摘要
针对准格尔煤田6号煤煤灰含有较高铝氧化物成分的特征,采用以KF为助熔剂开展焙烧活化正交试验,考察不同焙烧温度、焙烧时间以及助剂的添加量对煤灰中铝浸出率的影响。实验表明:煤灰中铝的浸取率的焙烧活化最佳实验条件为煤灰与KF质量比1∶1、700℃高温焙烧1h时,煤灰中铝的浸取率可达到95.60%。
In allusion to the characteristics of higher aluminum oxide component in coal ash from coal No.6,Jungar coalfield,carried out roasting activation orthogonal experiment using KF as fluxing agent.The impact from different roasting temperature,roasting time and fluxing agent dosage on coal ash aluminum leaching yield has been observed.The experiment has shown that the best experiment condition is under mass ratio 1∶1 of coal ash and KF,700℃temperature for one hour,the leaching yield of aluminum from coal ash can be 95.60%as high.
