What are the three essential components required for combustion?

The three essential components required for combustion are fuel, oxygen, and heat.

Fuel is the substance that burns, providing the necessary energy for the combustion process. This could include natural gas, propane, or other combustible materials. Oxygen is crucial as it supports the chemical reaction of combustion. In most combustion processes, this oxygen comes from the air, which is typically about 21% oxygen. Heat is necessary to initiate and sustain the reaction; it raises the temperature of the fuel and oxygen to the point where they can react with each other.

Together, these three elements create the ideal environment for combustion to occur, leading to the production of heat and light, as well as byproducts such as carbon dioxide and water vapor. Understanding these components is fundamental in various applications, including the operation and maintenance of gas appliances in commercial kitchens.

Other options include terms that do not collectively represent the essential elements for combustion. For instance, light and pressure are not fundamental to the combustion process itself, while nitrogen is typically not involved in the combustion reaction despite being present in the atmosphere.
