Boiler feedwater quality is a critical factor in power plant operation, as it directly determines heat transfer efficiency and equipment service life. Poor water quality can easily lead to pipeline scaling, corrosion, and deteriorated steam quality, resulting in increased unit energy consumption and unplanned outages. Therefore, boiler feedwater monitoring is a core part of water-steam cycle management in thermal power and cogeneration plants.
Shandong Dongrun Instrument develops online boiler feedwater quality monitoring equipment specifically for power plant conditions. It is fully adapted to high-purity water monitoring scenarios such as boiler make-up water, deaerator outlet water, and condensate water.
The equipment strictly complies with power plant water-steam quality standards and enables real-time, accurate monitoring of key trace parameters, including conductivity, cation conductivity, dissolved oxygen, pH, sodium, and silica. It supports ppb-level high-precision detection and meets strict water control requirements for supercritical and subcritical units.
Equipped with a dedicated sampling pretreatment system, it adapts to high-temperature and high-pressure water samples, effectively filters impurities, stabilizes sample temperature and pressure, eliminates data fluctuations, and ensures long-term continuous monitoring accuracy and stability.
The complete system adopts industrial explosion-proof and dust-proof design to adapt to the complex environment of power plant rooms. It supports automatic calibration and intelligent cleaning, significantly reducing manual maintenance frequency. The equipment is compatible with 4-20mA, RS485, Modbus, and other signal outputs. It can be directly connected to the plant’s DCS and smart power management platforms, uploading water quality data in real time and automatically alarming under abnormal conditions, so that operation and maintenance personnel can adjust water treatment processes promptly.
As a professional manufacturer of power plant water quality monitoring systems, Shandong Dongrun Instrument provides end-to-end services, including equipment customization, installation and commissioning, system integration, and after-sales operation and maintenance. We help power plants achieve routine and digital management of boiler feedwater quality, effectively reduce the risk of equipment corrosion and scaling, and ensure efficient, safe, and stable unit operation.
