A Highly Efficient Steam Turbine-Gas Turbine Cycle

This paper presents the approach used to select a gas turbine steam-turbine cycle of 19,000 kw with the highest efficiency attainable with commercially available equipment at reasonable costs. Mechanical integration of the equipment simplifies operation and contributes to reduced installation costs. The operating characteristics of the resulting plant are dissimilar to conventional steam-turbine plants and on application study is made to determine that significant operating cost gains are attainable when applied to a utility system.
