摘要
Device for transporting powder comprising a conveyer, which includes a lower channel in which a gas circulates, and an upper channel, designed for the circulation of powder and said gas, said lower channel and said upper channel being separated by a porous wall that said gas can pass through, the lower channel being supplied with gas at a pressure allowing the potential fluidization of said powder in said upper channel, said upper channel being provided in its upper part with transverse walls placed so that they delimit with the upper wall of said upper channel at least one upper zone in which a gas bubble under pressure is formed as a result of putting said air chute under potential fluidization pressure. At the level of at least one bubble so formed, the wall of the upper channel includes a means of removal for fluidization gas provided with a means of creating pressure drop, which creates a substantially constant pressure drop.
