Depending on their intended application, fuel oils are liquid mixtures made from crude petroleum ranging from yellow to light brown. They are usually combustible and smell like paraffin. 

What are the Uses of Fuel Oil?

Here are the uses of fuel oil –

  • Heating: Both domestic and commercial boilers use lighter fuel oils, such as No. 1 and No. 2.
  • Power generation: In boilers, heavier fuel oils, such as No. 5 and No. 6, are burned to produce electricity.
  • Marine transportation: Many boats and ships run on marine petrol oil (MGO).
  • Industrial processes: various industrial applications can be served by fuel oils in boilers and furnaces.

Q1. Does diesel differ from fuel oil?

Ans. Diesel fuel and fuel oil are nearly identical. The only difference is their usage. 

Q2. What does petroleum-based fuel consist of?

Ans. Petroleum-based fuel is composed primarily of a mixture of methane series petroleum hydrocarbons, with an average of ten to sixteen carbon atoms per molecule (HSDB 1991; IARC 1989). 

Q3. What are the Types of Fuel Oil?

  • Distilled Fuels: lighter and cleaner products from the initial stages of the process. 
  • Residual Fuel Oil: Heavy and more viscous fuels that remain after lighter components are eliminated are called residual fuels.
