Fuel Gas fuel system supplies gaseous fuel with adequate mass flow to the gas turbine. Fuel oil system as an option supplies liquid fuel with adequate mass flow to the gas turbine. Optionally, a dual-fuel system provides highest fuel flexibility.
Rotor turning Turning device – the gas turbine rotor is rotated at low speed, for start-up, shutdown, and extended standstills.
Hydraulic Clearance Optimization The HCO (Hydraulic Clearance Optimization) power unit, supplies hydraulic oil for shifting the gas turbine rotor into the best-perfor- mance position with minimized clearances on the turbine side.
Cleaning A mobile compressor cleaning system supplies water for the compressor wash procedure to maintain high compressor efficiency.
Start-up Starting frequency converter (SFC) for static start-up.
Valve actuation A hydraulic oil system provides high- pressure hydraulic oil to operate the control and emergency stop valves of the fuel systems and NOX water system. Instrument air system for the supply of compressed air to operate the pneumatic actuators (e.g., blow-off valves).
Lubrication Lube oil system – supplies lubrication oil to the gas turbine, the generator, and the HCO power unit and supplies lifting oil to the gas turbine, the generator, and the hydraulic-type rotor turning device.
