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.

Why is a blast furnace called blast furnace?
A blast furnace is given its name because it uses a blast of hot air to create high temperatures required for the smelting process. The term "blast" refers to the forced air used to increase the combustion rate and temperature inside the furnace, essential for melting iron ore and producing pig iron.
Which exothermic reaction causes the temperature to rise in the blast furnace in reduction of hematite using coke in the blast furnace?
The exothermic reaction that causes the temperature to rise in the blast furnace during the reduction of hematite using coke is the combustion of carbon (C) in coke with oxygen (O2) to produce carbon dioxide (CO2) and release heat energy. This reaction helps maintain the high temperatures necessary for the reduction of hematite to iron.
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.
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.
How calcium oxide is formed in a blast furnace?
Calcium oxide is formed in a blast furnace as a byproduct of the smelting process when limestone, which contains calcium carbonate, is added to the furnace. The intense heat of the furnace decomposes the calcium carbonate into calcium oxide and carbon dioxide. The calcium oxide is then collected as a solid residue.
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.
Symbol equation for the reaction that provides heat to maintain the temperature of the blast furnace?
The symbol equation for the reaction that provides heat to maintain the temperature of the blast furnace is: C(s) + O2(g) -> CO2(g) This reaction involves carbon (in the form of coke) reacting with oxygen to produce carbon dioxide, releasing heat energy in the process.
What is the Heat loss in blast furnace?
Heat loss in a blast furnace can occur through various mechanisms, such as conduction, convection, and radiation. It is crucial to minimize these losses to ensure efficient operation of the furnace and optimize energy consumption. Various insulation materials and refractories are commonly used to reduce heat loss in blast furnaces.

What is the German word for blast furnace?
Blast furnace = Hochofen
What is Blast Furnace?
A blast furnace is used to extract iron from its ore.
Why blast furnace called as blast furnace?
Its because air is forced into the furnace to increase temperature. Steve.
When was Govăjdia Blast Furnace created?
Govăjdia Blast Furnace was created in 1810.
What Is A Blast Furnace?
A blast furnace is a forge in which ore is smelted to meal, being intensified by a blast of hot air.

How does limestone coke and iron ore get into the blast furnace?
through the top of the blast furnace
