| 摘 要： | 在8种煤灰中添加不同矿物质作助熔剂,对煤灰熔融特性进行研究;并用灰色系统方法对8种煤灰的矿物质成分和综合成分与煤灰熔融特性的相关度进行研究,然后对实验方法与灰色系统关联度方法进行比较研究.结果表明:添加剂可以降低煤灰熔融温度,也可以升高煤灰熔融温度,添加剂CaCO3为30%时,F煤和D煤得到最低熔点分别为1 250℃和1 350℃;添加剂硼砂(Na2B4O7·10H2O)为15%时,F煤到最低灰熔点1 150℃,硼砂为20%时,D煤可到熔点1 300℃以下.根据关联度方法可得到:酸性矿物质是影响煤灰熔融温度的主要因素,钠系物质对灰熔融性的关联度比钙系物质影响大,数学方法计算结果与实验结果相吻合.
