Operating Experiences in Connection With Regenerative Reheat-Turbine Installations

This paper relates to the performance and design of regenerative reheat steam turbines, particularly several large 1800-rpm tandem-compound generating units. The author, who has been associated with field work and design of both these and marine types, discusses installations in the stations of two power companies. A description of these units, together with their respective reheat systems and protective equipment, is given, and many details of design and operation are discussed. The paper covers experiences for a period of 18 years, and also considerations relating to units now being installed or under construction.
