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.
