Blast Furnace

Blast furnaces have grown considerably in size during the twentieth century. In the early days of the twentieth century, blast furnaces had a hearth diameter of 4–5 m and were producing around 100,000 THM per year, mostly from lump ore and coke. At the end of the twentieth century the biggest blast furnaces had between 14 and 15 m in hearth diameter, and were producing 3–4 …

Blast Furnace Process

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.

HOW A BLAST FURNACE WORKS

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".
