利用从钻探工作中和备采煤的大样(bulksamples)中搜集到的数据,可以运用台式电子计算机计算出选煤厂的工艺流程操作性能。选煤厂单项设备操作中的物料平衡可由一些方程组来确定,这些方程组被用于描述工厂操作性能。讨论了可洗性数据外推法、粒度分布外推法和其他关键数据的外推法,其目的在于把通常数目有限的质量数据扩大到能够满足设计需要。对于各条件和流程结构而言,流程仿真是能够进行的,只要调用的存贮器容量不超过32,000字长。本支列举了几个恰当的例子。
Using data collected from bulksamples from drilling operations and prepared coal mining, the performance of the process at a coal preparation plant can be calculated using a bench-top computer. The material balance in a single plant operation at a coal preparation plant can be determined by equations that describe the plant’s operational performance. Discusses extrapolation of washability data, extrapolation of particle size distributions, and extrapolation of other key data to extend the often limited number of mass data to meet design needs. Process simulation is possible for each condition and flow structure as long as the memory capacity invoked does not exceed 32,000 words. This section cites a few suitable examples.
