What are the three types of coal used for?

Thermal coal is mostly used for power generation cement manufacturing and other industrial purposes while metallurgical coal is used primarily for manufacturing iron and steel. Anthracite is the most mature coal and thus has the highest carbon content of any type of coal.

What are the different kinds of coal?

Coal is classified into four main types or ranks: anthracite bituminous subbituminous and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.

What is class 3 coal?

Why are there different types of coal?

Coal is made up mainly of carbon along with differing quantities of other elements chiefly hydrogen with smaller quantities of sulphur oxygen and nitrogen. Older coal generally has higher carbon content. Younger coals have a lower carbon and calorific content the fuel is dirtier and the moisture higher.

Which type of coal is the rarest?


Anthracite – Anthracite contains 86-97 percent carbon but has a slightly lower heating value than does bituminous coal. It is rare in the U.S. (all known anthracite deposits are located in Pennsylvania) and only represents less than half of one percent of total U.S. coal production.

What is the difference between anthracite and bituminous coal?

Explanation: Anthracite coal is a higher grade than bituminous coal and is formed under greater pressure and at higher temperatures. Anthracite coal contains more carbon than bituminous coal and less sulfur making it more desirable. Bituminous coal also contains more moisture than anthracite coal.

Why is anthracite The best type of coal?

It has the highest carbon content the fewest impurities and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism) in which the carbon content is between 86% and 98%.
