摘要
在循环流化床锅炉炉膛内，分为湍流床和快床２个区域，论述了由鼓泡流化床与从气力输送状态向循环流化术转化过程中的炉内流体动力学现象，研究了湍流床开始出现到完全转化为湍流化床及快床时，炉内气体速度变化的规律和相庆的计算公式。
In the furnace of recirculaimg fluidized bed boiler, here turblent and last flu-idization regimes can be existed. The transition phenomena of hydrodynamics from bubbling fluidized bed and pneumatic transport transition to turblent and fast fluidized bed and the effect of bed temperature and solids velocity on transition process are studied.
