Properties of Heavy Fuel Oil (HFO)

The quality of the heavy fuel oil is largely determined by the crude oil grade and the refining process applied. This is the reason why heavy fuel oil of the same viscosity may differ considerably in quality from one bunker place to another. Heavy fuel oil normally is a mixture of residue oils and distillates. The components of the mixture often come from state of the art refining process such as visbreaker of catalytic cracking plant. These process may have a negative effect on the stability of the fuel and on its ignition and combustion properties. In this essence these factors also influence the heavy fuel oil treatment and the operating results of the engine.
