Abstract

La présente invention concerne un brûleur pilote pouvant s'utiliser à la fois comme brûleur pilote et comme tuyère à gaz dotée des fonctions pilotes de brûleur principal, l'absence de tige d'allumage permettant de réaliser ce brûleur pilote sous des dimensions réduites. Ce brûleur pilote (1) est constitué d'un cylindre extérieur conducteur (7) et d'un cylindre intérieur conducteur (9) se logeant dans le cylindre extérieur (7) dont il est électriquement isolé. Une haute tension appliquée entre le cylindre extérieur (7), servant d'électrode de terre, et le cylindre intérieur (9), servant d'électrode haute tension, permet de produire des étincelles dans les intervalles de décharge (39), à proximité des orifices d'éjection d'air (37). Cet agencement permet d'enflammer le mélange gazeux diffusé à proximité des orifices d'éjection (37), entretenant de ce fait des flammes pilotes (45) qui assurent la combustion du mélange gazeux diffusé plus en aval.
