Fuel Oil Nozzles

The frequency of nozzle inspection and replacement depends largely on your boiler’s duty cycle, fuel quality, and operational environment. As a general rule for industrial applications, oil nozzles should be inspected during every scheduled maintenance turnaround to check for signs of wear, erosion, or blockage. In environments with high-cycle usage or where fuel cleanliness varies, more frequent inspections are recommended. If you observe poor flame stability, evidence of smoke or soot on the boiler tubes, or a drop in combustion efficiency, the nozzle should be checked immediately and replaced if the precision tip is compromised, as attempting to clean a worn nozzle rarely restores it to original performance specifications.
