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 function of septum valves in blast furnace?
Septum Valves are installed after the dust collector venturi scrubber , to decrease the pressure of Top gas from the blast furnace to supply it to other processes at low pressure.
What is the material in gas pipes of a belt continuous furnace?
The gas pipes of a belt continuous furnace are typically made of stainless steel or copper.
How blast furnace productivity has been improved?
1. By increasing size and improving design. 2. By injecting hydrocarbons (the C in these means less coke is needed so there's more space in the shaft for the ore) 3. Enriching the blast air with pure O2 (this increases the flame temperature where the air gets heated and it increases the production of CO.) 4. Higher pressure at the top of the blast furnace (it increases the flow rate of the gas without increasing its velocity) and 5. By changing the physical and chemical properties of the raw materials.
Will a furnace leak gas if a basement floods?
Probably not, but if the furnace or a part of it was submerged you should have it checked out.
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.
Uses of waste gas in blast furnace?
none
What is the waste gas produced in the blast furnace?
The waste gas produced in the blast furnace is primarily carbon dioxide (CO2) along with other gases such as carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen oxides (NOx).
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
Blast furnace gas calorific value?
Blast furnace calorific value is 780 Kcal/hr
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 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
Why sinter is used in blast furnace?
Sintering has two reasons: 1- You want to put in the blast furnace an homogeneous mix of flux and mineral. 2- You want something with a lot of pores. So the reductor gas can make contact with a lot of surface.
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 function of septum valves in blast furnace?
Septum Valves are installed after the dust collector venturi scrubber , to decrease the pressure of Top gas from the blast furnace to supply it to other processes at low pressure.
