Advanced aerothermodynamics associated with clean technologies for upgrading gas turbines in simple and combined-cycle power stations

摘要

For improving simple old ['peak-power'] and newer combined-cycle gas turbines [CCGT] hot sections, and for increasing their service life, an EC-Thermie-funded Gas Turbine Consortium [GTC] has recently been established by the author with three EU industrial partners. Using three military-developed aero-engine-derived methods developed by the author, the GTC's major aim is to increase gas-turbine hot-section life-span while using clean technologies. The EC-Thermie/GTC demonstration is currently being conducted with a world-unique, inter-cooled/ inter-heated/recuperated gas turbine characterized by super-efficiency potentials which may surpass 50% without using a CCGT per se. It is currently being cell-tested by Schelde-Heron[SH] of the Royal Schelde Group in Holland. The unique design philosophy of SR and of this EC-Thermie/GTC Project combines advanced military combustor methods with an advanced basic thermodynamic cycle characterized by low-pressure/low-temperature operating conditions. This new basic design approach helps maximizing engine efficiency and service life while minimizing purchasing and operating costs and emissions.
