Ge Gas Turbine Frame (9fa)

1. The document outlines the steps to start up a GE gas turbine frame (9FA) unit from standstill. 2. It involves increasing the unit's RPM in stages from 0 to 3000 RPM while controlling oil pressures and opening/closing different valves and components. 3. The final step is to run the unit at 8% load and then increase to 120 MW load while operating in primix mode with different combustors.
