Title (EN) LOW NOISE MODULAR BLADE BURNER
(FR) BRULEUR DE FAIBLE BRUIT A LAME MODULAIRE
Abstract: front page image
(EN)A burner (1), fed with a mixture of fuel and air, comprising a body (2) consisting of two half-shells having a plane of symmetry, inside said body a Venturi tube (3) being defined, provided with and inlet (4) into which said mixture of fuel and air is introduced, said Venturi tube (3) communicating upwardly with a distributing chamber (5) of said mixture of fuel and air, said distributing chamber (5) communicating upwardly with a burner head (8), closed upwardly by a diffuser (9), on which openings are made for the outflow and the subsequent combustion of said mixture of fuel and air, said distributing chamber (5) exhibits a first portion (6) and a second portion (7), said first portion (6), communicating with said Venturi tube, comprising at least a first stretch (6a; 6c; 6e) having a cross section of substantially constant width and at least a second stretch (6b; 6d) having cross section that increases progressively along a direction parallel to said plane of symmetry towards an end of said distributing chamber (5) faraway with respect to said Venturi tube (3), said second portion (7) having a section that increases progressively towards said burner head (8).
(FR)Selon cette invention, un brûleur (1), alimenté par un mélange combustible/air, comprend un corps (2) constitué de deux demi-coquilles ayant un plan de symétrie et à l'intérieur duquel est formé un tube Venturi (3). Ce corps de brûleur est pourvu d'un orifice d'admission (4) dans lequel est introduit le mélange combustible/air. Le tube Venturi (3) communique verticalement avec une chambre de distribution (5) du mélange combustible/air, cette chambre de distribution (5) communiquant elle-même verticalement avec la tête (8) du brûleur fermée en haut par un diffuseur (9) sur lequel sont formés des orifices pour la sortie et la combustion ultérieure du mélange combustible/air. La chambre de distribution (5) comporte une première partie (6) et une seconde partie (7), la première (6) communiquant avec le tube Venturi et comprenant au moins un premier allongement (6a ; 6c ; 6e) dont la largeur de la section transversale est constante, et au moins un second allongement (6d ; 6d) dont la section transversale augmente progressivement le long d'une direction parallèle au plan de symétrie allant vers une extrémité de la chambre de distribution (5) se trouvant loin du tube Venturi (3), la seconde partie (7) ayant une section qui augmente progressivement vers la tête (8) du brûleur.
