theory of combustion

The theory of combustion involves a chemical reaction where a fuel (like wood or gasoline) reacts with oxygen from the air, producing heat, light, carbon dioxide, and water. This process requires three components: fuel, oxygen, and an ignition source—known as the fire triangle. When these elements come together with enough energy input, the fuel breaks down and reacts rapidly with oxygen, releasing energy in the form of heat and flames. Combustion can be complete or incomplete, depending on how much oxygen is available, affecting the amount of emissions produced.
