To prevent the stopping of a furnace by the growth of aggregate from fluid medium by arranging equipment classifying fluid medium between a fluidized bed furnace and fluid medium storing equipment, or providing the equipment in fluid medium storing equipment.
The quantity of the fluid medium equivalent to the fluid medium inside the furnace is transported from an evacuating pipe line of the fluid medium at the bottom part of a fluidized bed furnace through a transport pipe line 94 to storing equipment 95 provided with the equipment classifying the fluid medium. An inclined screen 51 is arranged to the inside of the storing equipment 95 and the transported fluid medium inside the storing equipment 95 is flowed down on the inclined screen 51. Smaller particles in the fluid medium are dropped to the bottom part of a container 95A though the meshes of the inclined screen 51 while the particles are flowed down. The particles of the size that cannot pass the meshes of the inclined screen 51 flow down on the inclined screen 51 without dropping and are taken out to the outside of the circulating path of the fluid medium through the discharging pipe line 97 of the coarse particles.
