A Conceptual Design for a Combined Cycle Power Plant Comprising Modified Exhaust-Heated Gas Turbine and a Steam Turbine Plant: Part I — Preliminary Calculations, Basic Dimensions and General Design Conception

Abstract

An example of the application of a modified exhaust -heated gas turbine system (with fourfold compression and fourfold expansion) coupled with a steam turbine plant with reheat has been presented. Schematic arrangement and design data of a combined plant have been shown (state parameters of fluids, mass-flow rates, dimensions, etc.). Natural gas has been taken into consideration as fuel. In spite of comparatively high pressure losses on the gas side a thermal efficiency of 50% on clutch (about 47,5% on terminals) is obtainable.
