Abstract

L'invention concerne un dispositif pour brûler un combustible gazeux en formant le moins possible d'oxyde de l'azote. Ce brûleur comprend un tube, plusieurs ouvertures 36 de brûleur primaire disposées suivant une aire transversale par rapport à ce tube, des moyens pour amener dans ce tube le gaz combustible et l'air de combustion primaire aux ouvertures 36, et des moyens pour amener de l'air de combustion secondaire 64 autour dudit tube En amont des ouvertures 36, il y a des ouvertures 56 formant brûleur secondaire et où brulent à l'extérieur du tube, en amont du brûleur primaire et dans la zone d'écoulement, du combustible gazeux et de l'air primaire provenant de l'intérieur du tube. Le prémélangeur des produits de combustion du brûleur secondaire avec l'air secondaire permet de réduire la production des oxydes d'azote nocifs. Application : fours divers.
