Reference Answer
### (a) Maintenance Required on an Auxiliary Boiler Burner (8 Marks)
As a Chief Engineer, ensuring the reliable and safe operation of the auxiliary boiler is paramount. This requires a systematic and thorough maintenance schedule for the burner assembly. Maintenance can be categorized into routine checks (daily/weekly) and periodic overhauls (monthly/annually or as per PMS).
**1. Burner Nozzle / Atomiser Assembly:**
* **Cleaning & Inspection:** The nozzle/atomizer is critical for correct fuel spray pattern and combustion. It should be regularly removed and cleaned. Check for clogging of orifices, which leads to poor atomization and flame impingement. Use soft tools (brass brush, compressed air) to avoid damaging the precision-drilled holes.
