• With the advent of higher pressure boilers and more restrictive feed water requirements of turbine manufacturers, the ion exchange equipment manufacturers were called on to meet the challenge of purifying very large quantities of water which contained very small quantities of both dissolved and suspended contaminants. The major dissolved contaminants were sodium, chloride, and silica, while the suspended contaminants were oxides of iron and copper.
  • H&T provides two different condensate polisher systems—sodium-cycle polishers for lower-pressure boilers and externally regenerated mixed-bed condensate polishers for high-pressure or super-critical boilers. The objective is to filter any crud and exchange any trace contaminants picked up in the condensate loop. The externally regenerated mixed-bed polisher vessels are designed for the operating pressure and temperature of the condensate return line.
