COREX‐3000熔化气化炉内煤气流分布直接影响炉内煤气利用率及炉料顺行，而布料制度是调节煤气流分布的主要手段。为探讨熔化气化炉布料模式，通过对物料在布料过程中的运动和受力分析，确定物料的落点位置并根据物料的安息角和质量守恒，建立了料面形状预测模型。在此基础上，结合数学知识和计算机技术，开发了 COREX‐3000气化炉的料面预测仿真软件，可预测万向布料器和 DRI‐flap 布料器不同布料制度下形成的料流轨迹、落点位置以及料面形状，为现场选择和调整布料制度提供参考。

The distribution of reducing gas in melter gasifier of COREX‐3000 directly influences gas utilization and burden descent.The charging of burden is a main method of regulating gas flow distribution.In order to reveal the burden distribution process,a mathematical model of forecasting the burden pile profile is established based on the impact position,angle of repose and the mass conservation of burden.The impact position of burden is determined by analyzing the material flow trajectory and force during charging process.Based on the mathematical model,an extended burden pile profile prediction software of COREX‐3000 melter gasifier is developed by combining mathematic knowledge and computer technology.Using this software,the burden trajectory,the impact position and the burden pile profile under various operations of the coal‐gimbal distributor and the DRI‐flap distributor can be easily obtained,which can provide reference data for adjusting the charging operation in practice.
