Steam and Water Analysis System (SWAS) is a system dedicated to the analysis of steam and/or water. In power stations, it is usually used to analyze boiler steam and water to ensure the water used to generate electricity is clean from impurities which can cause corrosion to any metallic surface, such as in boiler and turbine.〔http://instrumatic.com.co/portal/images/PDFS/laboratorio/steam_nopw.pdf〕 ==Steam and Water Analysis System (SWAS)== Corrosion and Erosion are major concerns in Thermal Power Plant operating on Steam. The steam reaching the Turbines need to be ultra-pure and hence needs to be monitored for its quality. A well designed Steam and Water Analysis system (SWAS)〔(【引用サイトリンク】url=http://www.forbesmarshall.com/fm_micro/downloads/SWAS/Specs-TPS-Super%20Critical-Once%20through%20Boilers-2010.doc )〕 can help in monitoring the critical parameters in the steam. These parameters include pH, Conductivity, Silica, Sodium, Dissolved Oxygen, Phosphate and Chlorides. A well designed SWAS must ensure that the sample is representative till the point of analysis. To achieve this, it is important to take care of the following aspects: 1) Sample extraction 2) Sample transport 3) Sample conditioning 4) Sample analysis 5) Sample hygiene 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Steam and water analysis system」の詳細全文を読む スポンサード リンク
