三个阶段平衡模型基于正的白杨在 Texaco 类型煤 gasifiers 为煤气化被开发计算产品气体,碳变换,和气化温度的作文。模型被划分成包括热分解和燃烧舞台,字符气体反应阶段,和煤气的阶段反应的三个阶段舞台。在热分解和燃烧舞台生产的水的部分被假定涉及第二个阶段与未燃的碳反应。碳变换然后被表示为温度的功能的蒸气参予比率在第二个阶段估计。并且煤气的产品作文在第三个阶段从煤气的阶段反应被计算。模拟结果与出版试验性的数据一致。
A three stage equilibrium model is developed for coal gasification in the Texaco type coal gasifiersbased on Aspen Plus to calculate the composition of product gas, carbon conversion, and gasification teml~erature. The model is divided into three stages including pyrolysis and combustion stage, char gas reaction stage, and gas p.hase reaction stage. Part of the water produced in thepyrolysis and combust!on stag.e is assumed to be involved inthe second stage to react with the unburned carbon. Carbon conversion is then estimated in the second stage by steam participation ratio expressed as a function of temperature. And the gas product compositions are calculated from gas phase reactions in the third stage. The simulation results are consistent with published experimental data.
