HFO = Heavy Fuel Oil 380 CST = the grade of fuel oil representing viscosity, quality, etc.
No, water does not burn. Blending it would reduce the effectiveness of the fuel oil as a fuel.
dilution will reduce the viscosity The effect of dilution on viscosity of oil is that it will decrease.
light crude oil has less specific gravity,less viscosity while heavy crude oil has more specific gravity & viscosity.
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.
IFO 380 - Intermediate fuel oil with a maximum viscosity of 380 CentistokesIFO 180 - Intermediate fuel oil with a maximum viscosity of 180 Centistokes
The viscosity depends on the chemical composition of materials.
Please see the link in the related links section. Please note that actual viscosity of No. 6 fuel oil depends on the actual blend of products and the product specifications of the fuel oil. Fuel oils are usually classified by viscosity and sulfur. In particular more stringent sulfur specifications require more light products (light cycle oil (LCO) or unconverted oil (UCO)) to be blended into No. 6 fuel oil. This results in a less viscous fuel oil. There is no universal standard specification for No. 6 fuel oil.
This situation presents an direct relationship between the oil viscosity and the work of the pump. The thicker the oil the more the pump most work to move it.
Many ships use MDO or Marine Diesel Oil, sometimes also known as #2 Diesel. Ships can also use HFO or Heavy Fuel Oil or Bunker C. These are crude oil derivatives that are largely unrefined. They are very thick and need to be heated by steam in order to reduce its viscosity to allow them to flow.
The viscosity of the oil may not be heavy enough to protect the engine.
