摘要：Drying technology of low rank coal, which is the leading technology of low rank coal thermal chemical processing, plays an important role for the efficient use of low rank coal. It has made clear the influence factors of low rank coal drying process and effect of related factors by studying low rank coal occurrence form of moisture and the drying mechanism. In the paper, it has carried on the experimental study in drying characteristic under the condition of fluidized drying in the tube furnace with YuZhou Long-flame coal as the research object, and obtained the correlation curve of the particle size, fluidization velocity, drying temperature, drying rate and the influence factors. At last, according to the experiment and the system economy, the drying process parameters are optimized: the drying temperature is 210 °C, the fluidization air velocity is 1.6 m/s, the drying time is 5 minutes.
