What is the term for the compressed air used as atomizing air in oil burners?

The term "primary air" specifically refers to the compressed air utilized as atomizing air in oil burners. In combustion processes, primary air is mixed with the fuel to facilitate better atomization, which enhances combustion efficiency. The atomization process involves breaking the fuel into fine droplets, allowing for a more effective mix with air, which is crucial for proper combustion.

This primary air is drawn into the burner along with the oil, ensuring that the fuel is dispersed effectively before it enters the combustion chamber. The design of burners often incorporates features that optimize the flow and mixing of primary air and fuel to achieve complete combustion, which can significantly reduce emissions and improve overall efficiency.

Other terms like "combustion air," "pre-mixed air," and "secondary air" have distinct roles in the combustion process. Combustion air refers broadly to all air required for combustion, pre-mixed air is typically associated with air-fuel mixtures that are combined ahead of time, and secondary air is introduced after fuel has been ignited to support combustion and optimize the burning process. Each of these plays an important role, but they do not specifically denote the compressed air used as atomizing air in oil burners as primary air does.
