山西典型无烟煤灰流动性的调控
, PP. 805-813
Keywords: 山西典型无烟煤,高硅铝,熔融性,黏温特性,助熔剂
Abstract:
？为满足气化炉液态排渣的要求,考察和比较了cao、mgo和fe2o3三种助熔剂对山西典型无烟煤煤灰流动性(熔融性和黏温特性)的影响.研究发现,mgo对硅铝比在1.2~2.0的高硅铝煤灰的流动温度降低最有效,其次为cao和fe2o3,这是由于使用各种助熔剂时生成不同的高温稳定矿物组分造成的.针对三种助熔剂建立了流动温度和完全液相温度的关系式,并得到了cao和fe2o3含量与流动温度的关系:ft=1593-9.573×wcao(r2=0.9429)和ft=1576-8.3306×wfe2o3(r2=0.9559),可以用于指导助熔剂的添加.cao无论从降低黏度数值或降低临界黏度温度都具有最好的效果.ca2+、mg2+、fe2+的电负性差异和高温下的产物不同是三种助剂对黏度数值影响不同的根本原因;mg2+、fe2+具有较小的离子半径以及单质铁在高温下析出是导致临界黏度温度较高的原因.
