Boiler Scale Inhibitor (Phosphonate + Polymer Blend)
CAS Number: N/A (blend)
Formulated blend of organophosphonates, carboxylic acid polymers, and dispersants for scale prevention in low-pressure and medium-pressure steam boilers up to 40 bar. Controls CaCO₃, CaSO₄, and silica deposition on heat transfer surfaces to maintain boiler efficiency and prevent tube failure.
Technical Specifications
| dosage | 5–20 mg/L to feedwater |
| packaging | 200 kg drum |
| appearance | Clear to yellow liquid |
| formulation | Phosphonate + carboxylic polymer + dispersant |
| scale control | CaCO₃, CaSO₄, silica |
| boiler pressure | LP/MP up to 40 bar |
| pH operating range | 9.5–11.5 (boiler water target) |
Applications
- Low-pressure and medium-pressure steam boilers (up to 40 bar)
- Hot water boiler circuits in district heating systems
- Industrial process steam generation in food, textile, and chemical plants
- Package boiler feedwater treatment
- Waste heat recovery boilers (WHRB)
- Combined heat and power (CHP) boiler water conditioning
Key Features
- Threshold inhibition and crystal modification prevent hard CaCO₃ and CaSO₄ scale on tube surfaces
- Polymer dispersant component keeps suspended solids mobile for removal via blowdown
- Compatible with alkalinity and pH adjustment programs (NaOH, Na₂CO₃) standard in boiler water treatment
- Reduces blowdown frequency and heat loss from scale insulation, improving boiler thermal efficiency
- Suitable for systems with hardness breakthrough from softeners or when softener is temporarily offline
