| 摘 要： | 在Φ0.205 m×7 m高密度循环流化床冷态实验台上,分别对三种不同出口结构在不同的试验条件下进行研究。实验结果表明:在高密度条件下,光滑出口结构使床内呈典型的指数衰减规律;突变出口对整个床高的轴向颗粒浓度均增加。

| Abstract: | Influences of the outlet structure on the flow characteristics are studied in the high density circulating fluidized bed.The bed diameter is 205 mm,and the height is 7 000 mm.The results show that the solid concentration of smooth type is exponential decay type.The axial solid concentration of the whole riser is increased by unsmooth exit. |

| Keywords: | high density circulating fluidized bed structure of outlet circulating flow rate solids concentration |
