In modern power plant operation, the stability and purity of the water system are core elements ensuring the safe and efficient operation of the units. From the main steam cycle to desulfurization and denitrification processes, even slight fluctuations in water quality can lead to equipment corrosion, scaling, and even shutdown risks.
To address this, Rosemount™, with its mature water analysis technology and a full range of reliable products, builds a robust "water quality defense line" for power generation systems.
Accurate Protection Under Low Conductivity Conditions
In steam and water sampling systems, the high temperature, high pressure, and low conductivity conditions place extremely high demands on measurement equipment. The Rosemount 1056 multi-parameter transmitter paired with the 3900 series pH electrode is the ideal combination for this scenario.
The 1056 transmitter boasts powerful signal processing capabilities and a temperature compensation algorithm, enabling precise correction of measurement deviations. The 3900 electrode utilizes a fouling-resistant TEFLON liquid junction in a dual salt bridge reference structure, complemented by a specially designed glass membrane, maintaining stable response even in low-conductivity water samples.
Practical applications demonstrate that this configuration maintains excellent response speed and measurement accuracy in low-conductivity environments, effectively preventing unplanned downtime caused by water quality anomalies and significantly improving unit operational reliability.
Dirty and Corrosion-Resistant Desulfurization Measurement
In flue gas desulfurization (FGD) systems, the slurry pH value directly determines desulfurization efficiency and byproduct quality.
The Rosemount 396R dirt- and corrosion-resistant pH electrode is designed for high-solids-content, corrosive environments. It features a dual-liquid junction, two-stage spiral reference electrode path, and a wear-resistant all-titanium sheath, resisting ion poisoning and wear, significantly extending its service life. Combined with the intelligent diagnostic function of the 1056 transmitter, it achieves long-term stable measurement.
Industry technical analysis indicates that analytical systems with self-diagnostic and remote communication capabilities can help maintenance personnel monitor equipment status in real time and provide early warnings of faults, making them a key component in predictive maintenance and the construction of smart power plants.
Stable Monitoring of High-Purity Water Quality
Furthermore, the Rosemount EWCA silicon-sodium-phosphorus analysis system is fully optimized for high-requirement scenarios such as pure water, integrating open sampling and high-precision metering pumps. It can achieve stable measurements under fluctuating user pressure conditions and is widely used in makeup water and steam generator feedwater monitoring, ensuring consistently controlled water and steam quality.
Precisely Safeguarding the Power Industry
These products can optionally support protocols such as HART or Profibus, allowing seamless integration with DCS or smart power plant platforms, facilitating digital and visual management of water quality across the entire plant. In today's power industry's transition towards intelligent and green transformation, Rosemount uses technology as its pen and reliability as its ink to write a high-standard answer to water quality analysis. From core components to system solutions, it consistently stays at the forefront of the industry, safeguarding the safe operation of power plants.
