What is the purpose of the settling tank in a fuel system and what happens in the tank?
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.
Which is higher in maximum temperature Liquid or Gas fuel?
Gas fuel typically has a higher maximum temperature compared to liquid fuel, as gas can combust more efficiently and at higher temperatures than liquid fuel. This is why gas is often preferred in high-temperature applications such as metalworking or welding.
What is the hottest temperature that jet fuel burns?
Jet fuel typically burns at a maximum temperature of around 980°C (1800°F) when ignited under optimal conditions.
What is ignition point of heavy fuel oil?
The ignition point of heavy fuel oil typically ranges from 365°C to 400°C. This is the temperature at which the oil will start to combust in the presence of an ignition source.
What Thermodynamic state function measures the maximum electric work in a fuel cell?
Gibbs free energy is the thermodynamic state function that measures the maximum electrical work that can be obtained from a fuel cell at constant temperature and pressure. It represents the balance between the system's enthalpy, entropy, and temperature.
When was Heavy Fuel created?
Heavy Fuel was created in 1991.
How heavy is Boeing 787?
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).
What is the density of heavy fuel oil bunker?
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.
Vicosity increases as temperature increases?
"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.
What is critical pressure of Heavy fuel oil?
Why did you capitalize "heavy"
What is the temperature of a fuel when its start to burn?
The temperature at which a fuel starts to burn is known as its ignition temperature, which varies depending on the type of fuel. Ignition temperature is the minimum temperature required to initiate the combustion process in a fuel.
How many gallons of heavy fuel oil are in a metric ton?
About 317 gallons of heavy fuel oil are in a metric ton.
