What type of combustion involves burning all the fuel using only the theoretical amount of air?

The type of combustion that involves burning all the fuel using only the theoretical amount of air is referred to as perfect combustion. In this process, the fuel reacts completely with oxygen, producing only carbon dioxide and water as byproducts. Perfect combustion indicates that there are no unburned fuel or excess air, which signifies that the combustion is highly efficient, maximizing energy output while minimizing pollutants.

Understanding perfect combustion is critical in stationary engineering as it directly impacts the efficiency of energy production and environmental compliance. Sufficient oxygen is essential to ensure complete fuel usage without excess waste or emissions, contrasting with other types of combustion that either leave unburned fuel or involve surplus air.
