buried remains of plants pressurized & heated
coal mostly C, some H2O, Hg and S (incorps as forms)
Peat-> Lignite-> Bituminous->Anthracite (add heat + pressure)
-
In what orders are coal formed?
Peat-> Lignite-> Bituminous->Anthracite
(Please Love Big Apples)
-
brown coal
low heat
limited supplies
lignite coal
-
soft coal
commonly used most
high heat content
large supplies
bituminous coal
-
hard coal
high heat content
longest to form
fewer supplies, expensive low sulphur
anthracite
-
coal pros
easy to transport and safe
when burned, releases much energy
abundant & cheap
-
coal cons
