- The nozzle atomising holes should be inspected for signs of enlargement which can lead to improper fuel atomisation and bad combustion. Presence of cat fines in fuels will accelerate the wear of the nozzle holes.
- The swirler plate should be inspected for erosion corrosion. The swirler plate converts pressure energy to velocity and increases the speed of the oil flow to give the required atomisation, turbulence & penetration
- The ignition electrodes’ clearances are critical for flame establishment during start-up and should be set as manufacturers’ recommendation.
4. The ignition electrodes’ tips should not be worn, carbonised or pitted.
5. The ceramic isolator body in the ignition electrodes should not be cracked or broken to prevent current leakage
6. The air swirler vanes should not be dirty/carbonised
7. Photocell checked for cleanliness
8. Filters in pump and burner checked for cleanliness
