Lower and Higher Heating Values of Fuels

Notes The lower heating value also known as net calorific value of a fuel is defined as the amount of heat released by combusting a specified quantity initially at 25 C and returning the temperature of the combustion products to 150 C which assumes the latent heat of vaporization of water in the reaction products is not recovered
