STEAM TURBINES

Steam Turbines Ansaldo Energia has 100 years’ experience in the design, manufacturing and installation of steam turbines. It has supplied about 700 steam turbines worldwide with a total capacity of nearly 100 GW. Dedicated R&D and Service organizations assist Clients with continuous product improvements, combined with the traditional reliability and robustness of Ansaldo Energia products: the result is a unique and balanced value package based on innovation and reliability. Ansaldo Energia has a comprehensive portfolio of 50 Hz and 60 Hz non-reheat and reheat steam turbines ranging from 40 MW...

Advanced design features Modular design concept Ansaldo Energia steam turbines are based on a modular concept to reduce technical risk and manufacturing time and ensure high reliability. Each model is a combination of well-proven, pre-engineered modules of different sizes, to provide a broad range of power ratings and applications. Several different material options are available to meet different steam conditions up to the most advanced ultra supercritical parameters (600°C/620°C). Steam Turbine IP/LP rotor Blading Over the years of its technological history, Ansaldo Energia has designed both...

Separate HP and IP sections Generally, Ansaldo Energia steam turbines for reheat applications have separate HP IP and LP sec, tions to deliver the highest possible sustained efficiency and good thermal flexibility. For output up to 350 MW, a compact, combined, single flow IP/LP solution is available, thanks also to the use of the welding technique used for the IP/LP rotor. Shrink ring design The HP inner casing of reheat turbines has a shrink ring design that does not require any massive horizontal flange. The shrink rings hold the two half inner casings together to form a symmetrical, light...

Welded rotors Ansaldo Energia uses the welding technique for rotor manufacturing, in which the rotors are built from forged disks and welded together using a combination of tungsten inert gas and submerged arc processes in a dedicated rotor welding shop. This technique allows the use of different materials for HP IP and IP/LP rotors, providing high , temperature resistance at the hot end and high toughness at the cold end, and allowing large LP rotors to be manufactured from smaller forgings. Moreover welded rotors have better thermal flexibility, which is a significant advantage for startup,...

Product Line Steam Turbines for Conventional Steam Cycles Today's medium and large power generation steam turbines are mainly reheat type with regenerative feed water cycle and possible district heating applications. Ansaldo Energia offers three steam turbine models, specifically designed to satisfy all possible Client requirements in terms of operating conditions, performance and reliability, including steam turbines for ultra supercritical applications.

Cogeneration Steam Turbines These turbines, either back pressure or condensing, with or without controlled extractions, are used in industrial, desalination and district heating power plants. As it is basically the process that dictates the steam parameters and therefore the turbine design, each cogeneration steam turbine is a unique product, tailored to the specific needs of the Client. Applications The following references show examples of the aforemetioned product lines.
