Want this question answered?
Ship fuel is not fed straight into the main engine, as first of all the HFO (Heavy Fuel Oil) is pumped and then separated into a settling tank (buffer tank). The settling tank is connected to the service tank (day tank). This service tank is filled via a continuous overflow from the settling tank and is also connected with the main engine. The oil is heated in both the settling and service tank to make sure that an even temperature of between +75°C and +90°C (or +167°F and +194°F) is maintained, as this keeps the heavy fuel oil (HFO) at a consistency that can be pumped easily.
Depending on how high the pressure is, they both can have the same maximum temperature. After a while, they become a different type of phase called a supercritical fluid.
Heavy Fuel was created in 1991.
Between a minimum of 250,000 pounds (no fuel, seats, food, people, etc) and 500,000 pounds (maximum takeoff weight, full fuel, people, seats, luggage, etc).
Construction grade steel burns at 2795 degrees Fahrenheit. Jet fuel does not burn this hot. Its maximum temperature is 1472 degrees Fahrenheit.
In a technical sense, any fuel used by ships is bunker fuel. As regards heavy fuel oil, it's either No. 5 or No. 6 fuel oil, and is most commonly No. 6 or "bunker fuel" or "navy special fuel oil" or something similar.No. 6 heavy fuel oil has a specific gravity of about 0.94 to 0.95 at room temperature (68 degrees F), and that translates to a weight density of about 59.3 to 59.9 pounds per cubic foot. Water weighs 62.44 pounds per cubic foot, by comparison at 68 degrees F.
Heavy fuel oil (aka No. 6 Fuel Oil) is used by furnaces, boilers, fired heaters, and large engines on tanker ships. It must be preheated to about 150°F before it can be pumped due to its high viscosity at room temperature. In coal-fired power plants No. 6 heavy fuel oil is sometimes used to start up the boiler, then the power source is later switched to coal.
"Viscosity" is basically a resistance to flow. Viscosity is inversly proportional to Temperature. For example, high viscous heavy fuel is heated to right temperature to lower its viscosity for proper combustion in diesel engines or boiler.
Why did you capitalize "heavy"
is on the fuel pump inside of the fuel tank,,,,,,......if you lookin for the fuel temperature sending unit.
heard of fatty acids in palm oil but not in marine heavy fuel.
