| 摘 要： | 在冷态实验条件下,对内径为0.28m,高为10.0m的循环流化床中木屑颗粒在Loop seal返料器中的流动特性和规律进行了研究,重点考察了提升管操作气速Ug、Loop seal返料器的输送风量Q1和侧向吹风量Q2改变对颗粒循环流率Gs的影响。实验发现,改变提升管操作气速Ug对循环流率的影响不大;通过Loop seal的颗粒循环流率Gs随着输送风量Q1和侧向吹风量Q2的增加而增大;改变侧向吹风量对循环流率的影响要比改变输送风量大得多。根据实验结果,对王擎给出的循环流率Gs的计算关联式进行了修正。 |

| Abstract: | The flow characteristics of sawdust particles in loop seal of a circulating fluidized bed were investigated.This paper focused on the effect of different operation conditions such as operation gas velocity,the transport gas volume Q1 and the auxiliary transport gas volume Q2 on the solids circulation rate Gs.The experimental equation modified from Wang's on solids circulation rate Gs and operation conditions were also given. |
| Keywords: | sawdust circulating fluidized bed Loop seal solids circulation rate |
