摘要：
An experiment was conducted to obtain data for pressure drop in risers of liquid-solid circulating fluidized beds, where two different risers (24 mm and 36 mm in diameter) were used. Tested particles were of glass and ceramics, and their diameter ranged from 2.10 to 4.95 mm. Water under ambient conditions was used as the fluidizing liquid. Pressure drop in the risers was measured using a reversed U-tube manometer. Based on the experimental data, a calculation method was derived for predicting the pressure drop in the riser, which could reproduce almost all the data with an accuracy of +/- 20%. Furthermore, the effect of independent parameters was investigated on the pressure drop component ratios consisting of the total pressure drop. (C) 2009 Wiley Periodicals, Inc.
