In the context of oil burners, what does a 'booster pump' primarily assist with?

A booster pump in the context of oil burners primarily assists in maintaining fuel pressure. This is crucial for the efficient operation of the burner, as a consistent and adequate fuel pressure ensures that the oil is delivered at the right rate to the burner nozzle. Proper fuel pressure is necessary for achieving the desired atomization of the fuel, which contributes to effective combustion. When fuel pressure is stable, the burner can operate efficiently, minimizing the risk of incomplete combustion, smoke production, or other operational issues.

Maintaining the right fuel pressure is vital because fluctuations can lead to performance problems, such as poor ignition or uneven burning. Therefore, a booster pump serves as an essential component in creating a reliable and stable environment for oil burners to function properly, enhancing overall heating efficiency and safety.
