Monitoring silica contamination is important to protect equipment and ensure heat exchange efficiency. It is particularly important in cogeneration applications where both the heat and water cycle are being used within the plant. Silica monitoring is a critical step in avoiding unplanned downtime, and an analyzer with trace sensitivity offers significant benefits. Find out how silica measurement works in this application note.

Silica Measurements Protect Expensive Equipment

Monitoring Chloride and Sulfate for Corrosion Control
Chloride and sulfate are the most corrosive ions in the water/steam cycle in a power plant. Typically monitored through sample testing, they can now be monitored on-line and in real time. With monitoring and control of chlorides and sulfates you can reduce pitting, stress corrosion cracking and other corrosion mechanisms that can damage expensive power components, reducing unplanned shutdowns and maintenance costs.

On-Line Chloride and Sulfate Analyzer for Power Plant Chemistry
Corrosion from chloride and sulfate ions under high pressure and temperature conditions is a serious issue for power plant turbines. METTLER TOLEDO Thornton's 3000CS Analyzer offers on-line measurement of chloride and sulfate ions at ppb levels and helps power plant personnel monitor water cycle chemistry to control corrosion and minimize damage. With trace level detection, the 3000CS allows power plant operators to take preventative action against corrosion before it causes unplanned shutdowns, generation loss, and costly repairs.
On-Line Sodium Measurement Enhances Power Plant Water Chemistry
Sodium is responsible for corrosion in high-value turbine blades and other parts of the cycle. Early detection of contamination allows time for planning corrective action before condenser leaks enlarge and serious damage occurs. Sodium is a key parameter for monitoring pure water treatment system performance and for detecting contamination within the thermal cycle.
The METTLER TOLEDO Thornton 2300Na Sodium Analyzer provides efficient and reliable monitoring of low sodium concentrations for these applications.
This video shows how the 2300Na Analyzer uses industry proven technology for measuring sodium, and adds innovative enhancements that simplify calibration and improve measurement reliability.
Silica Monitoring Can Be Done On-Line and Reliably for Power Generation
The presence of silica in boiler feedwater can very quickly lead to deposit formation in turbines. As it can only be removed during out-of-service cleaning, preventing silica from entering the water cycle is the best course of action. The 2800Si Silica Analyzer not only quickly detects trace-level contamination, the unit calibrates itself automatically, saving valuable operator time.
The METTLER TOLEDO Thornton 2800Si Silica Analyzer is a reliable on-line instrument designed specifically for pure water treatment and power cycle chemistry monitoring. Learn more about it in this video.
