Properties of Heavy Fuel OilProperties of Heavy Fuel Oil

Rather than typical values, HFO properties have to achieve maxima

values principally for :

other properties (needed for the purchaser)

density

viscosity (cSt) @ 50C or 100C

flash point

sulfur content

pour point ash, asphaltene, vanadium, aluminium content
