【摘要】 要获得良好的喷吹效果,需要把不同成分的煤种按喷煤质量的要求进行精确配煤。本文通过约束条件控制混煤的质量,将混煤成本作为目标函数,将模拟退火算法作为最优化算法,建立喷煤优化配煤数学模型。在模型的应用中,得到的最优配比的各项指标均达到了高炉对喷吹煤粉的质量要求,优化配比的成本降低了11元/t,降低了喷煤成本。更多还原

【Abstract】 To obtain good results of coal injection,it needs accurate coal blending by the mass of injected coal using coals with different compositions.This article builds a mathematical model on coal blending optimization of coal for blast furnace injection.This model takes the cost of blended coal as the target function,takes the simulated annealing algorithm as the optimization algorithm and controls the quality of the blended coal by the constraint conditions.In the application of the model,all the indexes of the the optimum proportion meet the requirement of the blast furnace to the blended coal.The cost of blended coal of the optimum proportion reduced 11 yuan/t,reducing the cost of the coal injection.更多还原
