What is the density of heavy fuel oil?
HFO is characterized by a maximum density of 1010 kg/m3 at 15°C, and a maximum viscosity of 700 mm2/s (cSt) at 50°C according to ISO 8217.
Is fuel oil more viscous than petrol?
Another key property of a bigger hydrocarbon is that it will have a higher viscosity. So, gasoline is less viscous than kerosene. And kerosene is less viscous than diesel. This means our answer is C.
Where is heavy fuel oil used?
It is used for the large ship engines of cargo vessels, bulk carriers of industrial or mining products like iron ore, cruise ships, and even the engine fuel for large oil tankers (though the oil that large oil tankers carry is called Crude Oil that has not yet been refined and is lighter than Heavy Fuel Oil).
Why do ships use heavy fuel oil?
Sludge formation: A ship needs to carry heavy fuel oil in abundance to ensure a continuous supply of fuel to engines and boilers during the long voyage. The heavy fuel oil is stored in the ship’s bunker tanks.
What is viscosity of kerosene?
Kerosene. 1.92 x 10–3. 2.39 x 10–4.
Why is viscosity important in fuel?
Viscosity is one of the most important factors which directly affects combustion quality. A high viscosity fuel oil leads to improper atomisation which in turn leads to incomplete combustion. High viscosity fuel prevents correct atomisation,which takes place in the fuel injectors.
Does gasoline have a high viscosity?
The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
Why is IMO 2020?
The new regulations, known as IMO 2020, mandates a maximum sulphur content of 0.5% in marine fuels globally. The driver of this change is the need to reduce the air pollution created in the shipping industry by reducing the Sulphur content of the fuels that ships use.
What fuel do large ships use?
Large commercial vessels, such as cargo ships, generally operate on HFO while smaller ships, such as tugs and fishing vessels, tend to operate on distillate fuels, such as marine diesel oil (MDO), marine gas oil (MGO), or even ultra-low sulfur diesel fuel (ULSD).
What is DMA fuel?
DMA (also called marine gas oil, MGO) is a general purpose marine distillate that must be free from traces of residual fuel. This contamination with residual fuel usually occurs in the distribution process, when using the same supply means (e.g., pipelines, supply vessels) that are used for residual fuel.
What Colour is fuel oil?
What colour is gas oil? Gas oil contains a red dye that can be easily traced (hence the name red diesel) to help the police and DVSA identify illegal usage. Road diesel is not dyed, which is why it’s sometimes called white diesel.
Why is bitumen not used as fuel?
Bitumen itself is a black and very sticky liquid. It’s also highly viscous and so full of carbon that it cannot be used for combustion (unlike gasoline, diesel and jet fuel).
Which fuel is the most viscous?
Diesel fuel no. 4 is also called marine diesel fuel. It is the most viscous of the diesel fuels and contains higher levels of ash and sulfur.
