Abstract Scope |
The transfer phenomenon and chemical reactions happening in raceway plays a key role in both metallurgical principle and industrial operation of blast furnace (BF). Hot air with high blasting velocity resulting in efficient gas-solid motion, which determines the velocity field and furthermore temperature field, influences the total rate of chemical reaction. A 1/3rd scale 3D cold sector experimental model taking blast air kinetic energy as similarity criterion is built to study the gas-solid motion phenomenon by using 80~110m/s gas inflow and real coke granule (average dimeter: 10~12mm). The results indicate that, to study the movement inside of raceway, using the blast air kinetic energy as similarity criterion is much more reasonable than the Reynolds number or Froude number. |
