Abstract

PURPOSE:To prevent leakage of fluidizing medium into an air chamber by arranging a blind plate in an area about a jet air injection part in a furnace designed to inject a jet air from the center of a funnel-shaped porous plate while a spiral air flow is injected through an air hole on the side of the porous plate. CONSTITUTION:A jet air is injected from a jet air injection part 4a provided at the center of a funnel-shaped porous plate 1 while a spiral air flow is injected from tangential air holes 2 opened on the side of the porous plate 1 whereby a fluidizing meidum (not illustrated) on the porous plate 1 is fluidized to form a fluidized bed. In a furnace of such a type, a blind plate without air hole is arranged within a fixed diameter (a) centered on the jet air injection part 4a to prevent leakage of the fluidizing medium from the port involved. Here, the diameter (a) is 400-900mm., preferablly 600-800mm..
