Cogen Boiler Blowdown Control Using Conductivity

In sugar and ethanol plants, return condensate is recirculated to the boilers to generate steam. The evaporation of this steam leaves behind an increasing concentration of minerals that cause scaling and under deposit corrosion. This damage leads to boiler tube failures and requires plant shutdown for cleaning and expensive maintenance. Using conductivity measurement for boiler blowdown control can be a very effective way to keep mineral concentrations within an acceptable range and increase the efficiency and life of the boiler.   

The application note highlights:

• Conductivity for Monitoring Mineral Concentration
• Boiler Conductivity Measurement
