Pig iron - blast furnace route | International Iron

The blast furnace gas that leaves the top of the furnace is a mixture of carbon dioxide, carbon monoxide, hydrogen and nitrogen and has a calorific value between 3,200 and 4,000 kJ/m³. After cleaning, it is used for a variety of purposes, including heating of the hot blast stoves [“cowpers”], in iron ore agglomeration plants and for

THE BLAST FURNACE - IRON PRODUCTION

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
