Challenges

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

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 = +$12,650.13
  • Maintenance cost savings due to machine’s less wear and tear = +$5,410.21
  • Additional revenue from available production due to less machine downtime = +$3,148.28
  • Increase in plant production due to higher machine output = +$8,302.37
  • Total Annual Savings after costs deducted = +$ 25,444.02
  • Total Investment = $1,200.00
  • Amortization in years = 5 years
  • Internal rate of return (irr) % = 5.0%
  • Return On Investment (ROI) in months = 0.6

Operations by the numbers

  • Annual Maintenance Saving Due to Clean GT % = +4.50%
  • Annual Fuel Saving % = +1.26%
  • Production Increase Factor = + 33.17%
  • Total Annual Downtime (Existing GT's Crank-Wash) = 26.07 Hours
  • Total Annual Downtime with On-line System Operation = 10.95 Hours
  • # Existing Crank-wash Operation Per Year = 8.69
  • # Crank-wash Per Year with Regular On-line Cleaning = 3.65

Plant operations benefited

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