Why is blast furnace waste gas mainly nitrogen?
Blast furnace waste gas is mainly nitrogen because nitrogen makes up about 78% of the atmosphere and is used as the primary gas for the blast furnace process. During the process, the injected air reacts with the fuel and iron ore to form nitrogen-rich waste gas.
Why is a blast furnace called blast furnace?
how does the blast furnace maintain the heat ?what is the function of CaCO3 ?how the slag protect the molten iron ?why does iron flow down to the bottom /how does the slag and molten iron get seperated ?what is use of waste gas /what is main impurity of iron in blast furnace ?
What is the formula of blast furnace gas calorific value?
The formula to calculate the calorific value of blast furnace gas is: Calorific value (MJ/m³) = 0.313 x %CO + 0.313 x %H2 + 0.093 x %CH4. In this formula, %CO represents the percentage of carbon monoxide, %H2 represents the percentage of hydrogen, and %CH4 represents the percentage of methane in the blast furnace gas.
What is the actual reducing agent of haematite in blast furnace?
The reducing agent for hematite in a blast furnace is carbon monoxide (CO) gas, which is produced by the combustion of coke (carbon) at high temperatures. CO reacts with iron oxide (Fe2O3) to form iron metal and carbon dioxide (CO2) gas. This reduction process is essential for extracting iron from hematite ore.
How is DRI superiour to blast furnace iron?
Direct Reduced Iron (DRI) is considered superior to blast furnace iron because it is produced through a process that involves reducing iron ore without melting it, resulting in a purer form of iron with lower impurities. DRI also has higher iron content and can be produced using natural gas, making it more environmentally friendly compared to blast furnace iron production. Additionally, DRI can be used in electric arc furnaces, providing more flexibility in steelmaking processes.
Uses of waste gas in blast furnace?

Blast furnace gas calorific value?
Blast furnace calorific value is 780 Kcal/hr

What can blast furnace waste slag be used for?
its used a fuel , but has less calorific value as the carbon monoxide percentage is less which is the main combustible gas in the b.f gas. its used in heating the blast of hot air in the blast furnance itself and also can be used in rolling mill, sinter plant, and many more where you need heating
What is made in a blast furnace?
Several things come out of blast furnaces. They are listed here: 1) A molten version of whatever material was put in it to begin with, 2) Incredible heat, 3) Powerfull light, 4) A waste gas and usually some slag remnant of the fuel that powers the furnace.
What is the Color code of Blast Furnace Gas Pipeline?
grey with red stripes
What is dust catcher in blast furnace?
It removes the heavy dust particles coming along with the BF(Blast Furnace) gas by reducing the velocity of the gas so that the dust particles are left as the gas lost it's ability to carry the dust particles
What is the formula of blast furnace gas calorific value?

What is the waste gas in the Blast Furnace used for?
It is mostly carbon monoxide and nitrogen gases which has some heating value. So it is typically recovered and mixed with natural gas, &/or coke oven gas and used in boilers for steam or other steel heating furnaces for further processing of steel.
