• 中文摘要： 本研究藉由床壓力擾動, 探討穿孔板分佈器設計對氣固流體化床於淺床時流體化品質之效應。結果發現, 壓力擾動與氣體流經孔口進入床內時, 形成噴氣或氣泡的分佈型態有關。固定一開孔比大於2.0%的穿孔板, 孔徑愈大能使噴氣型態愈穩定, 並得到較佳的流體化品質; 反之, 採用小孔徑的設計, 對淺床的操作較佳。
• 英文摘要： The effect of a perforated-plate distributor design on fluidization quality in terms of pressure fluctuations was investigated in shallow beds. It was found that pressure fluctuations were relevant to the distribution mode of gas, jetting or bubbling, while gas flows through the orifices into the bed. At a constant open area ratio greater than 2.0%, a larger orifice diameter stabilized the jetting and better fluidization quality was obtained. On the contrary, a smaller orifice diameter was suggested in a very shallow bed.
