What is the difference between combustion and fire?
Combustion is the underlying chemical reaction in which a substance combines with oxygen to release heat and light, while fire is the visible, physical result of that reaction. Every fire involves combustion, but combustion can also occur without visible flame, as in slow oxidation.
What are the different types of combustion?
Combustion is generally described as complete, where a substance burns fully with plenty of oxygen and produces mainly carbon dioxide and water, or incomplete, where limited oxygen leads to byproducts like carbon monoxide and soot. Engineers and scientists also distinguish rapid combustion, such as an explosion, from slow combustion, such as rusting.
What is needed for combustion to occur?
Combustion requires a fuel, an oxidizer (usually oxygen), and enough heat to start the reaction, a combination often called the fire triangle. Remove any one of these three elements and the combustion process stops.
