Abstract
A fuel supply system is provided having a first fuel gas compressor configured to be driven by a motor and a second fuel gas compressor configured to be driven by a shaft of a gas turbine system. The first fuel gas compressor and the second fuel gas compressor are configured to supply a pressurized fuel flow to a combustor of the gas turbine system, and the first fuel gas compressor and the second fuel gas compressor are coupled to one another in series.
Claims20
A system, comprising:
- a fuel supply system, comprising:
- a first fuel gas compressor configured to be driven by a motor;
- and
- a second fuel gas compressor configured to be driven by a shaft of a gas turbine system;
- wherein the first fuel gas compressor and the second fuel gas compressor are configured to supply a pressurized fuel flow to a combustor of the gas turbine system, and the first fuel gas compressor and the second fuel gas compressor are fluidly coupled to one another in series.
