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

How much coal coke is needed to run a blast furnace for one day?
that would depend on the size of the blast furnace.
What is the word equation for coke in a 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)
How is slag collected from a blast furnace?
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.
What is used in the furnace to extract the iron?
blast furnace
How burden calculated in blast furnace?
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.
What is the function of air in the blast furnace?
to burn coke that will burn the raw material
How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
What is coke for in a blast furnace?
the Coke supplies carbon monoxide to reduce the ore in a blast furnace and supplies heat to melt the iron.
How much coal coke is needed to run a blast furnace for one day?
that would depend on the size of the blast furnace.
How much coke required for production of one ton hot metal in blast furnace?
The amount of coke required for the production of one ton of hot metal in a blast furnace can vary, but on average, it takes about 800-1000 kilograms of coke per ton of hot metal. Coke is used as a fuel and reducing agent in the blast furnace to help convert iron ore into molten iron.
Oversize Quartzite effect on Blast Furnace coke rate?
to reduce basicity
Why is coke and not coal added to the blast furnace?
Coke is added to the blast furnace instead of coal because coke is a purified form of coal that has higher carbon content and produces less impurities when burned. This helps maintain the purity of the iron being produced in the blast furnace. Additionally, coke generates higher temperatures, promoting better efficiency in the iron-making process.
Why is hot air blasted into a blast furnace?
Hot air is blasted into the blast furnace to burn the coke (a cheap form of carbon) added to form carbon dioxide.
What is the function of tuyeres in blast furnace?
to let air out
What is the difference between blast furnace coke and cupola coke?
Mainly the type of coke being used. The sulfur, ash and carbon content are different.
How nut coke is charged in blast furnace?
According to steel.nic.in; Coke Rate is measured in Kgs of BF Coke consumed per tonne of Hot Metal produced in the Blast Furnace(Kg/THM). By convention, this excludes coke (nut/pearl coke) mixed with sinter etc. Introduction of high quality coke to a blast furnace will result in lower coke rate, higher productivity and lower hot metal cost. This principal is followed by many private chemical firms like Coke Oven Consultants and so on.
What substance are mixed with iron ore in the blast furnace?
Coke (a form of carbon) and limestone are mixed with iron ore in the blast furnace. Coke provides the heat source for the chemical reaction, while limestone helps to remove impurities from the iron ore.
