| 摘 要： | 通过分析高炉煤气的燃料组成特点和主要可燃组分CO和H2的化学反应机理及应用条件，分别选取了两种不同的用于蓄热式燃烧过程的化学反应路径，并完成了对试验烧嘴和试验炉炉内浓度场和温度场的模拟计算。对比试验结果表明：在高炉煤气蓄热式燃烧过程中，选用水汽化反应无论是对CO的分布预测还是对温度的全场分布预测都比单步无逆反应的Lavnov机理精准。 |

| Abstract: | Through analyzing the fuel composition of blast furnace gas and the chemical reaction mechanisms of CO and H2, two different chemical reaction mechanisms used for the blast furnace gas regenerative combustion are selected, and the combustion process of experimental burner is simulated with the FLUENT software. Based on the experimental results, the comparison of two chemical reaction mechanisms is completed, and the results indicate that water-vapor reaction mechanism is more suitable for the blast furnace gas regenerative combustion than global reaction mechanism proposed by Lavrov. |
| Keywords: | blast furnace gas regenerative burner chemical reaction mechanism numerical simulation |
