- Abstract
- Many fire-spread situations involve the following basic burning processes: Reflexive heat from the hot flame is transferredc to the unburned fuel bed. When an unburned fuel-surface element becomes sufficiently hot, additional heat vaporizes it. The resulting gaseous fuel reacts upon coming into contact with the oxygen supplied by the air flowing into the flame zone. Some of the released chemical energy is transferred to the unburned fuel bed, thus completing the energy cycle necessary to maintain the fire-spread processes.
