Brahma Electrode BR89 C00620156

This ignition electrode is designed to create a spark in burner ignition systems. It features ceramic insulation for high-temperature protection. The electrode length is 185 mm, width is 40 mm, depth is 16 mm, and net weight is 3.9e-05 kg. It is intended for use in gas and oil burners.

For ignition electrodes of this kind, key selection parameters include overall length, bend angle of the rod, diameter of the ceramic insulator, spark gap, and mounting flange pattern, which must match the original burner series. The electrode is mounted in the flame zone, and its position relative to the burner head determines the spark gap. Before ordering, measure the old part’s geometry and compare it with the replacement. During installation, remove the old electrode without damaging the ceramic and verify that the new one matches the original geometry.

Typical failure modes include erosion of the electrode tip, cracking of the ceramic due to thermal shock, carbon sooting that bridges the spark gap, and a gap that drifts out of tolerance as the metal wears. These conditions can cause delayed ignition or loss of flame signal, leading to burner lockout. Check the ceramic for cracks, the tip for erosion, and the spark gap for proper clearance.
