This paper described the applied limitation of this spatial filtering method(SFM) for measuring the particle velocity which was affected by the conditions for the criterion of particle packing particle concentration. As the typical approach on the image processing of the image data SFM was used for estimating of the particle velocity in a circulating fluidized bed. SFM was introduced as the optical velocimetry for one of untouched measurement tools. For the sampling of image pictures, it was taken by the high speed video camera(1000/500fps) for a simple cold model of CFB. As the results, the clear and local particle velocity distributions for the various superficial gas velocity (ranging from 2.7m/s to 3.7m/s) and the various circulating particle flow rate (ranging from 2.9 kg/m<SUP>2</SUP> to 13.0kg/m<SUP>2</SUP> ) were obtained.
