摘要
以文献为基础，简要介绍了文献中的流化床气化炉的数学模型，将其分为热力学平衡模型和速率模型；重点分析了速率模型，根据所用流体力学模型不同将其分为全混模型、两相模型、鼓泡床模型和气泡汇集模型。最后针对现状提出了流化床气化炉数学模型的发展方向。
Mathematical models reported in the literatures are introduced briefly in this paper, and can be breadly classified into thermodynamic and rate mod-els.On the basis of the hydrodynamic model used,rate models are classified into four groups,well mixed, two phase, bubbling bed,and bubble assemblage models.Finally,some developing respects of fluidized coal gasifier model are raised.
