Web2 days ago · The lower calorific value of a substance can also be known as the lower heating value and the fuel's net calorific value. It can be determined by subtracting the latent heat value of water vaporization formed in the reaction from the gross calorific value (which is the higher heating value). WebFor the heat of combustion, it is generally expressed in units of higher heating value, lower heating value, and gross heating value.
