In this paper it is shown that the gas #ow pattern in the dense bottom-bed of circulating #uidized beds, operated with Geldart-B type of solids, exhibits three di!erent types of dynamic behavior, dependent on the width of the riser and on the aspect ratio of the dense bottom-bed. These types of dyna
