The cogeneration steam turbine of the T-63/76-8.8 type for a series of PGU-300 combined cycle power plants

Abstract

This paper describes in detail the design of the T-63/76-8.8 steam turbine manufactured by Ural Turbine Works (refurbished significantly), its electrohydraulic control and protection system made according to the current requirements on control and protection, the heat flow diagram, and arrangement of the tur- bine. The T-63/76-8.8 steam turbine is intended to be used in double-shaft double-circuit combined-cycle monoblocks at a number of thermal power plants currently under construction. The turbine has a great future, since it may be employed in various combinations with gas turbine units having the output of 150-170 MW that are manufactured by virtually all firms. © Pleiades Publishing, Inc., 2012.
