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 ?
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 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.
What uses less gas a furnace or fireplace?
fireplace
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
A condensing gas furnace uses from a condensing type heat exchanger to increase the furnace efficiency?
Yes
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.
