Orthogonal experiment and SEM research on coal fines dewatering by microwave heating
Pages: 1-3,45
Year: Issue:  1
Journal: Research on Iron and Steel

Abstract: 采用正交试验设计方法,通过SEM分析,研究了微波加热比功率、试样初始水分质量分数、细粉煤粒径大小以及加热时间等因素对细粉煤微波加热除湿的影响.在本实验条件下,得出细粉煤微波加热的最优化除湿条件为:比功率8 kW/kg,初始水分质量分数10 %,细粉煤粒径在1.25~2.5 mm,加热时间8 min.极差、方差分析表明:微波加热的比功率和加热时间是影响细粉煤微波除湿的主要因素,细粉煤粒径大小对除湿效...
