What does tertiary air ensure in the burning process?

Tertiary air plays a crucial role in the burning process by ensuring complete combustion of oil. When tertiary air is introduced into the combustion chamber, it helps to provide the necessary oxygen that may not be adequately supplied by primary and secondary air alone. This additional oxygen promotes a more thorough and efficient burning of the oil, minimizing the likelihood of incomplete combustion, which can lead to the production of harmful pollutants and unburned fuel residues.

By optimizing the combustion process, tertiary air allows for a more complete transformation of the fuel into energy, carbon dioxide, and water vapor, thereby improving overall combustion efficiency. This is essential for not only achieving the desired energy output but also for meeting regulatory requirements concerning emissions and environmental impact.
