Modelling on effects of operation parameters on entrained flow coal gasification (Ⅰ): Model establishment and validation

WU Xue-cheng, WANG Qin-hui, LUO Zhong-yang, FANG Meng-xiang, CEN Ke-fa(Institute for Thermal Power Engineering, Clean Energy and Environment )  
A kinetic coal gasification model combining chemical equilibrium was developed to evaluate and optimize gasifying parameters in entrained flow bed gasification. Heterogeneous and homogeneous reactions occurred in coal pyrolysis and gasification processes such as C-O_2, C-H_2O, C-CO_2, C-H_2 and CO-O_2, H_2-O_2, CO-H_2O, CH_4-H_2O were considered in this model. Model calculating results are in good agreement with the measurement data from entrained flow coal gasifiers. Model simulations of coal gasification processes in entrained flow coal gasifiers were found to be reasonable. It implies the established model may be used to predict the effects of operation parameters on entrained flow coal gasification.
