摘要
在循环流化床锅炉炉膛内,可分为湍流床和快速床两个区域。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速床时,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,如床的当量直径。
In furnace of recirculating fluidized bed boiler, the turblent and fast fluidization regimes can be existed. The transition phenomena of hydrodynamics from bubbling and pneumatic transport to circulating regime are studied by the author and presented in this paper.
