摘　　要：为了能够更好的模拟Gsp煤气化炉,建立了新的气化炉模型。Gsp煤气化炉内部反应较为复杂,温度、压力较高难以模拟,为了对气化炉建立数学模型并且对生产工艺进行动态模拟,通过对煤气化炉装置物料流动方式的分析,结合煤气化反应的动力学、物料衡算和能量衡算,简化反应过程的次要因素,最终用通用化工动态流程模拟优化软件平台建立了气化炉反应器的串联全混流模型,并且选用四阶龙格-库塔法进行求解计算。反应器动态模拟的数值结果与实测值相比较,发现通过优化计算的结果可以把误差控制在1%以内,证明建立的数学模型能够很好地模拟工艺流程,为模拟Gsp煤气化炉提供了一种新的思路。The reactor of gasifier is complex and the gasifier has high temperature and pressure. So it is difficult to simulate. In order to built the dynamic simulation for the gasifier reactor. We focused on establishing the dynamic mathematical models for the gasifier reactor. Through analysis of material flow, reaction kinetics, mass balance, and energy balance, and DSO simulation software, the Continuous Stirred Tank Reactor model is established and the Four order Runge Kutta method is used to solve the model. The deviation can be controlled within 1% by optimizing the calculation results. The results showed the simulation is consistent with actual production, indicating the models can simulate the process very well, providing a new direction for dynamic simulation of gasifier.
