The visible, gaseous portion of a fire is called a flame (from the Latin flamma). It is brought on by a chemical reaction that occurs in a narrow zone and is very exothermic. Flames are said to as plasma when they are hot enough to include sufficiently dense ionized gaseous components.

When a lighter is held to a candle, for example, the color and temperature of the flame depend on the type of fuel being burned. The fuel molecules in the candle wax evaporate as a result of the heat being delivered (if this process happens in inert atmosphere without oxidizer, it is called pyrolysis). They may then easily interact with the oxygen in the air in this condition, releasing enough heat in the next exothermic process to evaporate additional fuel and maintain a steady flame.

The vaporized fuel molecules disintegrate at a high temperature in the flame, producing a variety of incomplete combustion products and free radicals. These products then interact with one another and the oxidizer in the subsequent flame to produce further reactions (fire). A cold metal spoon may be used to examine every component of a candle’s flame: Combustion produces water vapor, which is found higher up; soot, which is yellow in the middle; and unburned wax, which is found lower down right near to the candle wick.


For melting gold and silver, goldsmiths employ higher sections of a flame and a metal blowpipe. Some temporary chemical intermediates, such as the methylidyne radical (CH) and diatomic carbon (C2), will have their electrons excited by enough energy in the flame to cause visible light to be released as these molecules release their surplus energy (see spectrum below for an explanation of which specific radical species produce which specific colors). If a flame contains small amounts of unburned carbon or other material, the combustion temperature of the flame will rise along with the average energy of the electromagnetic radiation the flame emits.

To create a flame, oxidizers other than oxygen can be utilized. The combustion of hydrogen in chlorine results in a flame and the release of gaseous hydrogen chloride (HCl) as a byproduct. Another of the numerous conceivable chemical mixtures is the hypergolic mixture of hydrazine and nitrogen tetroxide, which is frequently employed in rocket engines. Fluorine can be provided by fluoropolymers to oxidize metallic fuels, such as magnesium, teflon, and viton.

The chemical dynamics that take place in the flame are extremely complicated and frequently include many chemical reactions and intermediate species, the majority of which are radicals. For instance, the combustion of biogas is described using 53 species and 325 fundamental processes using the well-known chemical kinetics model GRI-Mech.

The necessary components of combustion can be delivered to a flame through a variety of techniques. The flame starts when the oxygen and fuel flow into one another in a diffusion flame. Premixed flames produce a different kind of flame since the oxygen and fuel are combined in advance. Candle flames (a diffusion flame) burn by the fuel being evaporated, which rises in a laminar flow of hot gas that then combines with the oxygen in the air and combusts.
