ABSTRACT:
An apparatus having a closed channel or container for transporting and/or distributing fluidizable material includes an air- or gas-permeable wall arranged in the channel and forming a partition between an upper pathway for the fluidizable material and a lower flue to which is fed fluidizing gas from a gas source via a tube. An inlet is provided for feeding fluidizable material to the channel. The apparatus also includes one or more outlets for continual or intermittent run off of material from the channel, and a tube for ventilating the channel. The channel is equipped at its inlet with pipe stub extending into the upper pathway. An area defined under the pipe stub is inactive or is equipped with a separately arranged fluidizing wall with a separate gas feed.
