What characterizes an interrupted ignition system?

An interrupted ignition system is characterized by the spark being activated only briefly at startup and then turning off once the flame is established. This method is designed to ensure that the ignition system provides a spark just long enough to ignite the fuel-air mixture, after which the flame sensor or monitoring system confirms that combustion has started successfully. Once the flame is detected, maintaining the spark is unnecessary, as the ignition process has been successfully initiated.

This type of system is efficient in preventing continuous spark generation, which could lead to excessive wear or energy consumption. By only providing the spark during the critical moments of ignition, the system optimizes both safety and performance, allowing for a smooth transition to normal operation where the flame sustains itself.
