摘　　要：利用正交试验方法对神华煤进行实验室的水煤浆成浆性研究,采用多因子一次回归,经过方差分析得到回归方程,再通过计算机程序优化得到最佳的添加剂配比和粒度分布。结果表明,通过该方法进行的优化配方有利于提高煤的成浆性,优化前后煤的最高成浆浓度分别为59.51%和62.36%,而且级配后的浆体稳定性和流变性也较未经级配的浆体有了不同程度的改善。An orthogonal experiment was conducted in laboratory to investigate the Shenhua coal water slurrying property. The regression equation was obtained by multi - factor regression and variance analysis,and the optimal additives ratio and particle size distribution were gained through a computer program optimization method. The results show that the optimization method can raise solid concentration of the Shenhua coal water slurry, and the concentration is increased from 59.51% to 62.36%. Furthermore,the stability and rheology of the coal water slurry are also improved after particle size gradation.
