Title
(EN) A BURNER NOZZLE
(FR) BUSE DE BRÛLEUR
Abstract
(EN) Invention relates to a burner nozzle (10) for atomizing liquid fuel with assistance of compressed gas, comprising a first outlet (16) for compressed gas, having a center axis (18) and a second outlet (20) for liquid fuel. The second outlet (20) is arranged rotationally symmetrically around the first outlet (16) in respect to the center axis (18), the first outlet (16) comprises an outwardly extending conical portion (22), and the burner nozzle (10) comprises a gas dispersing element (24) which is arranged to the center axis (18) at a distance from and coaxially with the first outlet (16) in the direction away from the first outlet (16).
(FR) La présente invention concerne une buse de brûleur (10) pour pulvériser un combustible liquide à l'aide d'un gaz comprimé, comprenant une première sortie (16) pour le gaz comprimé, ayant un axe central (18) et une seconde sortie (20) pour le carburant liquide. La seconde sortie (20) est disposée de manière symétrique en rotation autour de la première sortie (16) par rapport à l'axe central (18), la première sortie (16) comprend une partie conique s'étendant vers l'extérieur (22), et la buse de brûleur (10) comprend un élément de dispersion de gaz (24) qui est disposé sur l'axe central (18) à une certaine distance de la première sortie (16) et coaxialement à celle-ci dans la direction opposée à la première sortie (16).
