| 摘 要： | 借助Aspen Plus模拟软件,对粉煤加压气流床气化工艺进行研究。采用工业数据,对计算模型进行验证,发现计算结果与实际生产运行数据基本吻合,有效合成气最大相对误差不大于3%。研究表明,氧煤比和蒸汽煤比对气化性能的影响较大,随着蒸汽煤比的增加,有效气成分降低;随着氧煤比的增加,有效气含量存在最大值,同时冷煤气效率也存在最佳值。此外,气化温度随氧煤比的增加而增加,随蒸汽煤比的增加而降低。

| Abstract: | Mathematical simulation and performance study of the pulverized coal entrained-flow gasification process were carried out. The results were in good agreement with the on-site data, the maximal relative error being less than 3%. The results indicated that with the increase of the ratio of steam to coal, the effective gas yield decreased; and with the increase of the ratio of oxygen to coal, the effective gas content was at its maximal value and the cold gas efficiency was also at its maximal value. Furthermore, the gasification temperature increased with the increase of the ratio of oxygen to coal, and decreased with the increase of the ratio of steam to coal. |
