ABSTRACT:
A method and an apparatus are disclosed for drying and preheating coking coal particles of mixed sizes in a flight stream tube. A stream of hot gas in which different-size particle fractions are entrained, is advanced through the tube. At one or more locations it is split up into two flows, one containing the smaller fractions and the other containing the coarser fractions. The coarser fractions are slowed and readmitted into the flow having the smaller fractions, counter to the direction of advancement of this flow.
