摘　　要：提高热风温度是增加高炉喷煤、降低成本的主要手段 ,从理论燃烧温度、加热面积、热风炉的合理结构设计和操作 4方面来讨论提高热风温度的途径 ,分析了国内各种燃烧器的优缺点及各种可供选择的热风炉预热方案。同时讨论了烟气和冷风分配技术及消除热应力的方法 ,以便热风炉能达到 12 0 0℃以上风温和Increasing blast temperature is the main tool to increase PCI rate and reduce cost on BF.Four way to increase blast temperature are discussed in term of adiabatic flame temperature,heating area of chequer chamber,optimization of design and the operation.For hot blast temperature up to 1200 ℃ and more then 10 yeras lifetime of stoves,the advantages and disadvantages of different ceramic burners and the available gas and air reheating systems are reviewed.The methods for uniform distribution of flue gas and air in the chequer and elimination of stress in refractory are discussed.
