摘　　要：通过在直径120mm,高度为2500mm的有机玻璃循环流化床内的冷态试验,确定了高岭土颗粒的类别,最小流化风速,操作气速对流化质量的影响关系,回料器正常工作时流化风、松动风、侧吹风的工作范围,为热态试验提供参数依据。By fluidizing calcination cold tests with coal-series kaolin in an organic glass circulating fluidized bed（CFB）,which diameter is 120mm and high is 2500mm.The effects of kaolin particle sort,minimal fluidization air speed and operative air-current speed on fluidization quality are studied.At the same time,the working ranges of fluidizing wind,loose wind and side wind are investigated.The test provides parameters for the subsequent hot test.
