- Melting of the fuel
- Transport of the fuel by the capillary action of the wick
- Conversion of the liquid fuel into gas
- Thermal decomposition (pyrolysis) of the fuel
- Oxidation of the pyrolysis products
Solid carbon particles, soot, form at about 1,000 °C. These are excellent blackbody radiators of colors in the yellow to red spectrum. The typical yellow color of a candle flame or wood fire is therefore produced primarily by the hot soot. The mixing of the fuel and the O2 is the slowest part of the combustion process and, therefore, the rate determining step.
