摘要
灵武煤田煤源充足,但煤质变质程度低,并且内水含量高,O/C比高,挥发分以及灰分含量偏高,属于难成浆煤种。以易成浆煤种张家峁煤制得的水煤浆各项参数为标准,以灵武煤难成浆煤种为试验对象,通过配煤,使其制得的水煤浆各项参数接近标准,从而扩大制浆煤种,并降低企业成本。
Lingwu coalfield contains abundant coal resources, but the coal is low degree of metamorphism, high content of water, high O/C ratio, high volatile content and high ash content, and is difficult to produce coal water slurry. In order to enlarge the coal types for coal water slurry and reduce business costs, coal is the test the standard. Zhangjiamao coal water slurry parameters is the standard and poor slurry coal in Lingwu object, by coal blending, the coal water slurry parameters of Lingwu coal was close to
