摘要
以贵州省开阳煤为研究对象,分析了开阳煤的煤质特性,按照烟煤成浆性难度指标D对开阳煤成浆性进行了评价.以开阳煤为原料配制水煤浆,对成浆性和流变特性进行了分析.结果表明,开阳煤比较容易制浆,煤浆具有较好的流动性,并表现出假塑性流体特性.添加剂YKL用量为0.15%时,煤浆更具有经济实用的优势.从煤浆黏度、流动性和流变特性分析得出,浓度63%的开阳煤水煤浆满足水煤浆加压气化技术的要求.
Kaiyang coal in Guizhou Province was used and systemically analyzed. The slur- ryability of Kaiyang coal was evaluated according to the slurryability index D of bituminous coal. The slurryability and rheological behaviour of Kaiyang coal water slurry were analyzed. The results show that the slurry prepared from Kaiyang coal has higher slurryability and good mobility. The rheo- logical behaviour of Kaiyang coal water slurry exhibits pseudoplasticity. Kaiyang coal water slur- ry has more economic and practical advantages when the amount of YKL accounted for 0.15% of Kaiyang coal. Kaiyang coal water slurry prepared by concentration of 63% meets the requirements of coal slurry pressurized gasification technology.
