长焰煤热解产物高效利用的研究

Study on how to use pyrolysis product of flaming coal with high-efficiency

对长焰煤及其半焦产物进行了高炉喷吹技术性能研究。实验表明,长焰煤的可磨性、燃尽率优于半焦,但是半焦的热值高、安全性好、挥发分低,比长焰煤本身更适用于高炉喷吹。

This paper studies on technical properties of the blast furnace injection for flaming coal and its semi coke products. The result of the experience shows that grindability and burning rate of flaming coal are better than that of semi coke,while semi coke has higher calorific value,better safety performance,lower volatile,and more suitable for blast furnace injection than flaming coal.
