Seven Sins of Steam SamplingBy SWAN Analytical Instruments
This free whitepaper illustrates the most common SWAS design 'sins', using a broad palette of sampling system examples from around the world.
Alternatives illustrate that a water / steam sampling system does not have to be purgatory for the plant chemist and that reliable measurements, ease of maintenance, and low-cost of ownership can be achieved.
Over the past 20 years, the main components of power plants, such as gas turbines, steam turbines, boilers, and plant control systems have been continuously improved. Strangely, during the same period, the steam / water analysis system has hardly seen any changes.
For engineering, procurement, and construction contractors and boiler manufacturers, it is still common practise to specify designs which are out of date. Neither the changed requirements of modern power plants, nor the possibilities offered by state-of-the-art online instrumentation are taken into account.
