Which component regulates the flow of oil in the burner?

The component that regulates the flow of oil in the burner is the fuel valve. The fuel valve is primarily responsible for controlling the amount of fuel delivered to the burner based on the system’s demand for heat. It opens and closes in response to signals from the burner controls, allowing the appropriate amount of oil to flow to ensure efficient combustion.

In the context of an oil heating system, the fuel valve operates to maintain the correct mixture of fuel and air and ensures that the burner operates safely. This regulation is crucial for the efficient performance of the heating system, as it affects the size of the flame and the overall efficiency of the combustion process.

The fuel pump, while essential for delivering oil from the tank to the burner, does not regulate the flow itself but rather provides the necessary pressure to move the fuel. The oil filter is designed to remove contaminants from the oil before it reaches the burner, protecting the system but not regulating flow. The thermostat controls the temperature of the heating system, which indirectly affects how much oil is needed, but it does not directly regulate the flow of oil in the burner.
