| 摘 要： | 基于商业软件Aspen Plus,运用Gibbs自由能最小化方法建立了气流床部分气化模型,预测气化炉入口参数(空煤比、汽煤比、热损失和碳转换率)对出口合成气的影响特征,模拟结果表明,随空煤比的增大,粗煤气中有效气体成分含量先增大后减少;随汽煤比的增大,粗煤气中H2含量增多,有利于部分煤气化再燃;随碳转换率的增大,粗煤气中有效气体成分含量增加,但提高程度不明显,因此针对部分气化不刻意追求碳转换率.

| Abstract: | Based on Aspen Plus,a model for entrained-flow bed coal gasifier partial gasification by the method of Gibbs free energy minimization was established. A series of calculations were carried out to predict the effects of different operation parameters on the performance of syngas. The parameters include air-coal mass ratio,steam-coal ratio and carbon conversion rate in gasifier. The results show that the increasing of air-coal mass ratio can reduce the effective composition in coal gas,which lead to decrease ... |
