为了研究氧气喷射角度对煤制甲醇转化炉中速度场的影响，利用 ANSYS 和 Fluent 软件构建煤制甲醇转化炉模型，研究了氧气喷射角度在0°、8°、11°和15°时对转化炉内速度分布变化，发现氧气喷射角度在0°时，转化炉内速度梯度最小，高速区域最小且沿轴向延展，火焰最稳定，不易出现火焰淬灭现象。

In order to study the influence of injection angle of oxygen on velocity field in conversion furnace of coal-methanol, the mathematical model of conversion furnace of coal-methanol was built with ANSYS and Fluent. The pressure field of conversion furnace of coal-methanol was simulated as the injection angle was 0°,8°,11° or 15°.The results show that the minimum velocity gradient can appear as the injection angle is 0°,the high speed area is the smallest and the region extends along the axial direction, the combustion of coke oven gas is the stablest,the quenching of flame is not easy to happen.
