Higher sulfur and nitrogen content compared to anthracite, contributing to acid rain if not treated.

Features high volatile content (up to 46%), which makes it easier to ignite but also produces more smoke and soot than anthracite. Key Applications

Extensively burned in thermal power plants to generate steam.

Significant CO2 producer during combustion.

Widely utilized in cement production and other heavy industrial heat applications. Pros and Cons

Can be "beneficiated" (cleaned) to meet specific industrial standards.

Typically offers energy outputs between 6,642 and 8,355 kcal/kg (approximately 27–35 MJ/kg). Carbon Content: Contains between 40% and 85% carbon .

More efficient than lignite or sub-bituminous coal.
