| Abstract |
Gas flow is affected by physical properties of burden in packed bed of iron blast furnace. The gas permeability with the different size of ore in a packed bed is studied to show the following results. 1. Apparent and bulk density of the sinter in 4DL in POSCO are decreased with the ore size. 2. Pressure drop equation of packed bed is satisfied with Ergun equation. 3. Pressure drop is increased with the addition of -5㎜ sinter ore. |
