The blast furnace

The air contains oxygen. The oxygen allows the coke (carbon) to burn and form carbon dioxide. This reaction gives out heat, i.e., it is exothermic, so it heats up the furnace.

The air contains oxygen. The oxygen allows the iron ore to burn and form carbon dioxide. This reaction gives out heat, i.e., it is exothermic, so it heats up the furnace.

The air contains oxygen. The oxygen allows the limestone to burn and form carbon monoxide. This reaction gives out heat, i.e., it is exothermic, so it heats up the furnace.
