WJF Technical Articles Call Online Sodium Monitoring in the Water Steam Cycle – An Essential Parameter for Condensate, Feedwater and Steam Quality Assurance In the Condensate Pump Discharge (CPD) of water-cooled plants At the Condensate Polisher Outlet (CPO) In Saturated…

WJF Technical Articles Call Analytical Instruments in Water Steam Cycles – An Introduction for Non-Chemists Why Use Analytical Instruments? The aim of power cycle chemistry is to prevent corrosion and to avoid deposits in the power cycle. This will reduce…

WJF Technical Articles Call Phosphate Corrosion Control in Drinking Water Introduction Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides. Corrosion in water distribution systems can…

WJF Technical Articles Call Case Study – Protecting Power Station Performance with Gap-Free Conductivity Monitoring Data In an ideal world, continuous monitors would monitor continuously, but for some instruments downtime is necessary whilst service operations are undertaken. To overcome this,…

WJF Technical Articles Call Turbidity Measurement as Trend Monitor for Particulate Corrosion Products in Cycling Power Plants Application Corrosion product monitoring (e.g. total iron) is essential to determine the effectiveness of applied cycle chemistry treatment program in a power plant.…

WJF Technical Articles Call Introduction to Sample Conditioning and Sampling Systems in Water Steam Cycles Preface from the Authors A golden rule in analytical chemistry says: “The two digits before the decimal point are determined by sampling; the digits after…

The sampling system is used to take samples from the water/steam circuit and auxiliary systems for continuously measuring operational values and undertake laboratory analysis. The analysis allows monitoring of the water and steam quality and control over chemical dosing. Clearly,…
