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)
What is the function of coke in a blast furnace?
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.
What three materials are used in a blast furnance?
The three materials typically used in a blast furnace are iron ore (mainly hematite or magnetite), coke (a form of carbon derived from coal), and limestone (as a flux to help separate impurities from the molten iron).
The purpose of adding coke to the iron ore in a blast furnace is?
COKE acts as a reducing agent. It combines with oxygen to form CO which in turn reacts with iron ore to give metallic Iron. Carbon present in coke also produces heat in all oxidation reactions which melts down the metallic iron.LIMESTONE (CaCO3) breaks down to CaO upon heating which reacts with SiO2, the main impurity, to flux it out of the furnacebasically, the limestone is there to remove acidic impurities
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.
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 the coal unsuitable for charging directly in the blast furnace?
Coal is unsuitable for charging directly into a blast furnace because it contains impurities like sulfur and ash that can negatively affect the quality of the iron produced. When coal is used as a fuel in the blast furnace, it can lead to increased levels of impurities in the iron, affecting its properties. As a result, coke, which is a cleaner form of coal, is typically used in blast furnaces for iron production.
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.
What is the charge in the blast furnace?
The charge in the blast furnace typically consists of iron ore, coke (a form of coal), and limestone. The iron ore is the main source of iron, the coke provides the heat and reducing agent, while the limestone helps remove impurities in the form of slag.
What are the three substances fed into the blast furnace?
The three substances fed into the blast furnace are iron ore (in the form of sinter, pellets, or lumps), coke (a form of carbon derived from coal), and limestone (which helps remove impurities from the iron ore and acts as a flux).
How does the blast furnace maintain the heat?
The blast furnace maintains heat through the combustion of coke (a type of coal) with hot air blown in at the bottom. This creates a high temperature that allows the iron ore to melt and collect at the bottom of the furnace. The heat is further sustained by the chemical reactions occurring within the furnace.
Where does the carbon that is used in blast furnace come from?
Coal, distilled to drive off itscontents and leave the carbon, plus a little bit of non-volatile impurities, principally silica; in a form called Coke. (No relation to the colloquialcontraction of Coca-Cola! :-) )
What goes into a blast furnace?
A blast furnace typically contains iron ore, coke (fuel derived from coal), and limestone. These materials are layered in the furnace and hot air is blown in at the bottom to create a chemical reaction that produces molten iron.
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
What is the function of air in the blast furnace?
to burn coke that will burn the raw material
