煤炭气化气流床气化炉的数学模拟

简要介绍了煤炭气流床气化的原理，总结了到目前为止煤炭气化气流床气化炉数学模拟情况，包括简单平衡模型和动力学模型（一维或多维），给出了这些数学模型模拟的主要内容（对气化过程流化力学、热力学、化学反应和质量、能量及动量平衡考虑情况）和模型的主要结论，以及典型气流床气化炉的模拟煤气组成和煤炭转化率数值与实验值或实际操作值的比较情况，结果显示主要组分模拟误差较小。

MATHEMATICAL MODELING OF COAL ENTRAINEDBED GASIFIERS

The coal entrained-bed gasification principle was briefly introduced in this paper. Based on relative documents, the mathematical modeling of coal entrained-bed gasifiers were reviewed.. These include simple equilibrium models and kinetic models (one-dimensional or two! three-dimensional). The main contents-about hydromechanics. thermodynamics, chemical reaction kinetics, and mass balance, energy balance, momentum balance, of the models were given out. The major results of models were also given. Finally, the comparison of computational results from the models with experimental or operational results were given. It can be seen that the errors of the main gas composition are very low.
