PURPOSE: To make it possible to receive and exhaust a particulate material constantly at a high temp. zone as well as to improve a fluidized condition in the vicinity of a particulate material receiving port by providing an auxiliary fluidizing fluid introducing chamber immediately below the particulate material receiving port.
CONSTITUTION: A fluidizing chamber 1 is constituted by providing the particulate material receiving port 3 to a container like main body 2 as well as by providing an exhaust port 4 to a position higher than the particulate material receiving port 3. To a lower part of the fluidizing chamber 1, a main fluidizing fluid introducing chamber 6 and the auxiliary fluidizing fluid introducing chamber 7 are provided by interposing a porous rectifying plate 5 in a partitioned manner and, to the respective introducing chambers 6, 7, introducing ports 8, 9 for guiding a fluid blown up into the fluidizing chamber 1 are connected. The axuiliary fluidizing fluid introducing chamber 7 is provided immediately below the particulate material receiving port 3 and guides the fluid in the vicinity of the particulate material receiving port 3 to activate fluidity in this section and, moreover, the fluid from the main introducing chamber 6 fluidizes the whole particulate material in the fluidizing chamber 1 to facilitate exhaustion.
