Benefits

What can upgrading do for you?

The modification includes the addition of dual-fuel manifolds with water injection capability, dual-fuel nozzles, metering valves, shutoff valves, liquid fuel boost skid, and control system updates as needed.

  • Improved versatility of the package by allowing the LM6000 turbine to operate on either liquid fuel or natural gas.
  • Availability of the package can be maintained in the event of a disruption to natural gas fuel supply.
  • Increased operational flexibility—and profitability—introduced with the capability to switch from one fuel to another, even at full load. CDP air-cooling system is required for full load transfers.

How we get you there

  • The upgrade includes on-engine, off-engine, and the off-package liquid fuel delivery and filtration skids, along with updated controls software and hardware, to yield a unit capable of operating on either natural gas or liquid fuel.
  • Main mechanical changes consist of installing all major components and piping to supply liquid fuel from the customer connection (flanged outside of main base) to the on-engine liquid fuel manifold.
  • Standard package components consist of a fuel-metering valve, shutoff valves, check valves, and fuel return lines.
  • New liquid fuel manifolds and fuel nozzle tubes are installed on the turbine and the gas fuel nozzles are replaced with dual-fuel nozzles.
  • A gas purge system and a compressor discharge pressure (CDP) purge system is also installed.
  • Gas fuel is used to purge the liquid fuel system while operating on gas fuel to prevent backflow from the combustor.
  • CDP air is used to purge the gas-fuel system during liquid fuel operation to prevent coking of the gas fuel circuit and backflow from the combustor.
  • 50Hz and 60Hz can be selected, adding applicable 50Hz and 60Hz parts and maintaining common parts to both systems. A CDP cooler can be selected for both 50Hz and 60Hz options.
  • Customers already configured for water injection must replace the water injection pumps with high-pressure pumps to properly operate on liquid fuel and meet 42 ppm NOx.
  • An optional CDP cooler can be added to allow fuel transfers at full load.
  • Optional liquid fuel forwarding and boost pump skids are available separately.
