Abstract

Brûleur de combustible à faible combustibilité pouvant assurer une bonne performance d'allumage et une stabilité de combustion, même si un débit de gaz est modifié avec un changement de la charge de chaudière ou similaire. Un brûleur de combustible à faible combustibilité sépare un combustible à faible combustibilité pulvérisé fourni avec de l'air à l'aide d'un séparateur, distribuant le combustible séparé à un injecteur de portion riche et à un injecteur de portion pauvre prévus dans la chaudière, et brûlant le combustible, dans lequel une partie de commande variable telle qu'un cour ou une vanne d'ajustement/de blocage d'écoulement est prévu dans au moins l'une d'une conduite de gaz à concentration particulaire élevée, s'étendant d'un côté aval du séparateur et communiquant avec l'injecteur de portion riche, et d'une conduite de gaz à faible concentration particulaire s'étendant du côté aval du séparateur et communiquant avec l'injecteur de portion maigre.
