No. 5 fuel oil is also called Navy Special Fuel Oil (NSFO) or just navy special; No. 5 or 6 are also commonly called heavy fuel oil (HFO) or 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. Bunkers are rarely labeled this way in ...
The liquid stored in the tank (no. 6 fuel oil, also known as residual fuel oil or bunker C) is non-flammable, as its flash point is 71°C, well above ambient temperature. However, in the conditions in which it was stored on that day, it became flammable, although the mechanism by which this occurred is not fully confirmed.
The gel point of petroleum products is the temperature at which the liquids gel so they no longer flow by gravity or can be pumped through fuel lines. This phenomenon happens when the petroleum product reaches a low enough temperature to precipitate interlinked paraffin wax crystals throughout the fluid .
Both CII and CCAI are calculated from the density and kinematic viscosity of the fuel. CII was developed by BP to calculate the autoignition capacity of heavy fuel oils (HFO). It is calculated using the measured kinematic viscosity V (cSt or mm 2 /s) of a given fuel determined at temperature t (°C) and the density ρ 15 at 15°C (kg/m 3). [1]
Data available until 2011 for fuel oil sales to the international marine shipping sector reports 207.5 million tonnes total fuel oil sales with HFO accounting for 177.9 million tonnes. [9] Marine vessels can use a variety of different fuels for the purpose of propulsion, which are divided into two broad categories: residual oils or distillates.
Newfoundland and Labrador Hydro's Holyrood Thermal Generating Station burns No. 6 heavy fuel oil at the rate of approximately 6,000 barrels (950 m 3) per day, per unit at full load to produce steam at 1000 degrees Fahrenheit (540 degrees Celsius) and 13,790 kPa at a rate of over 500 megagrams per hour. In an average year it puts out pollution ...

#2 Heating oil price, 1986–2022 Kerosene inventory stock levels (United States), 1993–2022. Heating oil is known in the United States as No. 2 heating oil. In the U.S., it must conform to ASTM standard D396. Diesel and kerosene, while often confused as being similar or identical, must each conform to their respective ASTM standards. [3]
