摘　　要：采用Aspen Plus流程模拟软件对某拟建的IGCC示范工程的德士古煤气化炉进行数值模拟,通过考虑碳的不完全转换对计算流程进行了改进,并运用CPD模型预测煤热裂解的产物分布.研究了煤气化炉的重要操作参数(即水煤浆浓度、氧煤比、气化压力和气化温度)对气化结果的影响.在计算区间内,发现高浓度水煤浆浓度范围内,随浓度的增加,煤气的主要成分(H2+CO)的总含量增加.气化温度增大到1400℃左右时,煤气的主要成分随气化温度的进一步增加会趋于一个恒定值.Aspen Plus software is used to simulate a Texaco gasifier of an IGCC demon- stration project. By considering incomplete carbon conversion to improve simulation flowsheet and using CPD model to predict production of coal thermal decomposition, the effect of some im- portant operation parameters such as coal concentration of water coal slurry, oxygen/coal ratio, pressure and temperature in coal gasifier on the gasification production has been studied. The results show that within the calculation range, the percentage of main components increases as the coal slurry concentration increases within high coal concentration. And main components tend to be a constant value when temperature is about 1 400 centigrade.
