    • Abstract
  • The top gas recycling oxygen blast furnace is a new iron making process that can effectively increase the coal ratio and reduce carbon dioxide emissions. However, the complex combustion conditions will make the combustion of coal in the raceway and the behavior of the lower part of the blast furnace change greatly. In order to understand the complicated phenomenon of pulverized coal injection under the new oxygen blast furnace process, a three-dimensional CFD model has been developed to simulate oxygen coal lance-blowpipe-tuyere-raceway-coke bed of oxygen blast furnace. The temperature field, the concentration field and the flow and combustion characteristics of pulverized coal were investigated. The results indicate that the temperature is significantly increased, the high temperature area is enlarged, and the carbon dioxide content is increased of the raceway under the oxygen blast furnace. And the carbon monoxide content in the coke bed increased significantly. In addition, the coal burnout increased by 10.24% compared to that of the TBF.
