Presentation Transcript

  1. Feedwater Heater Heat Transfer Richard Galati Brent Smith Justin Pierce

  2. Overview • Intermountain Power Plant • Provides power to Los Angeles • 2 Generator Units • 950MW output each • 1900MW Total Output • Proposed 3rd unit will make it the 13th largest generating station in the US

  3. The Feedwater Heater

  4. Overview • Feedwater Heater • Condenses steam • Preheats water before entering boiler • Increases efficiency and total BTU output

  5. Feedwater Heater

  6. Heat Transfer • Finding Heat Transfer • Variables Provided by Manufacturer • Un - Stage Thermal Resistance • An - Stage Area • Log Mean Temperature Difference • All temperature values provided from instrumentation on feedwater heater

  7. Heat Transfer • Q for each stage is calculated • De-Superheating • Condensing • Drain Cooling • Qtot = Qds + Qc + Qdc • Results compared with projected data from manufacturer

  8. Conclusions • Qtot, predicted = 161.91x106 BTU/hr • Qtot, actual = 144.5x106 BTU/hr • Difference = 17.41x106 BTU/hr • Why: • 20 years of use • Increase of Flow Rate • Other…
