the axis of the burner.
  • the invention relates to particular embodiments capable of making the device particularly useful and functional.
  • Figures 1, 2 and 3 are respectively a plan view from above, a longitudinal section and an end view with cutaway, showing the device according to the invention in a particular embodiment.
  • the invention relates to a burner 1 of substantially tubular shape.
  • the combustible gas enters this burner through a nozzle 2 and mixes with the combustion air in a Venturi 3 disposed in the interior space of said burner, below the upper wall 1 'thereof; in this upper wall 1 'is formed a series of slots or slots 5 arranged side-by-side in one or more rows which extend parallel to the axis of the burner.
  • the mixture is brought to the slots 5 at which combustion takes place, after passing through a distributor 4 provided at the outlet of the Venturi 3, in the manner known per se.
  • the fundamental characteristic of the device according to the invention resides in the fact that the interior space of the burner contains, at the level of the zones defined by the slots 5, at least one rib 6 made of a material which conducts heat, this rib s' extending parallel to the axis of the burner. Several ribs 6 are preferably provided.
  • these ribs 6 are located in the intermediate space existing between two contiguous rows of slots, the slots of these rows being aligned perpendicular to the axis of the burner.
