Conditioning of boiler feed water with phosphates


Boiler feedwater - WikipediaBoiler feedwater can be protected from corrosive conditions through coordinated phosphate/pH control treatment. Phosphate buffers the boiler water, reducing the chance of large pH swings due to the development of caustic concentrations. In phosphate treatment, excess caustic combines with disodium phosphate to form trisodium phosphate.Characteristics of boiler feedwater - Lenntech16/7/2009 · 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 to detrimental effects caused due to acidic attack or caustic embrittlement. This may damage the …

Boiler water treatment - LenntechThe treatment and conditioning of boiler feed water must satisfy three main objectives: Continuous heat exchange. Corrosion protection. Production of high quality steam. External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed Boiler Feed Water Treatment - EWT Water Technology5/5/2018 · The boiler feed water (c), mainly consisting of make-up water (b) and returning condensate (e), flows from the boiler feed water tank (2) into the steam boiler (3), where evaporation occurs. From there, the main steam (d) flows into the process (4) and condenses.
