Abstract

L'invention concerne un système de brûleur (20) comportant un corps de torsion conique ayant la forme d'un double cône (11), disposé de façon concentrique par rapport à l'axe de brûleur (21), renfermant un espace de torsion (17), et une lance à combustible centrale (12) située dans l'axe de brûleur, faisant saillie dans l'espace de torsion (17) depuis la pointe conique du corps de torsion (11). Le système selon l'invention comporte un premier étage (18) d'injection de combustible de prémélange dans lequel le combustible de prémélange est injecté radialement vers l'extérieur, dans l'espace de torsion (17), au moyen d'ouvertures d'injection disposées sur la lance à combustible (12), et un deuxième étage (14) d'injection de combustible de prémélange dans lequel le combustible de prémélange est injecté dans un flux d'air guidé au travers du double cône (11), au moyen d'ouvertures d'injection pratiquées dans le double cône (11). Selon l'invention, la pression gazeuse nécessaire dans le premier étage est réduite du fait que dans le premier étage (18), l'ensemble du combustible de prémélange est injecté dans l'espace de torsion (17) au moyen de deux ouvertures d'injection opposées (19) présentant un diamètre d'ouverture agrandi.
