Classification of Coal based on Carbon Content
Coal is classified according to its carbon content because it is the main component that determines the quality and energy content of coal.
Types of Coal based on Carbon Content
- Peat: The lowest rank of coal with the least carbon content.
- Lignite: Also known as brown coal, it has a higher carbon content than peat but lower than other types of coal.
- Sub-bituminous: This type of coal has a higher carbon content than lignite but lower than bituminous coal.
- Bituminous: One of the most commonly used types of coal, bituminous coal has a higher carbon content compared to sub-bituminous coal.
- Anthracite: The highest rank of coal with the highest carbon content and energy content.
Significance of Carbon Content
The carbon content of coal determines its energy content, burning characteristics, and uses. Higher carbon content in coal results in a higher energy content and better combustion efficiency. Therefore, coal with higher carbon content, such as anthracite, is more desirable for applications where high heat output is required, like in industrial processes or electricity generation.
In summary, coal is classified based on its carbon content because it directly influences its quality, energy content, and potential uses. Understanding the carbon content of coal helps in selecting the most suitable type for specific applications.
