SYSTEMS AND METHODS TO MAINTAIN STABILITY OF FUEL FLOW IN GAS TURBINE ENGINES

摘要

A system includes a gas turbine comprising a compressor section, combustor section, and a turbine section. The system further includes a first fuel line and a second fuel line coupled to the gas turbine. The system also includes a feed compressor disposed along the first fuel line upstream of the gas turbine. The feed compressor is configured to pressurize the first fuel provided to the gas turbine. Further, the system includes fuel flow maintenance system configured to provide a pressurized fuel to the first fuel line upstream of the feed compressor in response to an interruption in a flow of the first fuel along the first fuel line to the gas turbine that triggers a transition from the first fuel in the first fuel line to the second fuel in the second fuel line.
