摘要
根基燃烧热平衡导出式,利用马钢现有高炉操作参数及原燃料条件,计算研究了风量、风温、富氧率、喷煤及鼓风湿度对理论燃烧温度的影响。研究得出,在马钢B高炉现有原燃料及操作工艺条件下,风量、风温、富氧率、喷煤及鼓风湿度每变化100 m^(3)/min、10℃、0.25%、5 kg/t、1 g/m^(3),理论燃烧温度分别变化1、8、8、8、8℃左右。
The effects of air volume,air temperature,oxygen enrichment rate,coal injection and blast humidity on theoretical combustion temperature were calculated and studied by using the basic combustion heat balance derived formula and the existing BF operating parameters and raw fuel conditions in Masteel.The results show that under the existing raw fuel and operating process conditions of B blast furnace of Masteel,the theoretical combustion temperature changes by 1,8,8,8,8 for each change of air volume,air temperature,oxygen enrichment rate,coal injection and blast humidity by 100 m^(3)/min,10℃,0.25%,5 kg/t and 1 g/m^(3).
