Kromschroder Pilot burner ZKIH500/100R 84214050

The Kromschroder ZKIH500/100R pilot burner (SKU 84214050) is a German-made component designed for ignition and flame monitoring of main burners in industrial boilers and thermal installations. It features a 500 mm protective tube and a 100 mm flame tube, with an internal Rp threaded connection. The burner operates with a permanent or intermittent pilot flame and includes an ionization electrode for flame monitoring. It is suitable for use with natural gas, LPG, or town gas, providing a thermal output range of 2-7 kW (up to 5 kW with natural gas).

When selecting a replacement pilot burner of this type, verify the electrode length and bend, insulator diameter, spark gap, and mounting flange pattern to match the existing assembly. The burner series and the specific model for which the assembly was designed must be confirmed. Installation involves connecting via the internal Rp thread and ensuring proper sealing between the burner and mounting plate. Always compare the physical dimensions and configuration of the old part before ordering.

Typical failure modes for pilot burners of this kind include erosion of the ignition electrode tip, cracked ceramic insulation, sooting that short-circuits the ionization signal, and a drifting spark gap that lengthens ignition time. These issues can cause unreliable ignition or loss of flame signal, leading to burner shutdown. During servicing, check the condition of both electrodes and the seal between the burner and mounting plate, as leaks can destabilize the pilot flame.
