What we did

- 02Three-element feedwater control (drum level, steam flow, feedwater flow) to prevent carryover and tube burnout.
- 03Inverter-driven forced and induced draft fan modulation with burner safety interlocks.
- 04JSA, method statements and termination diagrams.
The result
The boiler now runs on three-element feedwater control and new burner interlocks. Steam supply to the refinery is secured.
