Blast Furnace: Introduction, Definition, Construction, Working ...

Introduction. A blast furnace is a special type of cylindrical furnace, which is basically used for the purpose of smelting. So, the industrial metals can be extracted from their ores like iron, pig iron, or copper. The word 'blast' gives the idea of combustion air which is forcefully supplied or produced to the atmospheric pressure above.

How is coal formed? - Coal Education

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants - giant ferns, reeds and mosses - grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.
