Abstract (en)
[origin: WO2017189566A2] A large frame heavy duty industrial gas turbine engine that produces twice the power as conventional single spool industrial engines and operates at full power during a hot day. The engine includes a high spool directly driving an electric generator at a synchronous speed of the electric power grid, a low spool with a low pressure turbine (LPT) driving a low pressure compressor (LPC) from the exhaust gas from the high pressure turbine.. The low spool can operate at a higher speed than at the normal temperature conditions to produce high mass flow. A turbine with a variable IGV assembly in which vane airfoils extend between inner and outer buttons, an airfoil center of rotation being located aft of an airfoil aerodynamic center of pressure. The airfoil trailing edge (TE) extends into both buttons to eliminate gap between the airfoil TE and a static part of the turbine.
