摘　　要：以首钢迁安2号高炉热风炉为研究对象,采用数值模拟的方法求出不同操作条件下拱顶温度以及燃烧效率,并求得正确表达空气预热温度、煤气流量、空燃比以及煤气成分与拱顶温度和燃烧效率关系的数学模型.该模型在满足拱顶温度约束的条件下,以热风炉燃烧效率为优化目标,得到热风炉的最佳操作模式.With the hot blast stove in Shougang Qianan No.2 blast furnace as an object of study, the vault temperature and combustion efficiency under different operating conditions were solved by a numerical simulation method. Two mathematical models were constructed for the relations of vault temperature and combustion efficiency to air preheat temperature, gas flow, air-fuel ratio and gas composition. Considered the combustion efficiency of the hot blast stove as an optimization objective, the best operation mode for the hot blast stove could be obtained under the constraint condition of vault temperature by the mathematical models.
