Challenges

  • Rapid loss of performance of turbine due to fouling especially effecting power output
  • Fuel and maintenance costs were too high

Solutions

  • Injection & washing equipment for online cleaning was installed
  • Auditing of existing cleaning regime was preformed
  • Custom Wash Cycle created & implemented
  • Started using Turbo-K® concentrate 1:4 for regularly scheduled online & offline cleanings

Highlights

  • Fuel cost savings due to improved machine performance = +$233,747.47
  • Maintenance cost savings due to machine’s less wear and tear = +$51,837.30
  • Increase in electricity production due to higher machine output = +$3,686.21
  • Total Annual Savings after costs deducted = +$255,638.86
  • Total Investment = 2,676.67
  • Amortization in years = 5 years
  • Internal rate of return (IRR) % = 9550%
  • Return On Investment (ROI) in months = 0.1

Operations by the numbers

  • Annual Maintenance Saving Due to Clean GT % = +4.50%
  • Annual Fuel Saving % = +1.68%
  • # Existing Crank-wash Operation Per Year = 0.51
  • # Crank-wash Per Year with Regular On-line Cleaning = 6.08

Plant operations benefited

  • Gas Turbine Maintenance Expenses - Reduced
  • Fuel Consumption - Reduced
  • Plant Production - Increased
