This report describes the flow patterns and flow characteristics of a gas and solid mixed phase flow (air and glass bead particles) in the riser of a CFB (circulating fluidized bed). Flow patterns strongly depend on the inlet air flow rate and the relative flow rate of circulating particles. Therefore these fluidization patterns were clarified three groups, which belong to three regions : slugging or turbulent, fast and dilute. These flow patterns have differing characteristics from each other. Futhermore, in the regions of fast and dilute fluidization, clusters of fluidizing particles were observed.
