What does interrupted ignition mean?

Interrupted ignition refers to a system where the ignition spark is activated for a limited duration to ignite the oil mist produced upon startup, then it is turned off after a brief period. This process is essential for the efficient and safe operation of oil burners. The spark ignites the fuel-air mixture only when needed, preventing prolonged combustion attempts that could lead to excess fuel buildup or other issues.

This method is designed to enhance safety by reducing the potential for flammable vapors accumulating in the combustion chamber. By having the ignition spark turn off after the initial phase, the system minimizes risks and improves efficiency in the overall combustion process. Understanding this concept is critical for technicians working with oil heating systems, as it impacts both functionality and safety measures in installation and maintenance practices.
