本文介绍了一种新型高炉喷煤添加剂,它具有改善喷煤燃烧特性,提高燃烧速度和燃烧效率,从而提高喷煤量,降低综合焦比的性能,同时还具有强化焦炭的骨架作用,改善高炉透气性,抑制舍铁炉料低温还原粉化的性能。高炉喷煤使用这种添加剂可取得显著的经济和社会效益。本文还介绍了测定该种添加剂性能及作用的实验方法。
In this paper, a new type of blast furnace coal injection additive is introduced, which has the advantages of improving the combustion characteristics of pulverized coal, increasing the combustion speed and combustion efficiency, thereby increasing the amount of coal injected and the overall coke ratio. Meanwhile, it also has the role of strengthening the coke skeleton and improving the blast furnace Breathability, inhibition of the low temperature reduction of the hearth refueling powder performance. Blast furnace coal injection using this additive can achieve significant economic and social benefits. This article also describes the determination of the performance of additives and experimental methods.
