稀土元素对贫煤、贫瘦煤喷吹煤粉静态燃烧性能的影响

The influence of rare earth on the static combustion properties of meagre coal and meagre lean coal as pulverized coal

介绍了在静态燃烧条件下，对添加带有La2O3和CeO2的3种成分混合促进剂的混合煤粉进行了静态燃烧试验，考察了稀土氧化物对贫煤、贫瘦煤高炉喷吹煤粉燃烧性能的影响，并探讨了其助燃作用机理。

In the static combustion conditions, the static combustion test of the mixed pulverized coal, added with mixed accelerants containing La2O3 and CeO2 ,was carried out. It is investigated that how the rare earth oxides affected the combustion properties of meagre coal and meagre lean coal as pulverized coal in blast furnace, and the combustion-supporting mechanism of the rare earth oxides was explored.
