LIBS APPLICATION FOR THERMAL PLANTS MONITORING

  • Abstract:
    A LIBS technique has been applied to detect alkali metals under high pressure and high temperature conditions, and an automated LIBS unit has been developed and applied in a month-long monitoring experiment. The results were compared to those obtained using the conventional sampling method, showing good agreement. LIBS can detect Na and K at ppb levels, even under the high pressure conditions appearing in PFBC and IGCC thermal power plants. LIBS is capable of 1 minute detection time, as compared to the 20 hour sampling time required by the conventional method, and offers various merits as a tool for actual plant monitoring.
