HIGH VOLUME FLY ASH EXTRACTION / TESTING SERVICES


High Volume Fly Ash Extraction & Real-Time LOI Analysis

Collecting fly ash samples from economizer ash hoppers may be simple—but the results can be unreliable. Hopper samples often fail to represent the actual ash composition in the flue gas stream due to several factors, including:

  • Inconsistent ash collection frequency
  • Variations in particle size
  • Duct geometry and flow patterns
  • Flue gas velocities


High Volume Fly Ash Sampling: Accurate & Representative

SAS Global’s High Volume Fly Ash Sampling method directly captures fly ash from the flue gas stream itself—providing a true representative sample. This ensures accurate Loss on Ignition (LOI) data, giving you a reliable measure of combustion efficiency.


Fast, ASTM-Based LOI Analysis

Fly ash LOI analysis follows ASTM D3174, but SAS takes accuracy and speed further. Instead of a traditional muffle oven, we use a Hot Foil Instrument, which applies an electrical charge to achieve the necessary burnout temperatures. This advanced method delivers LOI results in minutes rather than hours, making it a powerful tool during combustion tuning—where real-time feedback is critical.


With SAS Global’s advanced sampling and analysis methods, you get faster, more accurate insights into your combustion performance—helping you maximize efficiency and minimize emissions.
