摘　　要：基于Aspen Plus软件,应用Gibbs自由能最小化方法,建立数学模型,对干煤粉气流床气化制工业燃气过程进行数值模拟。模拟计算结果表明,此模型可以比较准确地预测干煤粉气流床气化炉的出口气体成分。基于此模型,分别考察了氧煤比、蒸汽煤比对气化温度和有效气产量的影响,并确定出神华煤种合理的氧煤比为0.8和蒸汽煤比为0.1。Based on Aspen Plus software, the Gibbs free energy minimization method was used to establish the mathematical model and develop the numerical simulation of the entrained-flow pulverized coal gasification process. The simulation result indicated that this model could fairly accurately predict the composition of the product gas of the gasifier. Based on this model, the impact of the oxy-coal ratio and the steam-coal ratio on the gasification temperature and effective gas production was investigated. With this model, it was determined that the proper oxygen-coal ratio for the Shenhua coal was 0.8 while its steam coal ratio 0.1.
