That version of the story goes something like this: On July 1, 1937, Amelia Earhart and her navigator Fred Noonan departed from Lae, New Guinea in Earhartâs Lockheed Electra 10, on what was to be the longest portion of Earhartâs highly publicized round-the-world flight.
The youngest coal is not even coal yet -- peat. Peat is a traditional fuel in parts of the world, like Ireland, where it is cut from the earth, dried, and burned for heat. The energy content of peat is quite low. Young coal is called lignite, and is soft and brown, not much different than dried peat.
Firstly coal is converted to lump coke in a coking oven. A particular rank of coal, known as âcoking coalâ, is required to make the preferred quality of coke. Then raw iron is made by reducing (removing the oxygen from) iron ore (iron oxide) by reacting it at high temperature with coke in a blast furnace.
