Relationship between crystal mineral composition of Huainan coal ash and its flow temperature

  • 摘要: 选取10种不同灰熔融温度的淮南煤,利用典型煤灰化学组成预测煤灰熔融温度的经验公式,对其煤灰流动温度进行了研究,发现预测精度不高;借助X射线衍射K值法分析计算了淮南煤灰的晶体矿物组成,并对晶体矿物组成与淮南煤灰流动温度的关系进行了关联,提出了利用晶体矿物组成预测煤灰流动温度的回归公式,揭示了淮南煤灰中晶体矿物组成与煤灰流动温度的内在关系,利用该公式计算的煤灰流动温度与实测值之差的绝对值小于国标规定的误差值(再现性小于等于80℃)。
