LP & HP Boiler Dosing System
Comprehensive chemical treatment systems designed to prevent scaling, corrosion, and fouling in low-pressure and high-pressure boiler feedwater.
lpSystem Advantages
1. Essential System Components
Chemical Storage Tanks:Dedicated containment for oxygen scavengers, pH adjusters, and inhibitors.
Precision Metering Pumps:High-accuracy pumps to control the exact flow of treatment chemicals.
Advanced Control Panel:Automates dosing rates based on real-time water quality data.
Analytical Sensors:Monitoring pH, Conductivity, and ORP to optimize chemical consumption.
Injection Quills:Specialized hardware for safe chemical dispersion into high-pressure feedwater lines.
2. Strategic Chemical Treatments
Oxygen Scavengers:Essential for removing dissolved oxygen to prevent pitting and corrosion.
Alkalinity Agents:Raising pH levels to neutralize acidic corrosion within the boiler shell.
Scale Inhibitors:Preventing mineral buildup on tubes that impairs heat transfer and causes overheating.
Phosphate Treatment:Specifically for HP boilers to precipitate hardness as manageable sludge.
Amine Compounds:Protecting condensate return lines from corrosion by controlling pH levels.
3. Operational Workflow
Continuous Quality Monitoring:Sensors provide a live stream of feedwater chemistry data.
Flow-Proportional Dosing:Adjusting chemical injection rates based on fluctuating boiler loads.
Multi-Stage Injection:Tailored dosing for both LP (Low Pressure) and HP (High Pressure) sections.
Automated Feedback Loop:Real-time system adjustments based on post-dosing water quality analysis.
4. LP vs. HP Boiler Requirements
Low-Pressure (LP) Systems:Focused on basic oxygen scavenging and pH control for moderate climates.
High-Pressure (HP) Systems:Complex regimens involving precise phosphate and inhibitor control to prevent carryover.
Safety & Reliability:Automated systems minimize hazardous manual chemical handling and human error.
5. Industrial Applications
Power Generation:High-pressure boilers requiring extreme precision for turbine protection.
Chemical Processing:Managing diverse steam loads with tailored chemical regimens.
Food & Pharma:Ensuring high steam purity to avoid product contamination.
District Heating:Preventing scale and efficiency loss in massive HVAC networks.
