Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2. A blast of hot air is blown into the furnace from the bottom. 3. Coke is the fuel that supplies additional heat, increasing the temperature of the charge. 4.

dirty gases. These gases exit the top of the blast furnace and proceed through gas cleaning equipment where particulate matter is removed from the gas and the gas is cooled. This gas has a considerable energy value so it is burned as a fuel in the "hot blast stoves" which are used to preheat the air entering the blast furnace to become "hot blast".

A typical blast furnace may be up to 32 metres in height and 10 metres in diameter. They have thick steel sides, lined with refractory bricks, to ensure that heat is not lost. 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 ...

Blast Furnaces. The blast furnace (BF) is the most widely used ironmaking . process in the U.S. A major advance in BF ironmaking has been the use of pulverized coal which partially replaces metallurgi-cal coke. This results in substantial improvement in furnace efficiency and thus the reductions of energy consumption and greenhouse gas emissions.
