Those volumes were conceived as an exposition of steam-turbomachinery fundamentals as they were seen by the end of the 20th century. This new book (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich) 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 (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich), Wet-Steam Turbines for Nuclear Power Plants; PennWell, 2005.
The present book (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich) considers the newest approaches of the latest decade in design, operation, and refurbishment 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 completely 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 breakthrough 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. Wilfried Ulm of Siemens Power Generation qualified this process as “an almost 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 control 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.
Valuable descriptions of new achievements in steam-turbomachinery and their effects were published by their developers in the late 1990s and early 2000s, but these separate publications have never been gathered together and generalized, to the best of my understanding.
Among modern books on steam-turbomachinery which appeared after the afore-mentioned Large Power Steam Turbines: Design & Operation, two noteworthy books were issued just at the turn of the century and addressed primarily to power plant maintenance staff:
Turbine Steam Path Damage: Theory & Practice by T.H. McCloskey, R.B. Dooley, and W.P. McNaughton (EPRI, 1999) and Turbine Steam Path: Maintenance & Repair by W.P. Sanders (PennWell, 2001). These works summarized the current knowledge about damages in the turbine steam path and methods for revealing and repairing them.
A general overview of turbomachinery for the power industry at the end of the 20th century is offered in H. Termuehlen, 100 Years of Power Plant Development:
Focus on Steam and Gas Turbines as Prime Movers (ASME, 2001). The present book (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich), as well as my previous ones, differs from those mentioned above in that it is addressed mainly to power plant operators and operation researchers and was written from their point of view.
The book (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich) does not try to tell the readers how steam turbines should be designed but rather explains why they were designed as they were and compares different possible design solutions.
It absorbs the experience in steam-turbine design and operation accumulated in developed and developing countries throughout the world—in the USA, Germany, Japan, Russia, Denmark, Korea, and India, among others.
This book (Steam Turbines for Modern Fossil Fuel Power Plants by Alexander S. Leyzerovich) is a continuation of my previous two-volume work Large Power Steam Turbines: Design & Operation (PennWell, 1997).
