| 摘 要： | 本文建立了流化床焚烧炉中粒子扩散方程，通过求解方程，得到了鼓泡床和内旋流床中颗粒扩散特性，并与试验结果进行了对比，两者符合较好。结果表明鼓泡床横向扩散能力较差，而内旋流床有很好的横向扩散特性，非常有利于废弃物在床内的快速扩散。

| Abstract: | In this paper, a particle diffusion equation has been developed and solved for fluidized bed incinerators. And the characteristics of particle diffusion is obtained for a bubbling bed and internally circulating fluidized bed (ICFB). The theoretical results are been compared with the experimental results and they coincide fairly with each other. The results show that there is a bad lateral particle diffusion characteristics in bubbling bed. However, there is a good lateral diffusion characteristics in ICFB, which is very useful to the fuel quick diffusion in the bed. |
