  • Nalco Water Handbook, Third Edition > Boiler Feedwater Treatment
    Secondly, minimize iron returned via the steam condensate system by inhibiting condensate corrosion and maximizing the removal of any iron present in the returned condensate through use of condensate polishers / filters and automatic dump systems. .... The third leg of the triangle offense is to minimize corrosion from boiler feedwater and boiler water .
  • Boiler Water Treatment Principles and Practice
    When the problem is considered serious, it usually is removed by a condensate polisher . .... Soluble iron in MU often is associ- ated with manganese and usually (but not totally) is removed either by ion-exchange … in an aeration tower, where the process employs a combination of air or chlorine oxidation, followed by precipitation and filtration . .... No specific action usually is taken to remove silica (Si0 2) from MU water sources where the boiler plant operates at below 250 to 300 psig.
  • Nalco Water Handbook, Third Edition > Condensate Systems
    These impurities originate from dissolved solids introduced through condenser leaks, dissolved solids carried over with the steam from the boiler water , metallic species originating from condensate equipment corrosion, and various process contamination events. .... Condensate polishers can be used to improve the purity of condensate. .... The primary purpose of condensate polishers is to filter corrosion products such as iron and copper oxides (crud).
  • Crits Notes on Water and Ion Exchange
    – Iron corrosion products in startup condensate can be over 100–500 ppb and hopefully can be filtered . pH in condensate should be raised above 9.3 and hydrazine added as much as 100 ppb to reduce iron corrosion. .... Drum units with polishers should achieve <20 ppb iron at the econo- mizer. .... Extra blow-downs ( boiler or condensate) should be considered if iron is high. .... sodium balancing (54 ppb as Na/µS/cm of degassed cation conductiv- ity) when boiler water cation conductivity is…
