Kromschroder Pilot burner ZAI K 84228010

The Kromschroder ZAI K pilot burner (SKU 84228010) is a gas-fired ignition burner with ionization control, designed for permanent or intermittent operation. It carries a small flame that ignites the main burner and provides a flame signal for the burner control. The power requirement for this pilot burner is 2-5% of the main burner power. It is suitable for natural gas, coke oven gas, town gas, and liquefied gas, and can be used as a standalone burner. The assembly integrates the burner body, gas nozzle, and electrodes for ignition and flame detection via an ionisation electrode.

When selecting a replacement pilot burner of this type, key parameters to match include gas type, gas pressure and flow rate, physical mounting arrangement, and flame shape. The flame detection method must be compatible with the existing burner control—for an ionisation electrode, the pilot flame must conduct a rectified current, and the electrode tip must be positioned correctly within the flame zone. Verify the exact dimensions, thread size, and electrode geometry against the original part. The gap between the electrode and the burner body should be set according to the manufacturer's specification for ignition.

A worn pilot burner of this type can cause delayed ignition, flame lockout, or intermittent flame failure. Inspect the electrode condition for eroded tips, cracked ceramic insulators, or heavy sooting, which indicate the pilot burner has reached its service life. Ensure the gas supply line is clean and the gas pressure matches the burner datasheet. It is advisable to replace the pilot burner proactively during a burner service.
