How and why things burn
|Fire:||the next three components form the fire triangle and are all necessary to sustain a fire|
|Heat:||an energy source is necessary to ignite the sample (initiate burning) and sufficient energy must be produced by the flame to continue burning|
|Fuel:||sample must produce fuel vapors (this may involve simple vaporization or thermal decomposition of the sample)|
|Oxygen:||oxygen must mix with the fuel vapors and reaction will occur with sufficient energy (the chemical reaction is a complex mechanism that involves radicals)|
|Products:||the combustion products are a mixture of hot gases and particulate matter that rise from the fire|
Now let's go look at the stages of burning.
