Boiler House Automation Retrofit
Ammonia/hydrazine auto-dosing replaced manual work; boiler pH stays compliant.
Key Metric
0
Manual dosing
Challenge
Manual timed dosing let feedwater pH and dissolved oxygen drift, raising corrosion risk.
Solution
Ammonia and hydrazine dosed proportionally to feedwater flow with online sample feedback.
Results
- Zero manual dosing
- Long-term pH compliance
- Clearly lower corrosion rate
