Beschreibung
Zusammenfassung:	A fuel coal processing system is provided which consists of a centrifugal type pulverizer which consists of a pair of opposed multicup concentric ring rotors (5) and (6), a coal purifier (12) which consists of an annular ring nozzle surrounding the outer periphery of the pulverizer rotors and an optional fuel coal size classifier (13), all combined into one integral, cooperatively acting, fuel coal preparation device. Triboelectrostatic purification means may also be used alone or in conjunction with the aerodynamic means to more effectively handle different conditions and kinds of coal. L'invention se rapporte à un système de traitement de charbon combustible, composé d'un pulvérisateur de type centrifuge qui comprend une paire de rotors annulaires concentriques opposés (5) et (6) à plusieurs godets, d'un purificateur (12) de charbon qui comprend un ajutage annulaire entourant le pourtour externe des rotors pulvérisateurs, et, éventuellement, d'un classificateur granulométrique (13) de charbon, tous combinés en un seul dispositif de préparation de charbon solidaires et coopérants. Des éléments de purification tribo-électrostatiques peuvent également être utilisés, seuls ou conjointement avec des éléments aérodynamiques afin de traiter plus efficacement différents types de charbon dans différentes conditions.
