Massachusetts Oil Burner License Practice Test

Which component is key in ensuring the ignition sequence in an oil burner?

1. Transformer

2. Pump

3. Fan

4. Ignition electrode

The correct answer is: Transformer

The transformer is a key component in ensuring the ignition sequence in an oil burner because it is responsible for converting standard electrical voltage into a higher voltage required for ignition. When the burner is activated, the transformer generates the spark needed to initiate combustion by creating a high-voltage arc at the ignition electrode. This ensures that the oil mist is ignited promptly and efficiently, allowing for a smooth startup of the burner process. While the other components, such as the pump, fan, and ignition electrode, play significant roles in the functioning of the system, they do not directly initiate the ignition sequence. The pump delivers the fuel oil to the burner, the fan provides the necessary airflow for combustion, and the ignition electrode produces the actual spark; however, without the transformer supplying the high voltage, the ignition sequence could not occur effectively. Hence, the transformer is crucial for starting the ignition process in an oil burner.
