Furnace Fuel Oil

04 September 2012

  furnace fuel oil (FFO); The high viscosity requires heating, usually by a recirculated low pressure steam system, before the oil can be pumped from a bunker tank. In the context of shipping, the labeling of bunkers as previously described is rarely used in modern practice. Since the 1980s the International Organization for Standardization (ISO) […]

Number 6 fuel oil

04 September 2012

Number 6 fuel oil is a high-viscosity residual oil requiring preheating to 220 – 260 °F (104 – 127 °C). Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities including 2 percent water and one-half percent mineral soil. This fuel may […]

Fuel Oil and Combustion Values

04 September 2012

The heating or combustion value of a fuel can be expressed as the quantity of heat (Btu per gallon) released during the combustion process where oxygen from the air reacts with the hydrogen and carbon in the fuel. The combustion or heating value for some common fuels oil grades are indicated in the table below: […]

Density Of Furnace Oil

01 September 2012

The density is also an important parameter for fuel oils since marine fuels are purified before use to remove water and dirt from the oil. Since the purifiers use centrifugal force, the oil must have a density which is sufficiently different from water. Older purifiers had a maximum of 991 kg/m3; with modern purifiers it […]
