Flame Safeguard Controls - Fireye

2018-4-4 · A flame is a zone within which the combus-tion reaction occurs at a rate that produces visi-ble radiation. A flame front is the contour along which the combustion starts — the dividing line between the fuel-air mixture and the combus-tion process. In stable flames, the flame front appears to be stationary. The flame moves
