采用数学模型预测高炉富氧喷吹煤粉的燃烧过程，数学模型包括气相流动、煤粉挥发分的热解和燃烧、残炭的燃烧、辐射传热和固体颗粒相的运动等子模型．模拟结果表明，单筒煤枪和热风混合效果不好，不利于煤粉燃烧；由于直吹管和风口空间小，因而富氧对煤粉燃烧率影响不大；富氧可提高风口端部平均氧含量，有利于煤粉在回旋区内燃烧．
The mathematic model is used to predict the combustion process of pulverized oxygen-rich pulverized coal injection. The mathematical models include gas phase flow, pyrolysis and combustion of pulverized coal volatiles, combustion of residual carbon, radiative heat transfer and movement of solid particles. The simulation results show that the mixing effect of single-cylinder coal gun and hot air is not good, which is not conducive to the combustion of pulverized coal. Because of the small space of straight-blowing pipe and tuyere, oxygen enrichment has little effect on the combustion rate of pulverized coal. Content, is conducive to burning coal in the raceway area.
