Steam & Water Analysis System (SWAS)
A fully integrated Steam and Water Analysis System engineered to provide exact, precise measurements on all critical water chemistry parameters. Designed to keep your power plant running with minimum erosion and corrosion.
In any power plant running on steam, the purity of boiler feed water and steam is absolutely crucial to protect steam turbines, boilers, superheaters, condensers, and other steam equipment from scaling and corrosion damage.
Operating Range
Up to 560°C / 250 bar
Critical Water Chemistry Analysis
On-line steam and water analysis of critical parameters is essential to prevent damage from scaling and corrosion. Our SWAS monitors all key parameters continuously.
pH
Continuous monitoring of water chemistry balance to prevent corrosion in boiler systems
Conductivity
Specific and cation conductivity measurement for detecting contamination in steam and water
Dissolved Oxygen
Critical for preventing pitting corrosion in boiler tubes, feedwater heaters, and condensate systems
Silica
Monitoring silica levels to prevent turbine blade deposits and scaling in high-pressure systems
Sodium
Early detection of condenser tube leaks and demineraliser breakthrough through sodium analysis
Hydrazine & Phosphate
Chemical treatment monitoring to maintain optimal dosing levels for corrosion inhibition
Dual Panel Configuration
The SWAS is configured as a two-panel system: a Wet Panel for sample conditioning and a Dry Panel for analysis and signal processing. This separation ensures optimal instrument performance and simplified maintenance.
Wet Panel
Sample Conditioning
Samples from different process points are fed to this panel. Contains all sample conditioning components to reduce temperature and pressure to levels suitable for analytical instruments. Sensors in this panel feed output to the Dry Panel.
Dry Panel
Analysis & Control
Contains all analytical instruments, transmitters, annunciators, and indicators. All remote signals are transmitted from this panel to the control room DCS/PLC for centralised monitoring and alarm management.
