In the context of wildland fire, flaming combustion of the gaseous vapors is produced from the heating of solid fuel (generally composed of lignin and cellulose). Flaming combustion is identified by the emission of energy by the ash and soot particles in the fire plume in the visible portion of the electromagnetic spectrum.  The emitted energy is visible only when the ash and soot particles are at a temperature above 977 F. Thus the tip of the flame is defined as the location where the particles in the plume have cooled to 977 F or lower.
