Abstract The gas distribution in direct reduction iron (DRI) shaft furnace has an important influence on DRI production process. Using the fluid analysis software ANSYS, the distribution of reducing gas flow and relative influencing factors in DRI shaft furnace were investigated. In the simulation analysis, pellets were simplified as porous media. The viscous resistance coefficient and inertial resistance coefficient measured in the experiment were used as the basic input parameters of the simulation process. The calculation results by the neural network to find the mapping relationship between the reduction part average pressure, transition part average velocity and the gas-based direct reduction shaft furnace process parameters. Finally, the shaft furnace ideal air distribution influencing factors are obtained through the calculation results by genetic algorithm optimization. The results show that the airflow distribution in the furnace has a direct relationship with the state of the factors which include the furnace top pressure and cooling gas outlet pressure. They impact the reasonability of the flow field in the shaft furnace.
