| Abstract: | In a three phase circulating fluidized bed,under a wide range operation conditions,the glass beads was used as solid phase,the water was used as liquid phase,the air was used as gas phase.The effects of superficial gas velocity,superficial liquid velocity and particle density on gas holdup were studied.The experimental results also show that the gas velocity had an effect on bed expansion height and air bubble diameter. |
