Question

Write the reactions taking place in zones at the blast furnace

Answer 1

During the extraction of iron, the reduction of iron oxides takes place in the blast furnace. In this process, hot air is blown from the bottom of the furnace and coke is burnt to raise the temperature up to 2200 K in the lower portion itself. The temperature is lower in the upper part.

3Fe2O3 + CO → 2Fe3O4 + CO2

Fe3O4 + 4CO → 3Fe + 4CO2

Fe2O3 + CO → 2Fe3 + CO2 ...

hope it helps you....

Answer 2

Answer:

In the blast furnace, reduction of iron oxides takes place in different temperature ranges. Coke is burnt to get the required temperature upto about 2200K. The temperature is lower in the upper part. Hence, the reduction of iron oxides take place at lower portion.

Hope this Answer help you.
