What is the function of air in the blast furnace?
to burn coke that will burn the raw material
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.
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.
Oversize Quartzite effect on Blast Furnace coke rate?
to reduce basicity
Which three substances are put into the blast furnace?
Limestone, Iron Ore and Coke.
Why is coke and not coal added to the blast furnace?
Coke contains more carbon than coal and hence coke produces more heat
What are the three substances fed into the blast furnace?
Carbon rich coke limestone and iron
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 goes into a blast furnace?
Sinter, which is a mixture of iron ore, coke and limestone, and a blast of hot air. Externally to the furnace, iron ore, coke and limestone are mixed together Intimate mixing ensures that the reactants are as close as possible to each other. This is loaded into the top of the blast furnace. A blast of hot air ( ~ 1100 oC) is sent in at the bottom of the furnace, through tuyeres. The oxygen (air) is also one of the reactants. The products are tapped from the bottom of the furb=nace are liquid iron and 'slag' ( calcium silicate).
