SYSTEM AND METHOD FOR OPERATING A GAS TURBINE ELECTRIC POWER PLANT WITH BYPASS FLOW FUELING OPERATION TO PROVIDE IMPROVED RELIABILITY AND EXTENDED APPARATUS LIFE

摘要

A gas turbine electric power plant is provided with an industrial gas turbine which is operated by a computer control system. The gas turbine is provided with a liquid fuel system having a turbine driven pump which supplies fuel to turbine nozzles through a throttle valve. A bypass pump pressure regulator valve and a bypass pressure temperature limiter valve function together to provide stable fuel pressure operation and stable turbine inlet air temperature operation during ignition and other turbine operating periods. Such bypass means are operated substantially independently of the control system.
