基于Alfred模型提高神府煤水煤浆成浆性

Study on Improving Coal Water Slurry Ability of Shenfu Coal Based on Alfred Model

摘要: 为提高神府煤水煤浆的成浆性,结合干法制粉工艺,利用Alfred模型对神府煤煤粉粒度进行计算模拟,计算结果表明,实际煤粉粒度在10μm以下的含量较低,通过细粉级配优化,使实际分布更接近理论模型分布,从而大幅改善了神府煤粉成浆性,使成浆浓度提高至63%以上,静置稳定性大于2周。

Abstract: In order to improve the coal water slurry ability of Shenfu coal,in combination with dry powder produced process,the paper used the Alfred model to calc ulate the particle size distribution of Shenfu coal powder. The results showed that the actual content of the coal particle size less than 10 μm was lower,so fine coal pow der gradation optimization was used,in order to make the real particle size distribution was closer to the Alfred model distribution. Meanwhile,coal water slurry ability of Shenfu coal power was improved,the concentration of coal water slurry was increased to more than 63%, static stability could reach to more than two weeks.
