A gas dispersing device to be employed in a fluidized bed preliminary reducing furnace is constructed of a plurality of rotatable round bars arranged in multiple stages so as to form a grate. The gas dispersing device includes a rotating mechanism for rotating each bar. Deformation of the bars due to temperature change is avoided thereby to extend a life of the dispersing device. Furthermore, blinding of the dispersing device can be prevented thereby to effectuate a stable operation of a fluidized bed. Accordingly, productivity in the fluidized bed reducing furnace is improved, and labour saving is realized.
