摘　　要：建立了一种基于物料平衡、能量平衡和化学平衡分析的气化数学模型。利用该模型分别对松木屑、秸秆、稻壳和棉柴进行气化计算,获得不同水蒸气添加率的合成燃气成分、热值、气化效率及干燃气产率等气化指标,分析水蒸气添加率对高温空气气化的影响,为高温气化操作优化奠定基础。Based on material balance, energy balance and chemical equilibrium a mathematical model of high temperature air gasification was established. The gasification models pine sawdust, straw, rice husk and cottonwood were calculated, respectively. The effects of the steam fraction in the feed gas on the components and the HHV of syngas, gasification efficiency and net gas production were studied. The results provide the basis for the optimal operation of high temperature gasification.
