Southern Mississippi Electric Power Association Power Station

Southern Mississippi Electric Power Association Power Station

The Southern Mississippi Electric Power Association (SMEPA) uses SimSci to improve efficiency at their Hattiesburg station.

  • Depending on the load, potential heat rate improvements up to 1.5% are expected. This benefit will provide a project payback of less than one year.

  • Goals

    • Improve the performance of the Riley turbo-fired units
    • Improve the mill’s impact on the energy efficiency of the furnace
    • Lower NOx emissions
  • Challenges

    • Improve heat rate and boiler efficiency while maintaining low NOx emissions
  • Results

    • Expected heat rate improvements of 1.5%, providing a project payback of less than one year
    • Expert System at soot blower maximizes heat transfer area in the furnace
    • Model Predictive Control provides increased boiler efficiency while maintaining steam temperatures and remaining within NOx specifications
