Coal has been used for many decades as a major source of energy across the world. It has helped to power industries, households, and transportation systems, making it one of the most valuable resources on the planet. However, most people hardly know anything about it. If you’re curious about the different types of coal that exist in the world, then this article is for you.
The Different types of Coal: Overview
Coal exists in several different forms, but the most commonly known types are anthracite, bituminous, and lignite. These various forms of coal are created through different processes and are used for different purposes.
Anthracite
Anthracite is the highest-ranking coal in the world. It’s also the hardest and densest of them all, and its high carbon content means it burns hotter and longer than any other type of coal. It contains about 86% to 97% carbon and has a blueish-black color. Anthracite is mainly used for heating and in the manufacture of coke, which is used to make steel.
Bituminous
Bituminous coal is the most widely used type of coal across the globe. It has a carbon content that ranges from 45% to 86%, and it’s further divided into two subcategories: thermal coal and metallurgical coal. Thermal coal is primarily used in generating electricity, while metallurgical coal is used in the steel-making process.
Lignite
Lignite is the lowest-ranking type of coal. It is also the youngest and softest of all types, with a carbon content between 25% to 35%. Lignite is found in extensive quantities worldwide but is mainly harvested in Germany, Greece, and Turkey. It’s primarily used for generating electricity.
Conclusion
Now that you have a basic understanding of the different types of coal, you’ll be able to appreciate this valuable resource better. Anthracite, bituminous, and lignite coal all play important roles in our daily lives, powering everything from our homes to our industries. By knowing how coal works and its different types, you’ll be better equipped to understand how it fits into our energy needs now and in the future.
