Where is the retention ring mounted on an adjustable head oil burner?

The retention ring is a crucial component of an adjustable head oil burner, and its primary purpose is to ensure that the combustion process is efficient and effective. It is mounted on the nozzle assembly, where it plays a vital role in controlling the fuel-air mixture that enters the combustion chamber.

When located on the nozzle assembly, the retention ring helps to maintain a proper flame stability and influences the combustion efficiency. It aids in preventing the flame from lifting off the nozzle when the burner is in operation, ensuring adequate heat is produced during the burning of oil. This positioning of the retention ring optimizes the burner’s performance, minimizes emissions, and improves overall system efficiency.

Understanding this function is essential for maintaining and troubleshooting oil burners, as any issues with the retention ring's placement or condition can lead to inefficient burning and increased emissions.
