Heavy-duty gas turbine (50 Hz) SGT5-9000HL

Siemens HL-class gas turbines are paving the way to the next level of efficiency and performance. Derived from proven Siemens H-class technology in an evolutionary development step, the next generation of Siemens advanced air-cooled gas turbines uses a series of new, but already tested technologies like super-efficient internal cooling features for blades or vanes and an advanced combustion system to increase firing temperature. The result: A technology carrier to the next level with a combined cycle efficiency beyond 63%, with a midterm goal of even higher efficiencies. The new Siemens HL-class consists of three engines: SGT5-8000HL, SGT5-9000HL and SGT6-9000HL.
