Kromschroder Electrode rod BR100 L135 74330322

Kromschroder Electrode rod BR100 L135 (SKU 74330322) is an ignition or ionization electrode for Kromschroder BR 100 industrial gas burners. It has an electrode length of 135 mm and is made of special heat-resistant alloy Kanthal A1, providing high heat resistance and resistance to soot. The rod is designed for stable ignition and flame control in high-temperature combustion environments. It is a consumable part that must be replaced periodically to maintain burner performance.

Parts of this type are selected by required length, bend, insulator diameter, spark gap, and mounting flange pattern, all of which must match the burner or pilot burner head geometry. Before ordering, verify the exact dimensions against the original part, as the reference code indicates a specific rod length and bend profile. During installation, inspect the mounting bracket, reset the electrode gap to the manufacturer's specification, and ensure the high-tension lead and boot are not tracking to ground. The pilot burner, if used, must be clean and correctly positioned relative to the electrode.

Common failure modes include erosion of the tip from repeated sparking, cracking of the ceramic insulator due to thermal shock, sooting that bridges the gap, and gradual drift in the electrode gap that lengthens ignition time. When these occur, the burner may fail to ignite, experience delayed ignition, or lose flame signal, leading to burner lockout. Check the electrode tip for wear, the insulator for cracks, and the gap for proper spacing, and clean or replace as needed.
