Bituminous coal classification

Bituminous coal is a type of sedimentary rock used primarily for energy and steel production, and it is classified based on its carbon content, energy value, and sulfur content. It falls into various subcategories, such as high-volatile, semi-volatile, and low-volatile bituminous, which reflect how easily it burns and its quality. Higher-ranked bituminous coal has more carbon, burns cleaner, and generates more heat, making it more valuable. The classification helps determine its best uses and how environmentally friendly it is during combustion.
