Retrofitting Gas Turbines for Higher Efficiency

Gas turbines used in ammonia plants can also be upgraded with advanced technology parts to improve power output and to reduce heat rate or firing required per power output (FAI, 2013). Possible measures that can be taken include:

  • Optimal clearance of turbine blades
  • Combustion liners (to increase inlet temperature of turbine)
  • Adjustments to turbine blades (to allow higher temperatures) (Worrell, 2013)
