Heavy Fuel Oil

Heavy Fuel Oil

This kind of fuel can significantly affect at performance, operation and maintenance of fuel engine. To better understand the important effect of this fuel on the engine itself, it is important to have a basic understanding of fuel characteristic properties and contaminants which impact the operation of engine and fuel treatment system.

Where as the fuel engine is a very efficient power plant it does have a higher degree of sensitivity to specific fuel properties and contaminants. High important characteristic properties are included, viscosity , sp.gr , Carbon Residue , Ash and Sediment contents , compatibility , flash point, p.p, water and Solphur content which are tested along with some contaminants like sodium aluminum, silicon, chloride, vanadium, zinc and some others.
