Keeping water quality at optimal levels for steam generation is essential to preventing inefficiency and premature corrosion or failure of turbines.
Yokogawa's Wet Chemistry Analyzers are highly reliable and used for water analysis of sodium, silica, hydrazine, and phosphate, helping operators minimize and mitigate the increased risk failures caused by corrosion and associated component failures.
Power plants and other steam generation processes use water as their main medium, either for cooling in liquid phase or in gas phase as a drive for turbines. Sodium, silica, hydrazine, and phosphate are commonly measured in makeup and boiler feed water, inside the boiler drones, for boiler blowdown, demineralized water, and in steam condensate water for leak detection.
General example of power generation
The WE410 Silica Analyzer is used for silica content monitoring in thermal power plants to protect systems and lower reagent consumption.
The WE420 Sodium Analyzer is an online continuous analyzer that uses ion selective electrode and reference electrode to measure sodium concentration.
The WE430 Hydrazine Analyzer is an online continuous analyzer that uses an ion-selective electrode to measure the voltage potential between the sensing element and reference electrode.
The Yokogawa WE440 Phosphate Analyzer is a continuous online analyzer used for early detection and precise phosphate monitoring in the boiler water supply.
