摘要
通过对预热器内石灰石和窑尾烟气换热过程分析,以堆积床为模型计算窑尾烟气在整个预热器中的珚Nu数,并进入科尔伯恩因子,从而得到窑尾烟气和石灰石的对流换热系数。
By analysis heat transfer between lime stones and hot-air coming from rotary kiln, it used accumulation bed model to get Nu. Finally, and it used Colburn . Finally it gets convective heat transfer coefficient between lime stones and hot-air in pre-heater .
