Kromschroder Isolated electrode FZE700 74434615

Kromschroder Isolated electrode FZE700 74434615 is an ionization and ignition electrode with a length of 700 mm. It is designed for use in industrial gas burners, providing spark ignition and flame monitoring. The electrode features high heat resistance and is resistant to soot accumulation. Its ceramic insulator is prone to cracking, which is a known characteristic of this component.

When selecting a replacement electrode of this type, ensure the overall length, bend angle, insulator diameter, and spark gap match the original specifications. The mounting flange pattern must align with the burner or pilot burner body. Check the insulator for hairline cracks and confirm the gap using a gauge. If the burner manual specifies, renew the sealing gasket or o-ring during installation.

Common failure modes include erosion of the tip, cracking of the ceramic insulator, carbon sooting that bridges the gap, and a drifted gap. These issues can lead to ignition problems, false flame control alarms, emergency equipment shutdowns, and excessive fuel consumption. Inspect the insulator for cracks and verify the gap is within specification.
