Lower heating value — The lower heating value (also known as net calorific value , net CV , or LHV ) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25 °C or another reference state) and returning the temperature of … Wikipedia
Higher Heating Value — (HHV) The maximum heating value of a fuel sample, which includes the calorific value of the fuel (bone dry) and the latent heat of vaporization of the water in the fuel. (See moisture content and net (lower) heating value, below.) … Energy terms
