摘　　要：高炉喷煤技术是强化冶炼、增产降本的重要手段,优化和完善喷煤系统能为“高产、低碳、经济、环保”炼铁创造条件。文章在分析现有高炉喷煤系统设计存在问题的基础上,提出了原煤贮运、制粉、喷吹、烟气等系统的改进措施和评价方法。Blast furnace coal injection technology is an important means to strengthen smelting,increase production and reduce cost.Optimizing and improving the design of coal injection system can create conditions for“high-yield,low-carbon,economical,and environmentally friendly”ironmaking.Based on the analysis of the existing problems in the design of blast furnace coal injection system,improved measures and scheme evaluation methods in systems such as raw coal storage and transportation,pulverizing,injection,and flue gas preparation are proposed.
