Abstract:

Article Preview

This study is based on the image processing system by the authors, and performs microscope observations of the bubbles flow in dense-phase transport region of circulating fluidized beds. The research has tested and experimented on a cold scale-model circulating fluidized bed with a riser that has a 0.30mm × 0. 28mm cross-section and is 2.90 m tall with a video camera utilized to visualize the bubble structure through a transparent Plexiglas wall. The experiment was carried out at different particle sizes, different bed materials ,different heights and different height regions .The result analyzes the impact factor of the bubble size, shape and so on in the wall.
