Which component helps to regulate the flow of oil to prevent over-pressurization?

The component that helps to regulate the flow of oil and prevent over-pressurization is the back pressure relief. This device is designed to maintain safe pressure levels within the oil delivery system of the burner. It allows excess oil to return to the tank or circulate through the system when pressure exceeds predetermined limits, thus preventing any potential damage to the equipment or safety hazards from occurring due to over-pressurization.

This is particularly critical in oil burner operations, as improper pressure levels can lead to inefficiencies in combustion and increase the risk of safety issues, such as leaks or even system failure. The back pressure relief ensures that the oil flow remains within safe operating parameters, promoting the reliability and safety of the overall oil burning process.

Other components like the atomizer cup, main fuel valve, and oil filter serve different functions within the oil burner system. The atomizer cup is responsible for breaking the oil into fine particles for efficient combustion, the main fuel valve controls the primary flow of oil to the burner, and the oil filter clears any contaminants from the oil before it enters the combustion chamber. While all these components are essential for the proper functioning of the system, it is the back pressure relief that specifically addresses the concern of regulating oil flow to avoid over
