Abstract

Eine Wirbelschicht-Trockneranordnung zur Trocknung von Kohle, enthaltend einen Behälter (1); eine Heizungsanordnung (22) mit einer Vielzahl von parallelen Heizrohren oder -platten; und einen Düsenboden (28) mit einer Vielzahl von Düsen zur Erzeugung einer Wirbelschicht; ist dadurch gekennzeichnet, dass der aus verschiedenen Düsen des Düsenbodens (28) austretende Fluidstrom, insbesondere die Fluidgeschwindigkeit unterschiedlich ist. Es können Zonen vorgesehen sein, bei denen die Zonen wenigstens eine Einmischzone im Randbereich der Trockneranordnung und eine Trocknungszone im mittleren Bereich der Trockneranordnung umfassen. Dabei ist unter jedem Kohleeinfallschacht (2) eine Einmischzone vorgesehen.
