SWAS Systems for Power Plant Units
← Back to Energy applications
Supply of sampling, conditioning and analysis (SWAS) systems for the water-steam cycle of four power plant units.
Why the water-steam cycle is measured
In a power plant cycle, water chemistry directly affects corrosion and deposit risk. Measurements such as cation conductivity, pH, dissolved oxygen, silica and sodium help protect the turbine and boiler.
Parts of a SWAS system
- Sampling points and high-temperature lines
- Cooling and pressure reduction to bring the sample to safe conditions
- Analyzers measuring the conditioned sample
- Transfer of measurement signals to the control system
