Continuously flowing mixture of hot gases with a stationary position that derives its heat content from a strongly exothermic, irreversible chemical reaction between a fuel and an oxidant.
Note:
The flame in general consists of a primary-combustion zone, a secondary-combustion zone and an interconal zone.

| Term | Definition | Note |
|---|---|---|
| fuel | Reducing agent that reacts with oxidant to provide the energy necessary for atomization and excitation. | |
| laminar flame | Flame for which the gas flow rate is sufficiently low such that the incoming gaseous flow of fuel and air is laminar, as is the flame. | The cross-section of the flame can have any shape. |
| oxidant | Oxidizing agent that reacts with the fuel providing the energy necessary for atomization and excitation. | |
| oxidzing flame | Flame obtained using an excess of oxidant. | |
| reducing flame | Flame obtained using an excess of fuel. | |
| separated flame | Flame in which the secondary-combustion zone is separated from the primary-combustion zone. | |
| turbulent flame | Flame in which the burnt-gas flows in an irregular pattern. |
