1)  circulating fluidized bed
循环床
1.
The measurement along a circulating fluidized bed boiler height of the gas conc e ntration and the combustion fraction distribution has demonstrated that the majo r difference between a bubbling fluidized bed and a circulating fluidized one co nsists in their radically different combustion behavior in a dense phase zone.
循环床锅炉沿床高的烟气浓度及燃烧份额分布测试结果证明 ,鼓泡流化床和循环流化床的重要差异表现为密相区燃烧行为的根本不同 ,由于床料平均粒径较低 ,循环床密相区的流动不同于鼓泡床 ,导致气固两相之间的传质阻力增加 ,从而影响燃烧反应 ,密相区的燃烧行为表现为欠氧。

补充资料:循环流化床
分子式:
CAS号:

性质:在气速大于颗粒的自由沉降速度下进行流化,颗粒被气流带出,把气体与固体分离后,固体又循环回床层中所构成的流化床。它在工业上有很多用途。例如用于催化裂化,催化剂在提升管中被重油蒸气流化并输送,同时发生反应。在提升管顶部失活的催化剂与油气分离后进入另一个流化反应器(再生器),被空气流化并进行再生。再生后的催化剂又循环回提升管,构成一组循环流化床的催化裂化反应器。
