The 125 MW Combined Cycle Power Plant “Korneuburg-B”: Design Features, Plant Performance and Operating Experience

Abstract

In January 1980 NEWAG, an Austrian utility, commissioned a natural gas fired 125 MW combined cycle unit at Korneuburg near Vienna. The plant has some interesting characteristics which have led to an exceptionally high net efficiency during the first 19 months of operation though the plant is started twice daily within 30 minutes and is used for medium/peak load shaving. A detailed description of the fully automized plant systems, their main components, the design and test data, as well as the operational experience are given in this paper. The Korneuburg plant can be considered as an example of the present state of the art of power plant engineering.
