Kromschroder Ignition electrode ZKIH L400 74450303

The Kromschroder ZKIH L400 ignition electrode (SKU 74450303) is a 400 mm long spark ignition electrode designed for use with Kromschroder ZKIH series pilot burners. It is made from a heat-resistant special alloy (Kanthal A1) and is resistant to soot. This electrode provides direct electrical ignition for the pilot burner in industrial gas burners, boilers, furnaces, and dryers. It is a 100% original Kromschröder spare part, manufactured in Germany.

When selecting an ignition electrode of this type, verify that the electrode length, bend geometry, insulator diameter, spark gap, and mounting flange arrangement match the burner design. Measure the existing electrode's dimensions and compare them with the replacement part before ordering. Ensure the ceramic insulator is clean and uncracked, and that the gap between the electrode tip and the burner body or ground electrode is consistent. Confirm the mounting interface is compatible with the burner being serviced.

Common failure modes for ignition electrodes include erosion of the electrode tip, cracking of the ceramic insulator, and sooting or carbon deposits on the insulator. These issues can cause a drifting spark gap, leading to longer ignition times or burner lockout. The equipment may fail to ignite or shut down unexpectedly. Check the electrode for visible damage, clean any deposits, and verify the spark gap is within specification.
