• 中文摘要： 本文研究旋風分離器裡氣體與固體粒子的熱傳遞,量測旋風分離器管壁及氣體的溫度分布。由熱平衡估測氣體與粒子間的熱傳係數,並求其與粒子大小,粒子濃度及氣體流速的關係。我們發現所獲得的氣體-固體粒子間熱傳係數比在流體化床,固定床或瞬間乾燥器的值還小。同時在本文中,我們也建立一簡單模式來解釋旋風分離器的熱傳。
• 英文摘要： The heat transfer between gas and solid particles in a cyclone was studied. The temperature distributions of the gas and wall in the cyclone were measured. The heat transfer coefficients between gas and solid particles were estimated by heat balance, and were correlated to particle size, particle concentration, and gas flow rate. It is found that the heat transfer coefficient between gas and particles obtained in this study is smaller than that in the fluidized bed, fixed bed, or flash dryer. A simple model based on the surface renewal theory has been developed to interpret the heat transfer in a cyclone.
