General Product Information
To help you improve the performance of your gas turbine and your plant competitiveness Siemens Energy Service offers many innovative solutions. One of these is the Hydraulic Clearance Optimization (HCO) upgrade.
The performance enhancement feature of the Hydraulic Clearance Optimization upgrade is achieved by shifting the rotor against flow direction to optimize turbine clearances during steady state operation. The axial shift of the rotor is performed automatically by hydraulic pistons behind the compressor thrust bearing. This shift results in a power and efficiency increase after a one hour warm-up period.
