Higher heating value definition

WebThe high heating value includes this energy. The lower calorific value doesn’t include the energy released in condensing water. This is why a gross calorific value is higher than a net calorific value. HHV = water vapour is condensed = more heat is recovered LHV = water vapour remains as vapour – less heat is recovered WebHigh Heating Value or HHV means the amount of heat released by a specified quantity of fuel once it is combusted and the products have returned to at the same temperature, which takes into account the latent heat of vaporization of water in the combustion products.
