以新疆库尔勒煤为煤样,研究了在以萘磺酸盐为添加剂的情况下,采用粒度级配方法制备水煤浆的最佳条件。实验结果表明,①萘磺酸盐的添加量宜为0.3％(以干基煤为标准)；②1＃煤样粗细粒度宜按6∶4级配,2＃煤样粗细粒度宜按5∶5级配；③1＃煤样可制得质量分数约为59％的水煤浆,2＃煤样可制得质量分数约为62％的水煤浆,且均表现出一定的屈服假塑性,可以满足水煤浆气化技术的要求。

Taking the coal in Korla of Xinjiang as a coal sample, author has researched the optimal condition for preparing the water coal slurry by means of granularity classdistribution method under situation taking naphthalene sulfonate as an adding agent. Experimental result indicates that:( 1 ) Adding quantity of naphthalene sulfonate should be 0. 3 %( taking dry base coal as standard);(2) Granularity of 1#coal sample shall be proportional as 6∶4; Granularity of 2# coal sample shall be proportional as 5∶5;(3) 1#coal sample can make water coal slurry with mass fraction of about 59%, 2#coal sample can make water coal slurry with mass fraction of about 62%, moreover all showing definite pseudoplasticity, it can meet requirement for gasification technology of water coal slurry.
