Abstract:Based on the analysis of coal combustion process,the coal combustion process is separated into coal drying process,coal pyrogenation process,combustion process and slag separation process in this study. Each process is analyzed in detail and the corresponding mathematical model is established. The optimization of conventional separator model is focused. The model of coal combustion process is applied to Texaco gasifier. The simulated data is consistent with that the literature reported,which proves that the model of coal burning process established is reasonable. It is basic to the numerical simulation study of coal combustion process and can be applied in the numeri....
