  • Marks’ Standard Handbook for Mechanical Engineers, Eleventh Edition > CORROSION
    Once-through boilers typically use full-flow, mixed - bed polishers (preferred) or precoat (with crushed ion exchange resin) filters . Mixed-bed condensate polishers also are strongly advised for drum-type steam generators with condenser cooling water …

    This requires a inlet/ outlet collector or distributor added to the filtering or ion - exchange tank. – S.B. Applebaum in the 1960s had the same idea and applied it to the “Filterex” hot zeolite condensate polishers in industrial boilers. – It was also applied to mixed beds by applying air into the interface (regen.) collector and rinsing out this same port in the same manner practiced by Flynn.
  • Nalco Water Handbook, Third Edition > The Power Industry
    For the best cost performance, regenerable mixed bed polishers are commonly operated at service flow rates over 50 gpm/ft 2 (122 m 3/[h · m 2]), about 10 times the rate employed in raw water demineralization. The finely ground resin particles provide good filtration and excellent kinetics for ion exchange . This type of condensate polisher is typically operated at service flow rates of about 4 gpm/ft 2 …

    Also a condensate mechanical filtration system can be considered. The principle for SG blowdown purification deals with issues similar to CPS, since both are using ion exchange resins with their specific characteristics. Most of the countries regenerate their resins and use a cationic bed for conditioning reagent elimination, thus frequently regenerated (depending on the operating pH and the type of conditioning reagent) followed by a mixed bed, as a polisher (explaining the use of …
