What is the purpose of supplying access air to the burner?

The main purpose of supplying access air to the burner is to ensure there is enough oxygen for complete combustion. In the combustion process, oxygen is essential to enable fuel to burn efficiently and produce energy. When the air-to-fuel ratio is optimized, it allows for a more complete reaction between the fuel and the oxygen, resulting in more efficient energy production and increased burner performance.

When access air is provided, it can help prevent incomplete combustion, which can lead to the production of harmful byproducts such as carbon monoxide or unburned hydrocarbons. Adequate oxygen supply also contributes to stable flame characteristics, reducing the chances of flame instability or sooting, which can occur when there is insufficient air. Therefore, ensuring enough oxygen is critical to maintaining not just efficiency but also safety in the operation of HVAC oil burners.
