The Blast Furnace

The Blast Furnace

 
In at the top goes limestone, iron ore, coke
limestone=calcium carbonate
iron ore=iron oxide
coke=carbon

Hot air is pumped in the furnace at the bottom.

Then at the end of the furncae **** and molton iron come out of it.

The Blast Furnace

500 degrees

Then 500 degrees is near the top of the furnace. At 500 degrees Carbon Monoxide takes oxygen from the ore to leave iron.

word equation
iron oxide+ carbon monoxide -> iron+ carbon dioxide

symbol equation
Fe2O3+ 3CO -> 2Fe+3Co2

The Blast Furnace

1000 degrees

This is in the middle of the furnace. Here carbon dioxide is converted to carbon monoxide.

word equation
carbon dioxide+ carbon -> carbon monoxide

symbol equation
Co2+C -> 2CO

The Blast Furnace

1500 degrees

This is near the bottom of the furnace. Here carbon dioxide is made.

word equation
carbon+oxygen -> carbon dioxide

symbol equation
C+O2 -> Co2
