Why is maintaining an O2 level within the 6-9% range important for combustion?

Maintaining an O2 level within the 6-9% range is vital for ensuring complete combustion because this specific range provides an optimal environment for fuel and oxygen to react fully. When the oxygen level is too low, incomplete combustion occurs, resulting in the production of carbon monoxide and other harmful byproducts, which can pose safety risks. Conversely, if oxygen levels are excessively high, they may lead to wasted fuel and reduced efficiency, as not all the available energy is utilized effectively.

In the context of combustion systems, achieving complete combustion is crucial for not only maximizing energy output but also for minimizing pollutants and enhancing overall system efficiency. Utilizing the correct O2 levels directly influences the combustion process, allowing for a more controlled and efficient operation. This is particularly important in settings where environmental regulations are in place and where maintaining air quality is essential.
