bunker fuel

Bunker fuel is a type of heavy, high-viscosity fuel used primarily to power large ships such as cargo vessels and tankers. It is derived from crude oil during refining and is known for its density and energy content. Because of its thick consistency, bunker fuel requires special boilers to burn efficiently. It is a less refined, cheaper fuel compared to gasoline or diesel, but it produces higher emissions, which has led to international regulations to reduce its environmental impact. Essentially, bunker fuel is the main energy source that keeps large ships operating on long journeys across the oceans.
