Answer 2

Anthracite is the most superior variety of coal.

• The rank of a coal depends upon the percentage of carbon present in its composition.

• Anthracite has the highest carbon content of 85 - 95 %, among all varieties of coal.

• It has a sulphur content of less than 1 % and a mositure content lower than 15 % . Hence, it produces an insignificant amount of fly ash and almost no smoke while burning.

• Anthracite produces the maximum amount of heat, among all varieties of coal, during combustion.

• Anthracite is also the hardest type of coal known.
