中文摘要：
研究了稻草及不同温度热解半焦颗粒在内径100mm、高1000mm的有机玻璃流化床中的流化特性．结果表明，稻草颗粒无法单独流化，而其热解半焦颗粒可单独流化；半焦颗粒的最小流化速度随粒径增大而增大，与床层高度无关，筛分粒径为0．45-0．9，0．18-0．45，0．125-0．18min的半焦颗粒的最小流化速度分别为0．19，0．16，0．14m／s；300-550℃温度范围内稻草热解半焦颗粒的流化特性无明显区别；半焦与稻草颗粒混合流化时，稻草颗粒不大于20％（ω）时床层有较好的流化质量，混合颗粒的最小流化速度都随混合颗粒中稻草含量增大而增大．
英文摘要：
Fluidization characteristics of straw and semi-char particles were investigated in a fluidized bed with I.D. of 100 mm and height of 1000 mm. The results show that straw particles can not be fluidized alone, but the semi-char particle fluidized well. The minimum fluidization velocities of semi-char particles increase with the particle size, but they are independent of the bed height, the minimum fluidization velocities of semi-char particles （with the sizes of 0.45-0.90, 0.18-0.45, 0.125-0.18 mm） are 0.19, 0.16, 0.14 m/s. The fluidization characteristics of semi-char particles at different temperatures （300-550 ℃） are similar. The fluidization characteristics of the mixture are well as long as the mass fraction of straw is less than 20%, but the minimum fluidization velocities of the mixture increase with the mass fraction of straw in the mixture.
