What is defined as tertiary air in the combustion process?

Tertiary air in the combustion process refers to the air that ensures all oil is burned completely. This air plays a crucial role in achieving complete combustion by supplying the necessary oxygen to burn any remaining fuel that may not have ignited during the initial combustion stages. This not only enhances the efficiency of the combustion process but also minimizes harmful emissions, improving the overall environmental impact of the heating system.

In the context of oil heating, achieving thorough combustion is vital to prevent issues such as soot buildup, which can lead to reduced efficiency and potential system failures. By ensuring that all oil is completely burned, tertiary air contributes significantly to the performance and effectiveness of an oil burner.
