Abstract
Cette invention concerne un brûleur de combustible solide, qui, tout en rendant la capacité supérieure à celle de l'état antérieur de la technique, peut supprimer un accroissement de région non enflammée et peut ainsi réaliser la prévention d'une augmentation de la concentration en NOx dans un gaz de combustion et la prévention d'une diminution du rendement de combustion, et un équipement de combustion et une chaudière comprenant le brûleur. Le brûleur comprend une buse (12) d'alimentation en fluide contenant du combustible alimentant un fluide contenant du combustible, à partir d'une partie de connexion dans un passage (10) d'écoulement de transfert de fluide pour transférer un fluide contenant du combustible comprenant un combustible et un milieu pour le transfert du combustible, vers une partie de sortie disposée sur la paroi d'un four (4). La buse (12) d'alimentation en fluide contenant du combustible, dans sa section transversale perpendiculaire à la direction de l'écoulement du fluide, est de forme rectangulaire, elliptique ou approximativement elliptique ayant des parties d'axe majeure et mineure à partir d'une partie de connexion (10a) dans le passage (10) d'écoulement de transfert de fluide vers la partie de sortie disposée sur la surface de paroi du four (4). En outre, l'aire d'une section transversale perpendiculaire à la direction de l'écoulement du fluide est progressivement augmentée à partir de la partie de connexion dans le passage (10) d'écoulement de transfert de fluide vers la partie de sortie. Plusieurs buses (15) d'alimentation en air pour fournir de l'air de combustion sont disposées sur la partie périphérique de la buse (12).
