Boiler Chemistry Control and Treatment of Feed Water

Also high concentrations of deposits cause corrosion. So some treatment of feed water is necessary. Details related to boiler water chemistry can be found in Chapter V of Power Plant Instrumentation and Control Handbook: A Guide to Thermal Power Plants (Here only treatment part is discussed, with special reference to Supercritical boilers.)

Controlling the PH of water is the first step towards boiler treatment. We all know that if PH is below 7 the solution is acidic and above 7 it’s alkaline. For boiler water PH is maintained between 11-11.8 and that of feed water between 7-9. Effects. If either of the values increases, water will accordingly become acidic or alkaline, leading
