Blast furnace ArcelorMittal in Belgium

The raw materials used in the blast furnace, coke and sinter, are loaded into the blast furnace via weighing hoppers. At the bottom of the blast furnace, hot air with a temperature of 1.000° C to 1.200° C is blown into the oven. The hot air reacts with the coke and pulverised coal and forms a reduction gas that abstracts the oxygen from the iron ore. At the same time, heat is created which

Why Use Coke for Blast Furnace Ironmaking not

In blast furnace ironmaking coal is not as strong as coke, and crushing will cause a decrease in the permeability of the blast furnace. The calorific value and carbon content of some anthracite coals are higher than coke, but there are more harmful impurities such as phosphorus and sulfur in coal.

Blast furnace Wikipedia

Within a few years of the introduction, hot blast was developed to the point where fuel consumption was cut by one-third using coke or two-thirds using coal, while furnace capacity was also significantly increased. Within a few decades, the practice was to have a "stove" as large as the furnace next to it into which the waste gas (containing CO) from the furnace was directed and burnt. The resultant heat was used to preheat the air blown into the furnace.

Impact of PCI Coal Quality on Blast Furnace Operations

The injection of coal into the blast furnace has been shown to: 1) Increase the productivity of the blast furnace, i.e. the amount of hot metal produced per day by the blast furnace; 2) Reduce the consumption of the more expensive coking coals by replacing coke with cheaper soft coking or thermal coals; 3) Assist in maintaining furnace stability;
