  1. for Boilers Boiler Performance Automation Chris Golden Senior Account Manager Nalco Company

  2. for Boilers 3D TRASAR for Boilers  3D TRASAR for boilers delivers maximum performance. • Safer operation • Improved system reliability • Lowest Cost of Operation  Technology scope • Advanced monitoring & control • Performance sensors • New chemistry • Software • Wireless communication Performance Management for Boiler Systems

  3. Boiler Sample 3D TRASAR Boiler Basic System @T ORPTM Controller & Fluorometer

  4. TRASAR Automation 45 TRASAR Automation 40 Detect System Upsets 35 30 ppm 22310 25 ppm 22310 20 15 10 Optimum Operation 5 0 10/11/1997 20/11/1997 30/11/1997 10/12/1997 20/12/1997 30/12/1997 09/01/1998 19/01/1998 Date 3D TRASAR Internal Treatment Automatically responds Maintain optimum treatment levels Keeps your boiler clean Good for Boilers from 10 psig to over 2400 psig

  5. 3D TRASAR Preboiler Corrosion Control @T ORP Starter Controller & T3 Fluorometer Boiler Sample 3D TRASAR Preboiler Corrosion Control

  6. Preboiler Corrosion Control Vision • Today: • Test Oxygen • Test Scavenger Residual • Inspect Equipment • Tomorrow: • Continuous, Real-Time Measurement of Corrosion Potential • Automation of Oxygen Scavenger Feed

  7. -100 0 -200 -100 -300 -200 @ Temp Orp (mv) RT ORP (mv) -400 -300 -500 -400 -600 -500 -600 -700 Time (hrs) @T ORP vs RT ORP(at Temp vs Room Temp – 200 MW Coal Fired Plant) @T ORP more sensitive than RT ORP to optimize CHZ feed

  8. @T ORP vs Dissolved O2 ORP Cell Internal Configuration @T ORP faster response than DO monitor

  9. Low Chemical Treatment High 3D TRASAR Preboiler Corrosion Monitoring Typical Corrosion Control High Underfeed Results in Corrosion Potential Overfeed leads to Excess Treatment Costs Low Today we have fixed feed rates regardless of the boilers water’s potential to corrode

  10. New Best Practice for Preboiler Corrosion Control @T ORP • Performance based control of corrosion stress • Maintains “Reduced” Conditions • Minimizes corrosion • Promotes passivation Customer Value • Safety, Reliability • Mitigates failures • Reduce boiler iron deposits • Minimize Cost • Asset protection • Minimize downtime • Maximize Availability • Improve turbine efficiency
