LP & HP Boiler Dosing System – Datgur Engineering

The system includes chemical storage tanks for oxygen scavengers and treatment chemicals, precision metering pumps for accurate injection, and a PLC-based control panel for automated operation.

Analytical sensors continuously monitor pH, conductivity, dissolved oxygen (DO), and ORP levels.

Corrosion-resistant injection quills ensure safe and uniform chemical dispersion into low-pressure and high-pressure boiler feedwater lines.

Oxygen scavengers eliminate dissolved oxygen to prevent pitting corrosion.

Alkalinity agents maintain proper pH levels to neutralize acidic conditions.

Scale inhibitors prevent mineral deposition that can impair heat transfer efficiency.

For high-pressure boilers, phosphate treatment helps precipitate hardness into manageable sludge.

Amine-based compounds protect condensate return lines by maintaining controlled pH levels throughout the system.

Sensors continuously analyze feedwater chemistry and transmit data to the PLC control system.

Flow-proportional dosing logic adjusts chemical injection rates based on boiler load fluctuations.

Multi-stage injection allows tailored dosing for LP and HP sections independently.

An automated feedback loop monitors treated water parameters and optimizes chemical consumption in real time.

Low-pressure boiler systems primarily focus on oxygen removal and pH stabilization to prevent corrosion.

High-pressure boiler systems require more complex treatment regimens including precise phosphate and inhibitor dosing to prevent carryover and tube overheating.

Automated control enhances safety by reducing manual chemical handling and ensuring consistent treatment accuracy.

Widely used in power generation plants where turbine protection demands high-pressure precision, the system is also suitable for chemical processing industries with variable steam loads.

Food and pharmaceutical facilities rely on treated steam for purity and contamination prevention, while district heating and HVAC networks use these systems to prevent scaling and efficiency losses.
