A fluidized bed, comprising: a vessel, a cyclone cooperating with said vessel for separating out particulate material and returning the material to the fluidized bed, a leg extending down from said cyclone for returning the particulate material to the fluidized bed; an eductor at a lower portion of said leg, said eductor having an exit end; and a pressurized gas line within the leg having an opening before the exit end of said eductor so as to blow gas through said eductor and out of said leg, wherein said pressurized gas flowing out of said eductor creates a gas stream near the bottom of said vessel which fluidizes the bed and induces a downward air flow in said leg to help pull particulate matter down said leg.
