Turbines, Generators and Associated Plant

The introduction of new 500 MW and 660 MW turbine generator plant in nuclear,
coal- and oil-fired power stations has been partly responsible for the increase
in generating capacity of the CEGB over the last 30 years. This volume provides
a detailed account of experience gained in the development, design, manufacture,
operation and testing of large turbine-generators in the last 20 years. With the advance in analytical and computational techniques, the application of this experience to future design and operation of large turbine-generator plant will be of great value to engineers in the industry.
