What generates the over 10,000 volts needed for ignition in an oil burner?

The ignition transformer is responsible for generating over 10,000 volts needed for ignition in an oil burner. This high-voltage output is essential to create a strong enough spark to ignite the oil mist that is produced during the fuel injection process.

The ignition transformer steps up the standard electrical voltage from the power supply to a much higher voltage. This is crucial in ensuring that the spark produced is hot enough and has sufficient energy to overcome the resistance of the air-fuel mixture. Once ignited, the combustion process can commence efficiently, allowing for effective heating without excessive smoke or unburned fuel release.

The other components mentioned do not serve this ignition purpose. A motor powers the burner system but does not produce high voltage. An accumulator, if present, typically stores oil but isn't involved in the ignition process. The combustion chamber is where the burning occurs, but once again, it doesn’t generate voltage; instead, it is the site where the ignition occurs after the spark is produced.
