Fuel is an explosive substance containing carbon as the main constituent, which on proper burning gives a large amount of heat, which can be used economically for domestic and industrial purposes. E.g., Wood, Charcoal, Coal, Kerosene, Petrol, Producer gas, Oil gas, LPG, etc.
The major composition of all fuels is carbon and hydrocarbons, so they are also called hydrocarbons.
During the process of combustion of a fuel (like coal), the atoms of carbon, hydrogen, etc., combine with oxygen with the simultaneous liberation of heat at a rapid rate.
Fuel + Oxygen → Products + Heat

Major Constituents of Fuel
Fuel is a substance that is burned to produce energy. The major constituents of fuel are carbon and hydrogen, which are the primary elements that contribute to the energy content of the fuel.

Explanation
- Carbon: Carbon is a key component of fuel, providing the primary source of energy when burned. It is found in various forms in fuels such as coal, oil, and natural gas.
- Hydrogen: Hydrogen is another important constituent of fuel, as it reacts with oxygen during combustion to release energy. It is found in fuels like gasoline, diesel, and natural gas.
- Oxygen, Nitrogen, Phosphorus, and Sulphur: While oxygen, nitrogen, phosphorus, and sulfur can be present in small amounts in some fuels, they are not considered major constituents of fuel. These elements may contribute to the overall composition of the fuel but do not play a significant role in its energy content.
Therefore, the major constituents of fuel are carbon and hydrogen, which are responsible for the energy generation when the fuel is burned.
