| Abstract: | A two-dimensional multiphase CFD model was developed to simulate combustion process of two kinds of blended coal and pulverized coal in use in Xinyu Steel inside combustion stove.By applying the model,the temperature field and coke distribution,which were formed during their combustion,was simulated.The results show that two kinds of blended coal have a much better combustion properties than pulverized coal in use in Xinyu Steel.Burning rate and reaction properties were measured by Thermogravimetry,which we... |
