摘　　要：通过COREX喷煤整体和区域模型计算分析,研究了喷煤对块煤用量、理论燃烧温度、风口煤气量等重要参数的影响。计算结果表明:随着喷煤量的增加,风口煤气量增大,块煤用量和理论燃烧温度均降低。最后,建立了二维COREX熔化气化炉热态模型,利用石蜡模拟矿石、玉米粒子模拟焦炭。在热态物理模拟试验中,考察了矿/(块煤+焦)体积比、风温和风量等操作参数对COREX熔化气化炉炉况的影响。Through analysis of the block model and regional model of COREX PCI process,the effect of PCI on the lump coal consumption,the gas volume of the raceway and the theoretical flame temperature are studied in this paper.The results show that when the PCI is increased,the gas volume of the raceway is enlarged;the lump coal consumption and the theoretical flame temperature are decreased.A two-dimensional（2D） physical thermal model is established in this paper,then the state inside the model is simulated with the particles of wax and maize.The results show that the operating parameters affected the COREX melter gasifier clearly.
