摘要
当前影响高炉喷煤量提高的因素是多方面的。提高风温、富氧、维持合理的理论燃烧温度,选择合适的煤粉粒径、采用混合喷吹以及解决好均匀喷吹等工艺技术问题是提高喷煤置换比和扩大喷煤量的重要手段。
The factors which influences the increase of coal injection rate are different.Increasing blast temperature,oxygen enrichment of blast,keeping a suitable theoretical combustion temperature,optimizing coal particle size,injecting mixed coal and improving even distribution of coal,etc.are important means on raising replacement ratio and increasing coal injection rate.
