高炉%理论燃烧温度%发热量
高爐%理論燃燒溫度%髮熱量
고로%이론연소온도%발열량
blast furnace%theoretical combustion temperature%calorific value
对高炉风口前理论燃烧温度进行了修正,建立了基于燃料(焦炭和煤粉)发热量的计算模型,即把燃料的不完全燃烧所放出的热量转化为燃料完全燃烧所放出的热量与燃料不完全燃烧的热损失之差。最后分析了煤种、煤比、富氧率等因素对理论燃烧温度的影响。

In this paper,some modifications on theoretical combustion temperature are made,and a model for calculation of theoretical combustion temperature based on the fuel (coke and coal)calorific value is developed.In the model,the incomplete combustion heat that is released by the fuel can be calculated by difference between the complete combustion heat and the heat loss because of incomplete combustion. Finally,the influence of some factors,such as coal species,coal ratio,oxygen enrichment ratio,on the theoretical combustion temperature are analyzed.
