<p>An apparatus for the distribution at a regulated rate of a fluidizable powdery material has a storage container (1), a porous wall and air conduit for fluidizing the powdery material and an orifice for discharging the fluidized powdery material. A casing (2) has two parts, an upper part (2A) connected to the storage container and to the orifice, and a lower part (2B) which is separated from the upper part (2A) by the porous fluidization wall (4). The upper part (2A) of the casing is connected at one of its ends (7A), to the storage container (1) by a column (3), at an upper part of its opposite end, to a balancing and degassing column (6) and, in its lower part (7B), to the outlet orifice (8) for the fluidized powdery material, which is disposed immediately above the level of the porous fluidization wall (4). The lower part (2B) is connected to an intake (5) for fluidization gas at a regulated pressure.</p> |
