The diagram above shows the inputs (left side) and outputs (right side) of an iron blast furnace. Create a material balance table using the compositions above, and the following conditions: The burden is 54% Fe. The Fe ratio in Fe₂O, and Fe,O, is 1:1. • The burden has 450 kg moisture ⚫ 850 kg slag is produced per 1000 kg pig iron ⚫ 1600 kg of coke is consumed per 1000 kg of ore. (coke composition: 94% carbon and 4% moisture) Assumptions: 1. All O₂ is consumed in the process. 2. The iron oxides are reduced indirectly. 3. N₂, H₂O, and Al₂O, are all inert. 4. All Fe in burden reports to pig iron.

The diagram above shows the inputs (left side) and outputs (right side) of an iron blast furnace. Create a
material balance table using the compositions above, and the following conditions:
• The burden is 54% Fe. The Fe ratio in Fe,0, and Fe;0, is 1:1.
• The burden has 450 kg moisture
• 850 kg slag is produced per 1000 kg pig iron
• 1600 kg of coke is consumed per 1000 kg of ore. (coke composition: 94% carbon and 4%
moisture)
Assumptions:
1. All O, is consumed in the process.
2. The iron oxides are reduced indirectly.
3. N2, H20, and Al,0, are all inert.
4. All Fe in burden reports to pig iron.
