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.)

Soft Water: A Must For Commercial Water Heating …

Boiler Benefits – Do you have a boiler as part of your water heater setup?If so, you have one more reason to use softened water. Sediment in a boiler can clog the heat exchanger, (the tube inside the boiler responsible for keeping the water hot) and eventually that heat exchanger will give way and spring a leak.Then you're left with a water heating system that can't maintain hot water
