Subbituminous Coal

Subbituminous coal is a type of coal that falls under the supply class of Fuels, Solid in the supply group of Fuels, Lubricants, Oils, and Waxes. It is a low-rank coal that is intermediate in properties between lignite and bituminous coal.

Subbituminous coal has a lower carbon content and higher moisture content compared to bituminous coal. It is typically brown to black in color and has a relatively low energy content. However, it still serves as an important source of fuel for power generation and industrial processes.

Due to its lower carbon content, subbituminous coal produces less carbon dioxide emissions when burned compared to higher-rank coals. It is also more abundant and widely available, making it an attractive option for energy production in certain regions.

In terms of usage, subbituminous coal is commonly used in power plants to generate electricity. It is also used in industrial processes such as cement production and steel manufacturing. Additionally, it can be used for residential heating and as a fuel source in some commercial applications.

Overall, subbituminous coal plays a significant role in the global energy mix, providing a relatively affordable and accessible source of fuel for various applications.
