The Fire Triangle
Three things necessary to start and maintain a fire are fuel, oxygen, and heat
Oxygen in the air supplies the fire
As the fire eats up the oxygen in the air, it heats it up making it rise and a new supply of cooler air replaces it
Just like all reactions, fire need a certain amount of activation energy to get started. Once started, the reaction supplies the necessary energy for the reaction to continue
A fire must have some kind of fuel to continue.
