Abstract Blast furnace iron manufacturers aim to reduce expensive coke usage through the injection of coal. This paper investigates contrasting agglomeration behaviour with a view towards optimising blast furnace operations and limiting furnace permeability issues. A drop tube furnace (DTF) was used to investigate the performance of two coal particle size specifications that were representative of injection coal sizes: pulverised (100%

高炉喷煤过程中炭团聚的研究

摘要 高炉铁制造商旨在通过注入煤来减少昂贵的焦炭使用量。本文研究了对比团聚行为，以优化高炉操作和限制高炉渗透性问题。下降管式炉 (DTF) 用于研究两种代表注入煤粒度的煤粒度规格的性能：粉状 (100%
