n. Net caloric content of wildland fuel after reductions for moisture content and water of reaction.
Byram (1959) calculated heat yield as the high heat of combustion minus losses resulting from radiation, incomplete combustion, water of reaction, and fuel moisture. A standard value of 1263 kJ/kg of fuel is assumed for estimating the heat loss associated with the latent heat of vaporization of the water of reaction of wildland fuels (Byram 1959).
Radiation is arguably not a loss of heat at all and should not be removed from high heat of combustion. Losses due to incomplete combustion are variable and difficult to measure (Alexander 1982).
