Intermediate Fuel Oil

Intermediate Fuel Oil (IFO) is a type of fuel oil that falls under the supply class of Fuel Oils in the supply group of Fuels, Lubricants, Oils, and Waxes. It is commonly used as a marine fuel for large ships and vessels.

IFO is a heavy, viscous liquid that is derived from crude oil through a refining process. It is typically used in marine engines due to its high energy content and ability to provide efficient combustion. IFO is graded according to its viscosity, with higher numbers indicating a thicker and more viscous oil.

The use of IFO as a marine fuel is regulated by international standards, such as the International Maritime Organization's (IMO) regulations on sulfur content. These regulations aim to reduce air pollution from ships by limiting the amount of sulfur emitted from their exhaust gases. As a result, there are different grades of IFO available, with varying sulfur content to comply with these regulations.

In addition to its use as a marine fuel, IFO can also be used in power generation, industrial boilers, and other applications that require a heavy fuel oil. It is important to note that IFO may require preheating before use to ensure proper combustion and prevent damage to the engine or equipment.

Overall, Intermediate Fuel Oil is a significant component of the Fuel Oils supply class in the Fuels, Lubricants, Oils, and Waxes supply group, primarily used as a marine fuel for large ships and vessels.
