Acoustic Monitoring Systems AMS for HRSG

The Acoustic Monitoring System is used for early tube leak detection on pulverized coal power boilers, recovery boilers, feedwater heaters and Heat Recovery Steam Generators, HRSG.

The Triple 5 AMS-3 for early tube leak detection has been used in conventional power boilers very successfully over the past 25 years. Non- invasive sensors, mounted on the boiler wall, are listening for a change in the normal background noise of the boiler that indicates a tube leak. The AMS-3 provides 24-7 real time data that tracks the progression of a tube leak. The same technology, and resulting benefits, is now being applied to HRSG’s.

HRSG operators report that tube leaks have been most troublesome at the Superheater and Reheater tube stub welds to the headers and Reheat drain areas. Early knowledge of these leaks provides a plant with information to make decisions on continued operation of the unit and scheduling repair during a planned outage.

Benefits

• Early indication of a tube leak, before traditional plant methods
• Reduce secondary damage
• Manage power market exposure and risk
• Locate area of leak(s) before unit comes offline
• Trend severity and progression of leak with real-time data
• Schedule maintenance vs forced outage
• Preplan jobs with correct assets
• Scalable installation options
• Reduce maintenance costs
