Boiler Feedwater System

Boilers, reboilers and condensers are very sensitive to corrosion and fouling.

Continuous measurement and control of critical water parameters conserves energy and treatment chemicals by eliminating excessive blowdown going to waste. They also help minimize corrosion and ensure the highest water purity.

 

pH/ORP sensors

  • pHure Sensor™ with ISM and unique reference system maintains measurement continuity under low conductivity conditions
  • Single probe design and low volume flow housing prevent solids accumulation
  • Combined measurement of ORP and pH with the same electrode

Dissolved oxygen sensors

  • Intelligent Sensor Management enables predictive maintenance program for efficiency
  • Lowest ppb range sensitivity
  • Simple drop-in membrane cartridge design reduces maintenance and spare parts requirements

TOC in-line sensors

  • Continuous monitoring for organic contamination in makeup water ensures quality
  • Thornton provides in-line detection of organic contaminants in cogeneration condensate return to prevent organic acid corrosion

Degassed Cation Conductivity System

  • Fully automated operation saves time and cost
  • Highly accurate and reliable conductivity measurement using UniCond sensors with ISM

Sodium analyzer

  • Sub-ppb sensitivity
  • Unattended automatic calibration saves operator time
  • pH confirmation of reagent addition to assure reliable measurement

Silica analyzer

  • Automatic zero adjustment with every measurement for stability
  • Convenient grab sample measurement
  • Adjustable measurement timing

Conductivity sensors

  • UniCond® digital sensors with ISM have exceptionally wide measurement range and accuracy 
  • Highly accurate specific and cation conductivity due to precise factory sensor calibration and temperature compensation
  • Widely spaced electrodes allow unrestricted sample flow and no solids accumulation

UniCond 4-electrode Conductivity Sensor

  • Greater than 20% improved accuracy over analog sensors
  • Highly repeatable accuracy due to patent pending calibration system
