Abstract

The present invention is to provide a method for drying a wet raw material such as a coal to be charged into a coke furnace in a fluidized bed dryer, through forming a fluidized bed on a gas dispersing plate positioning above wind boxes, wherein the wet raw material having fallen into the wind boxes is recovered, and then, is transported to a charging chute or the like via a second by-pass pipe, to thereby again charge it into the fluidized bed. The above method allows the drying of a wet raw material having fallen into the wind boxes of the fluidized bed dryer with reliability, which results in the achievement of a target water content of a treated material with reliability.
