An advanced air‐blown two‐stage entrained‐flow coal Mitsubishi Heavy Industries (MHI) gasifier is numerically studied under actual conditions. The simulation results are verified first with actually measured data of an industrial MHI gasifier. Then, the effects of different parameters such as the sizes of pulverized coal particles, devolatilization parameters, and operating pressure on the gasifier performance are investigated. The results indicate that as the coal particle size increases, the syngas temperature at the gasifier exit rises while the reactivity of the coal particle decreases. Reducing the operating pressure can have a negative effect on the gasifier throughput while the opposite trend is observed for higher operating pressure.

基于数值模拟的两级气流床气化炉性能评估
在实际条件下，对先进的风吹两级气流床三菱重工（MHI）气化炉进行了数值研究。首先使用工业MHI气化炉的实际测量数据验证仿真结果。然后，研究了粉煤颗粒大小，脱挥发分参数和操作压力等不同参数对气化炉性能的影响。结果表明，随着煤颗粒尺寸的增加，气化炉出口处的合成气温度升高，而煤颗粒的反应性降低。降低工作压力会对气化炉的生产量产生负面影响，而对于更高的工作压力则观察到相反的趋势。
