What ignites the secondary and tertiary nozzles in a multi-burner cluster?

In a multi-burner cluster, the primary burner is specifically designed to provide the initial ignition source for the entire system. The primary burner typically operates before the secondary and tertiary burners come online, ensuring a proper ignition sequence. When the primary burner is lit, its flame provides the heat necessary to ignite the secondary and tertiary nozzles.

The secondary and tertiary burners may have separate ignition systems; however, they rely on the stable flame produced by the primary burner to effectively ignite. In multi-burner setups, maintaining the right sequence and timing is crucial for safety and efficiency in combustion processes. The primary burner's flame helps to establish a stable environment needed for the secondary and tertiary burners to function properly once they are activated.
