Calorific Value (CV) is a measure of heating power and is dependent upon the composition of the gas. The CV refers to the amount of energy released when a known volume of gas is completely combusted under specified conditions.

Calorific value is defined as the amount of heat energy produced on complete combustion of 1 kilogram of a fuel. It is expressed in a unit called kilojoule per kg. The higher the calorific value of a fuel, the more is its efficiency. Table below shows calorific value of different fuels:      Fuel   Calorific value Hydrogen     150000 LPG      55000 CNG      50000 Methane      50000 Petrol      45000 Kerosene      45000 Diesel      45000 Biogas      40000 Coal      33000 Wood      22000 Cow dung      8000 Each kilogram of LPG produces much more heat than one kilogram of wood or coal. The calorific value of LPG is the highest among wood, charcoal and LPG. In rural areas, cow dung and wood are still used as fuel because these are very cheap and easily available.
