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.

∙ 14y agoThe waste gases are carbon dioxide and nitrogen. They come out at the top of the furnace. The carbon dioxide is from the reduction reaction. The nitrogen is from the air blast. It has taken part in the reactions so has not been changed.

∙ 14y agoThe coke we put in blast furnaces to produce iron is almost all carbon. Some ash will be present, and a bit of sulfur, tar and some other residues of the coking process. But carbon is what we're looking for to react with the iron oxide and reduce it to iron in the blast furnace. Use the link below to check facts and learn more.

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 black pipe used for?
I assume you mean black iron pipe, which is used to run the gas line to your furnace.
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.
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.
Uses of waste gas in blast furnace?
none
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 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.
Why does natural gas furnace have water waste?
It is not waste. The furnace has extracted the majority of the heat through the combustion process to the point of "condensation". Condensation= H2O. lc
What is a gas furnace and its advantage?
A gas furnace is a furnace that operates to keep your house warm with the use of gas. Gas furnaces are very energy efficient furnaces, and are the most common furnaces used in North America.
How do you identify an electric furnace from a gas furnace?
an electric furnace runs off of 208/230 Volts while a typical gas furnace runs off of 120 also a gas furnace will have a valve for the gas relay where the gas enters the furnace.
