實驗裝置使用透明壓克力板製成之單格床與雙格床床體，單格床尺寸為長100 mm、寬100 mm及高600 mm。雙格床為兩個上述尺寸單格床組成，雙格床中間隔板設有10 mm及20 mm之孔口，分別位於40、80及120 mm高。雙格床於分散板上方40、80及120 mm床壁處設有3組壓力接頭並裝置壓力探針，以量測孔口兩端壓差。實驗以粒徑177~210 μm的河砂探討不同床高、孔口直徑、孔口高度、稀疏床堰高及稀疏床氣體速度等操作變數，對於內通式流體化床之孔口兩端壓差與粒子通過堰速度的影響。
在探討操作變數對粒子通過堰速率影響的實驗結果顯示，以低孔口高度、大孔口直徑、低堰高、高稠密床床高及高稀疏床氣體速度可得到較高的粒子速率，其中以改變孔口直徑所造成的影響較大。
由探討孔口兩端壓差與粒子速率關係的實驗結果顯示，在單格床中，粒子通過孔口的速率與孔口兩端壓力差兩者為冪次關係，而雙格床在同一孔口高度時，粒子越過堰的速率與孔口兩端壓差兩者為線性關係。由單格床的壓差與粒子通過孔口速率的關係得到排放係數CD及在雙格床的實驗得到孔口壓差與粒子速率的經驗式。

The one-compartment fluidized bed and two-compartment fluidized bed used in this study are made of transparent Plexiglas plates. The dimension of one-compartment fluidized bed is 100 mm long, 100 mm wide and 600 mm high. The two-compartment fluidized bed is consisted of two one-compartment fluidized beds. In latter one, diameters of orifice on the partition plate are 10 mm and 20 mm; the heights of orifice are 40 mm, 80 mm and 120 mm above the distributor. The pressure probes, which are used to measure the orifice pressure drop, installed at 40 mm, 80 mm and 120 mm heights above the distributor. The particles used in this study are sand particles with size range between 177~210 μm. The effect of lean bed superficial gas velocities, orifice diameters, heights of orifice, heights of dense bed and heights of weir on orifice pressure drop and solid flow rate through the bed were studied in this system.
The result shows operating at low orifice height, large orifice diameter, low weir height, high dense bed height and high lean bed superficial gas velocity would give higher solid flow rate, and the effect of orifice diameter was more obvious. In one-compartment fluidized beds, orifice pressure drop and solid flow rate through the bed could be expressed as a power law relationship. In two-compartment fluidized beds, at same height of orifice, both orifice pressure drop and solid flow rate through the bed could be expressed as a linear relationship. A discharge coefficient in one-compartment fluidized beds and a correlation equation in two-compartment fluidized beds could be obtained from these experimental data.
