Any fuel that is to be used in any combustion process first, be checked by its calorific values. The cost of fuel is also affected by the calorific value of the fuel. Here you can find the basic information about the calorific value and its type.
Combustion is defined as a sequence of exothermic reactions/operations which at the end give off heat as energy and by-products of combustion products.
e.g. combustion of methane with oxygen gives water and carbon dioxide with energy.
Calorific Value of the fuel
Calorific Value (C.V) or Heating Value or Energy Value is defined as the amount of energy liberated by the complete combustion of the unit quantity of fuel.
- Unit of Calorific Value: Joule per kg (J/kg)
- Calorific Value is a characteristic of fuel, based on this number, a fuel is selected for a particular application and price is also decided based on CV.
1. Higher or Gross Calorific Value (HCV)
1. Lower or Net Calorific Value (LCV)
If water vapor as the product of combustion is not condensed in water form, the net energy obtained by the complete combustion of a unit quantity of fuel is called lower calorific or net calorific value.
For practical purposes, LCV is used in consideration.
