Anthracite is also known as Hard Coal because it is hard and has a shiny, black appearance.
Among the four types of coal – Anthracite, Bituminous, Sub-bituminous and Lignite – Anthracite is ranked the highest type of coal because it has a high carbon content, low moisture content and cleaner burning properties. It also commands a premium because not only is it a superior type of coal but it is also less abundant than other types of coal. Only a handful of countries around the world have Anthracite coal minesand coal production of Anthracite is relatively limited.
Let’s explore the unique characteristics of Anthracite.
High Carbon Content
The carbon content in Anthracite ranges from 86 to 97%, making it one of the purest forms of coal. Its high carbon content means that Anthracite has a high energy density, making it an excellent source of energy.
Low Moisture Content
The moisture content is generally less than 5% which is why it burns with little smoke even as its high carbon content produces a high heat output.
Low Sulfur Content
Anthracite is characterized by low sulfur content. This means reduced emission of sulfur dioxide when burned compared to other types of coal.
High Energy Content
Anthracite easily has the highest energy content among all types of coal because of its high carbon content and low impurities. It provides a very high amount of heat energy when burned, which is why is it ideal for myriad heating and industrial applications.
Ideal for Heating
Clean-burning properties and high energy density means that Anthracite is preferred for residential and commercial, especially in stoves and furnaces. It produces a steady, consistent heat while leaving minimal ash residue.
Metallurgical Use
Anthracite is widely used in the production of iron and steel and serves as source of high-purity carbon in steel manufacturing.
Anthracite is a premium, high-quality coal valued for its high energy content and relatively-low environmental impact when burned.
