Which component is critical in determining the combustion process of oil burners?

The fuel nozzle plays a crucial role in the combustion process of oil burners because it is responsible for atomizing the oil into a fine mist, which is essential for efficient combustion. This atomization allows the oil to mix thoroughly with air, enabling a proper and effective combustion reaction. The design and condition of the fuel nozzle directly affect the spray pattern, droplet size, and the overall mixture of fuel and air entering the combustion chamber.

If the fuel nozzle is clogged or not functioning properly, it can lead to incomplete combustion, resulting in reduced efficiency, increased emissions, and potential damage to the burner equipment. Therefore, maintaining the correct fuel nozzle type for the given burner system and ensuring it is in good condition are critical for achieving optimal combustion performance.
