在传统理论燃烧温度计算模型的基础上,重点考虑了风口回旋区燃烧平衡时煤气成分的变化,强调化学平衡对理论燃烧温度的影响,提出了新的理论燃烧温度计算模型,通过采集与处理现场高炉数据以及编程技术实现了该模型的在线计算,并成功应用于国丰钢铁有限公司1号高炉,在高炉与主控室之间建立起一条理论燃烧温度信息通道,实时反映炉缸热状态。实践证明,该模型可以有效帮助工长了解高炉情况,从而对于保持炉缸状态活跃、高炉顺行、延长高炉寿命等起到了促进作用。

By researching the change of gas composition in coke circulating zone of blast furnace and analyzing the influence of chemical equilibrium on theoretical combustion temperature, a new theoreti- cal combustion temperature mathematical model was put forward based on the traditional one. The on- line computation of the model was realized and practiced in Guofeng Iron and Steel Co., Ltd. No. 1 BF by the technologies of data acquisition and processing and programming, which built a high speed in- formation channel of theoretical combustion temperature. Practice proved that the model could effec- tively help foremen to better understand the condition of blast furnace hearth, so that blast furnace sta- bility and long campaign life were promoted greatly.
