Which device provides a 14,000-volt spark to ignite the oil?

• A. Electronic ignitor spark generator
• B. Ignition transformer
• C. Pilot burner
• D. Spark plug

Answer: (A)

Oil burner ignition relies on delivering a high-voltage spark to ignite the atomized fuel-air mixture. The electronic ignitor spark generator is designed to produce a brief, powerful spark—typically around 14,000 volts—at the exact moment the burner control opens the fuel path and starts the ignition sequence. This solid-state device charges and discharges to create the spark reliably in the burner’s harsh environment, ensuring ignition occurs promptly and consistently. An ignition transformer serves a similar purpose in older systems by stepping up line voltage to a high voltage for a spark gap, but it’s less common in modern equipment and doesn’t inherently handle modern control and flame-sensing features. A pilot burner simply provides a flame to light the main burner; it does not generate a spark. A spark plug would generate a spark in other engines, but oil burners use a dedicated spark generator rather than a spark plug.
