Boiler Water Treatment Dosing Essentials
Summary: Roles and dosing control of ammonia, hydrazine and phosphate, with automated dosing system design.
Three Core Chemicals
- Ammonia: raises feedwater pH against acid corrosion
- Hydrazine: chemical deaeration against oxygen attack
- Phosphate: internal softening against calcium scale
Control
Dose proportionally to flow or load, guided by online sampling, keeping each parameter in range.
Automation
Metering pumps + online analyzers + PLC deliver unattended operation with alarms. See the boiler solution.
