Silica Measurements in Power Plants

Protect your plant AND optimise plant efficiency

Close monitoring of Silica concentrations helps ensure power plant efficiency and reduce downtime by avoiding costly plant shutdowns and repairs.

Why measure silica?
A deposit of 0.1mm can reduce thermal transfer by 5%.
If there is even a tracelevel of silica in the water when it is heated to steam it can deposit itself on the blades of a turbine in a very short period of time. Silica deposits affect how a turbine spins and causes:

  • Reduced capacity and efficiency of the turbine
  • Increased maintenance costs
  • Unscheduled plant shutdown for repair or exchange of blades

The HACH 5500 sc silica analyser reduces maintenance time and user interaction due to a number of customer-driven improvements:

  • 90 days of continuous runtime with only 2 litres of each reagen
  • Save time on maintenance with the industries only pump-less reagent delivery system
  • Avoid downtime with predictive diagnostic tools, warning LEDs and high-visibility notification screen
  • Clean, fast and easy reagent change with re-designed bottles and ready-to-use reagents
  • Easy verification with Hach lab test with Grab Sample In and Out features

Hach reagents provide a number of advantages:

  • Formulated for optimal accuracy – factory pre-mixed with extensive quality control 
  • Instantly ready-to-use
  • Designed with user friendly features like color-coded caps and sealed bottles allowing quick and clean reagent replacement

Do you value flexibility over the convenience and accuracy of pre-mixed reagents? Then you need the POLYMETRON 9610 silica analyser.
