Abstract
Over the next 20 years the installed generating capacity in the Asia-Pacific region will almost double. Market changes and environmental pressures will necessitate the need for highly-efficient and reliable generating technologies. Besides the construction of new power plants, modernization opportunities of existing steam turbines will be a necessary consideration for plant owners. Siemens Power Generation has considerable experience in the field of steam plant modernization for both fossil and nuclear power plants on our own and other manufacturers fleets. Through the integration of Siemens KWU, Parsons and Westinghouse technologies, and major technology developments, a wide range of modernization solutions can be offered to the power generation industry. This paper provides an overview of the latest proven technologies for steam turbine upgrades. The latest blading technology for high and low pressure turbines is presented. Attention is also given to rotor and casing construction for HP and LP turbines. These modernization technologies are applied to both impulse- and reaction-type steam turbines and examples of successful modernizations to turbines from different manufacturers are shown.
