What is the primary role of secondary air in oil combustion?

The primary role of secondary air in oil combustion is to complete the combustion process. When oil is burned, the initial mix of fuel and air may not always be ideal for complete combustion, leading to incomplete burning and the production of pollutants such as carbon monoxide and unburned hydrocarbons. Secondary air is introduced to provide additional oxygen, which allows for more thorough mixing and promotes the continued oxidation of the fuel. This enhances combustion efficiency, reduces emissions, and maximizes energy output.

The importance of completing combustion cannot be overstated, as it directly affects both the performance of the heating system and the environmental impact. Efficient combustion leads to higher temperatures and better energy use while minimizing harmful emissions, making the role of secondary air critical in achieving an effective and environmentally responsible combustion process.
