Abstract

La génération d'une scorification est supprimée dans un brûleur à charbon pulvérisé. Un corps de buse (6) s'ouvrant vers un four (1), transportant du charbon pulvérisé et l'injectant conjointement avec de l'air primaire (14), devenant finalement de l'air de combustion, a une buse de tube externe (8) et une buse de tube interne (9) disposée dans la buse de tube externe (8) de façon concentrique à celle-ci. Un espace de conduction de combustible (10) est formé entre la buse de tube externe (8) et la buse de tube interne (9), et au moins l'une de la buse de tube externe (8) et de la buse de tube interne (9) est dotée d'une plaque de redressement (29) se projetant dans l'espace de conduction de combustible (10) et s'étendant dans la direction axiale du corps de buse. L'air de combustion (air primaire (14)) contenant du charbon pulvérisé est éjecté à travers l'espace de conduction de combustible (10).
