Coke is used in a blast furnace as a fuel and reducing agent. It provides the heat needed to melt iron ore and other materials to produce molten iron. Additionally, coke reacts with oxygen in the air to remove impurities from the iron ore, helping to create higher-quality molten iron.
Coke acts as a REDUCING AGENT. It removes oxygen ferrous oxide reducing it to iron
that would depend on the size of the blast furnace.
(Extraction of Iron in a Blast Furnace: Step 1 and Step 2)Coke reacts with oxygen from the air to form carbon dioxide and a lot of heat.Carbon + Oxygen -> Carbon Dioxide + heatC(s) + O2(g) -> CO2(g)Carbon dioxide reacts with more coke to form carbon monoxideCarbon Dioxide + Carbon -> Carbon MonoxideCO2(g) + C(s) -> 2CO(g)
iron is collected from blast furnace by drilling the taphole.Taphole is a hole drill and plug after cycle of time located in blast furnace bottom.

The burden in a blast furnace refers to the materials added to the furnace for the iron-making process. The burden typically includes iron ore, coke, and limestone. The burden calculation takes into account the proper proportions of these materials to achieve efficient iron production and maintain the desired chemical and physical balance within the furnace. Various factors, such as the quality of the materials and the operating conditions, influence the burden calculation in a blast furnace.
