循環固気流動層用反転流サイクロンの分離性能 Separation Performance of a Reverse-Flow Cyclone for a Circulating Solid-Gas Fluidized Bed System 伊地知, 和也 IJICHI, Kazuya 西山, 靖志 NISHIYAMA, Yasushi 田中, 安彦 TANAKA, Yasuhiko 501 Experiments were performed to investigate, for silica sand with a mean size of 145 μm and a particle density of 2640 kg/m^3, the effect of inlet air velocity and aeration velocity on the separation performance of a 50 mm dia. standard cyclone for a circulating fluidized bed system wity a 20 mm dia. riser. The results indicated that the inlet solids holdup decreases and the pressure drop across the cyclone increases with an increase of the inlet air velocity. Increasing the aeration velocity over a critical value results in a significant drop in the separation efficiency of the cyclone at high inlet velocities. departmental bulletin paper 鹿児島大学 Kagoshima University 1988-11 VoR application/pdf 鹿児島大学工学部研究報告 30 185 188 The research reports of the Faculty of Engineering, Kagoshima University 0451212X AN00040363 https://ir.kagoshima-u.ac.jp/record/12693/files/AN00040363_v30_p185-188.pdf http://hdl.handle.net/10232/11474 https://ir.kagoshima-u.ac.jp/records/12693 jpn open access
