Bunker C

Bunker C is a heavy, fuel oil used primarily in industrial applications like power plants and ships. It is a thick, viscous liquid with a high energy content, requiring heating to flow easily. Because it produces more pollutants and is less refined than lighter fuels, Bunker C has become less common with environmental regulations. It was historically used where low cost was more important than ease of handling, but nowadays, cleaner alternatives are preferred due to its environmental impact.
