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.)
