WebFireline intensity is synonymous with the terms “Byram's fire intensity” (Byram 1959) and “frontal fire intensity.” It is the numerical product of a fire's rate of spread, fuel consumption, and heat yield at a given point on a fire’s perimeter. Reaction intensity and total fire flux are examples of other measures of fire intensity. Units WebDec 1, 2016 · The intensity per unit length expressed by Byram's formula (1) is derived from the heat released from the unit length perimeter of the front. This energy depends on the front width, its perimeter, the fuel load and the heat of combustion.
