Liquid to dual-fuel LM6000

The upgrade encompasses 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.

• Vastly improves the versatility of the package by allowing the LM6000 turbine to operate on either liquid fuel or natural gas
• Improves operational flexibility by having the capability to switch from one fuel to another, and at full load with a CDP air-cooling system (if installed)

• 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, and check valves.
• A gas fuel manifold and fuel hoses are installed on the turbine and the liquid 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.
• Customers already configured for water injection can reuse the existing high-pressure liquid fuel water injection pumps.
• An optional CDP cooler can be added to allow fuel transfers at full load.
