This upgrade provides the capability to run either on gas or liquid fuel, with or without water injection for NOx control. The modifications consider the addition of dual-fuel manifolds with water injection capability, including metering, shut off valves, boost skid and controls update as needed.

Applicable Turbine Models

LM2500

Upgrade Benefits

  • Easily switching between fuels allows increased site power generation flexibility.
  • Maximize profitability by switching to a cheaper fuel depending on market conditions.
  • Increased power output using the water injection capabilities.
  • Switching to gas fuels lowers NOx emissions.
  • Gas fuels also have higher power outputs.
  • Can use either Woodward, GE Mark VI / Mark VIe, or RX3i controls systems. 
  • Increase Uptime
  • Enhance Operational Flexibility
  • Improve Maintainability
  • Lower Environmental Footprint

How it works

  • For adding gas fuel capabilities:
    • A dual fuel manifold with water injection consisting of two liquid fuel manifolds, a gas manifold, and 30 dual fuel nozzles.
    • Gas fuel compressor (off-package if required to boost gas pressure).
    • Gas fuel coalescer/dehumidifier and/or a filter/scrubber skid (off-package). 
    • A fuel-metering valve (on-package).
    • Gas shutoff valves, check valves, and vents (on-package).
  • For adding liquid fuel capabilities:
    • A liquid fuel forwarding skid with a 2’’ pipe customer connection with 5 psig Flooded Suction (off-package).
    • Fuel filtered to 10 μm absolute (off-package).
    • 2 liquid fuel manifolds, hoses, and fuel nozzles will be added on-engine (on-package).
    • Simplex liquid fuel boost skid (off-package).
    • A duplex low pressure filter skid (off-package).
    • Fuel metering valves (on-package).
    • Liquid fuel shutoff valves, check valves, and return fuel lines (on-package).
  • Both liquid and gas fuel conversions involve installing connections to customer fuel connections (flanged outside main base) and changing the fuel manifolds.
  • Controls software logic and HMI changes will also be needed.
