Why is iron from the blast furnace hard and brittle?
Due to the high carbon.
Which is the finest iron ore with a very high content of iron up to 70 percent?
hematite with 66% iron in it. In olden days haematite is directly fed into the blast furnace
Why you used carbon refractory at blast furnace?
You don't. Carbon burns! The fuel is carbon (as coke). The refractory lining (fire-bricks) is made from minerals with very high melting-points.
How are metals separated from ores?
smelting is used for sulfide ores. Iron ores require a blast furnace. aluminum ores require high temperature electrolysis. etc. it varies by type of ore and metal.
What are refractory materials?
They are materials , usually bricks, made with silicon oxides, that will withstand extremely high heat, without decomposition or chemical reaction. e.g. Blast Furnaces are internally lined with refactory bricks to with stand tha 1100 oC temperature of the furnace. The metal shell/chassis of the furnace would melt. Outside these refractory bricks is a water jacket to prevent heat escaping, into the outside environment.
Why the height of blast furnace is 100ft?
the height of blast furnace is kept high to ensure the completion of reaction.
How High Is A Blast Furnace?
1650 Celsius
Why is iron from the blast furnace hard and brittle?
Due to the high carbon.
Do a heating furnace use gas coal wood or fuel to work?
yes heating furnace use coal and wood to heat and work.Because you cannot get such high temperature without that .
What is a high efficiency furnace I should look into buying in order to keep my 5000 square foot home warm?
a high efficiency furnace is a furnace that uses less electicity and saves on heating expences. they are very useful in the winter and great to lower your central heating bills.
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 type of appliances use ally have high power rating?
Appliances for heating purpose have high power ratings.
Which is the finest iron ore with a very high content of iron up to 70 percent?
hematite with 66% iron in it. In olden days haematite is directly fed into the blast furnace
Where can one purchase a high efficiency furnace?
Try heating and air conditioning shops or full-service plumbing shops. If you look in the Yellow Pages of your phone book under 'Heating contractors' or 'Heating Equipment', you should see some shops near you listed.
Why you used carbon refractory at blast furnace?
You don't. Carbon burns! The fuel is carbon (as coke). The refractory lining (fire-bricks) is made from minerals with very high melting-points.
What increases the utility bill the most fan heaters or central heating?
It depends on what type of central heating unit that you have. An electric furnace will drive the electrical utility bill very high. If it is a natural gas furnace, not a very high electrical demand just for the blower fan. A heat pump demand is just above a gas furnace but more efficient. Heat pumps usually have electric heating as a back up for the very cold days. Fan heaters are usually rated about 1500 watts and are a little inefficient to heat large rooms. They will probably be on more that they will be off.
How are metals separated from ores?
smelting is used for sulfide ores. Iron ores require a blast furnace. aluminum ores require high temperature electrolysis. etc. it varies by type of ore and metal.
