boiler feedwater treatment (part ii): water treatment

Boiler Feedwater Treatment (Part II): Water Treatment

Internal treatment can constitute the sole treatment when boilers operate at low pressure, large amounts of condensed steam are used for feedwater, or the raw water available is of good quality. However, in moderate or high-pressure boilers, External treatment of the make-up water is mandatory for good results.

Boiler Feedwater Treatment (Part I): Why Water Treatment

The feedwater (make-up water) from outside needs to be treated for the reduction or removal of impurities by first filtration, and then followed by softening, evaporation, deariation, ion exchange etc. Internal treatment is also required for the conditioning of impurities within the boiler system, to control corrosion, as reactions occur in the
