【摘要】 高炉喷煤可以有效的降低焦比,喷煤量过大会导致未燃煤粉过多,影响炉况顺行,因此研究煤粉的燃烧率至关重要。前人大多数通过实验确定煤粉燃烧过程中的动力学参数。本文结合高炉喷煤过程,依据煤粉工业分析值,通过建立数学模型来计算煤粉燃烧反应动力学参数。模型能够计算煤粉的燃烧率,同时可以预测不同的富氧量、不同的风温、不同的煤粉粒径对燃烧率的影响。更多还原

【Abstract】 Pulverized coal injection in blast furnace can effectively reduce the coke rate.Large quantity of coal injection can cause that there is too much unburnt pulverized coal and affect the smooth running of blast furnace.So studying the combustion rate of pulverized coal is very important. Previous often compute the kinetic parameters by experiment.However,this paper computes kinetic parameters by mathematics model on the base of previous works according to industry analysis value.The model can compute the combustion rate and predict the influence of different oxygen-rich,blast temperature and particle size to the combustion rate.更多还原
