摘要
本文论述了由鼓泡流化床与从气力输送状态向循环流化床转化过程中的流体动力学现象；研究了湍流床开始出现到完全转化为湍流床及快床时，炉内气体速度变化的规律和相应的计算公式。对转化过程中的主要影响因素，进行了深入的试验研究。
This paper describes fluid bed and its fluid dynamics phenomenon which fluid bed transforms pneumatic transportation into circulating fluid bed. Variable-flow transformation regulation and computing formulae of turbulent fluid bed of boiler have researched. Principal factor influencing transformation process has been discussed thoroughly.
