Water quality of bolier. Most of the time you have more restrictios with steam quality in the ST that in the HRSG or in the Boiler. The Siemens-Westinghouse clas G (gas turbines) also will require an exceptional steam quality for cooling in the TP and Total Volatil treatment (No Phosphate) SiO2< 5PPB; Cation Cond < 0.2umhos Sodium <5 PPB and very low levels of Iron.

Get a QuoteWhen a large amount of feedwater enters the boiler, the steam space above the water level becomes foggy. This fog and the resultant water-contaminated, low-quality steam continue until the water in the boiler becomes reasonably isothermal. The second problem is the suppression of the rate of steam production.
