Preface:

This book is a continuation of my previous two-volume work Large Power Steam Turbines: Design & Operation (PennWell, 1997). Those vol umes were conceived as an exposition of steam-turbomachinery funda mentals as they were seen by the end of the 20th century. This new book to a degree rests on its contents, not repeating previous information as far as possible without sacrifice of comprehension. The afore-mentioned work was also supplemented by another book, Wet-Steam Turbines for Nuclear Power Plants; PennWell, 2005. The present book considers the newest approaches of the latest decade in design, operation, and refur bishment of steam turbines for fossil fuel power plants and is designed to be a final part of this trilogy. At this writing, many people, including some professionals in power engineering, have come to view steam-turbomachinery as a com pletely matured technology that promises no remarkable achievements in the near future. Indeed, by the early 1990s the efficiency of the best new steam turbines had practically stabilized at the previously attained level and did not grow further. Yet, the mid-1990s brought a new break through in the steam turbine technology, and this progress continues today. As a result, new possibilities can considerably raise power plant efficiency based upon qualitative improvements in the turbine steam path design and gradually applying elevated steam parameters. Dr. Wil fried Ulm of Siemens Power Generation qualified this process as “an al most unnoticed revolution in steam turbine technology” [VGB PowerTech 83, no. 1/2 (2003): 1]. These new possibilities can also impact efforts to upgrade old steam turbines in service. New approaches have also been developed and applied to handling the transient operating conditions of steam-turbine-based power units and providing information support for the operational personnel with the use of advanced computerized con trol and instrumentation (C&I) techniques and friendly human-machine interfaces. I marked some of these trends in all these processes in my above mentioned work, written in the mid-1990s, but what once were novelties have brought their first rich fruits in the first years of the new century.
