Kromschroder Ionization and ignition electrode FZE600 74434614

The Kromschroder FZE600 74434614 is an ionization and ignition electrode in the Kromschroder electrode range. It has an electrode length of 600 mm and is resistant to soot. Electrodes of this type either deliver a high-voltage spark from the ignition transformer to light the fuel-air mixture or prove the flame by passing a small rectified current through it, which the burner control detects as a flame signal. The electrode sits in the flame zone and is a consumable item subject to thermal and electrical stress. Some burners combine ignition and ionization functions in one electrode, while others use separate electrodes for spark and flame sensing.

Parts of this type are selected by matching the electrode length and bend, the insulator diameter, the spark gap or rod geometry, and the mounting flange arrangement to the burner series or combustion head. The electrode shape must place the tip correctly in the flame. Before ordering, measure the existing electrode and compare its geometry and mounting with the replacement. When fitting, inspect the ceramic for hairline cracks and clean any soot from the insulator, and check the connection cable and the high-voltage lead from the transformer for insulation damage.

Electrodes of this kind commonly fail through eroded or pitted tips, cracks in the ceramic insulator, sooting or carbon deposits that short the spark, and a drifting gap that delays or prevents ignition. On the equipment this appears as failed or delayed ignition, a missing or unstable flame signal, or repeated lockouts. Check the electrode tip, the ceramic insulator, the spark gap, and the high-voltage lead for damage or deposits.
