Anthracite Coal is more normally known as "hard coal". Anthracite coal is a highly-carbonated fossil fuel that will generate the highest heat of all the fossil fuels available, and the low sulfur content in Anthracite makes it an extremely clean-burning fuel. New technology and engineering design changes to burners have made it even easier to use.

Uses of Coal. Description. Power Generation. Steam coal, also known as thermal coal, provides a source of electricity. Power plants ground steam coal into a powder and fire it into a boiler to produce heat. The heat is used to turn water into steam. The steam powers a turbine that, along with an alternator, generates electricity.

As you can see, while there once may have been clear advantages to coal, they pale in comparison to the flexibility and renew-ability of burning wood in modern times. Not only do you have these added effects, but the devastation caused by accidental fires in a forest is far less severe than a coal fire.

The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time. Anthracite contains 86%-97% carbon and generally has the highest heating value of all ranks of coal.
