What is one source of air that aids in atomization in an oil burner?

In the context of an oil burner, secondary air plays a crucial role in the atomization process. This type of air is introduced after the initial atomization has occurred, and its purpose is to facilitate complete combustion by mixing with the fuel spray. The secondary air helps achieve a more efficient and thorough mix of fuel and air, which is essential for optimal combustion performance.

Atomization refers to breaking the liquid fuel into small droplets to enhance its mixing with air for combustion. While primary air is essential for initial combustion and can aid in mechanical atomization, secondary air is uniquely positioned to assist in ensuring that the flame is stable and that the entire mixture combusts effectively. Thus, identifying secondary air as a source of air that aids in atomization correctly reflects its role in the operation of oil burners, where effective combustion and fuel efficiency are paramount.
