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

The retention ring is mounted on the nozzle assembly of an adjustable head oil burner, contributing to the efficiency and performance of the burner. This component is designed to create a specific turbulence and pattern in the oil mist, allowing for better combustion by ensuring that the oil is adequately mixed with air before it ignites. The positioning on the nozzle assembly is critical because it directly influences the spray pattern and droplet size of the fuel delivered to the combustion chamber.

Properly setting the retention ring allows for optimal combustion characteristics and helps reduce emissions, ensuring a cleaner burn. It also plays a role in preventing flame blow-off and backfire by stabilizing the flame. Placement in other components like the fuel tank, burner head, or flue pipe would not provide the same effect and could lead to inefficient operation or safety issues.
