Marine fuel may be obtained from petroleum distillation or either distillate or a residue. In general terms heating oil is any liquid fuel that's burned during a furnace or boiler for the generation of warmth or utilized in an engine for the generation of power, except oils having a flash point of roughly 42 °C (108 °F) and oils burned in cotton or wool-wick burners. Fuel oil is formed of long hydrocarbon chains, particularly alkanes, cycloalkanes, and aromatics. The term heating oil is additionally utilized in a stricter sense to refer only to the heaviest commercial fuel which will be obtained from petroleum , i.e., heavier than gasoline and naphtha. Small molecules like those in propane and naphtha and gasoline for cars and jet fuel have relatively low boiling points and that they are removed at the beginning of the fractionation process. Heavier petroleum products like diesel oil and grease are much less volatile and distill out more slowly, while bunker oil is literally rock b...
