PRODUCT DESCRIPTION Competitive pressures are driving power generators to exploit aviation combustion turbine technology to create more efficient and powerful generation plants at lower cost. However, the use of aero-derivative combustion turbines (third generation or «next generation») carry a degree of technical risk because technologies incorporated into their design push them to the edge of the envelope. This report reviews the design evolution and experience base of advanced Rolls-

introductions as design changes go from the ‘drawing boards’ into production testing at a customer’s site early in the learning curve. The absence of long-term experience with the technology raises issues of reliability and durability. For specific models and components, chronic durability problems could result in insurability issues potentially undermining a project’s financial structure. Applications, Values & Use This report, along with EPRI’s previously published design evaluatio

EPRI Proprietary Licensed Material 1 INTRODUCTION The power generation market place and the combustion turbine market in particular are evolving at an ever-increasing pace. Market forces are driving the introduction of new technologies and advanced combustion turbines designs. The introduction of these technologies inherently involves risk. The economic pressure of a market moving towards deregulation intensifies this risk of new technologies. Whereas in the past new products were
