The percentages of these different gases vary depending on where the natural gas comes from. Oxygen = 20% The heating value of a fuel is the heat of combustion (i.e., heat released during combustion) at the reference temperature, T ref = 25C, assuming complete combustion. It also contains hydrogen sulfide and helium in a very little amount. We can plug those numbers into this formula to calculate the LHV: HHV, or higher heating value, refers to the amount of heat released when a fuel is burned completely and the resulting gases are allowed to cool to room temperature. Other factors that can affect a fuels heating value include its moisture content and ash content. The calorific value of a fuel is the amount of heat that is released when the fuel is burned.
