While the efficiency increase is welcomed, Alstom’s focus during its steam turbine upgrades is not simply on ramping up the turbine; but rather optimizing the entire shaft line and accessory ...

The plant’s owner, Gemeinschaftskraftwerke Irsching GmbH—a joint venture of E.ON, Mainova, and HEAG Südhessische Energie—features two SGT5-4000F gas turbines, one SST5-5000 steam turbine ...

A new extra-long turbine blade launched by Alstom promises improved efficiency and performance for its future nuclear power plant steam turbines. A new extra-long turbine blade launched by Alstom ...

The most critical aspect of steam turbine efficiency and reliability is the steam path design. Stationary nozzles, diaphragms and rotating blades (or buckets) comprise the steam path. The blades ...

Gas turbine makers GE, Siemens, and Mitsubishi Heavy Industries (MHI) in the last week of May separately profiled unprecedented results from development or testing of three innovative combined ...

The paper considers a method for the evaluation of the power plant steam turbines operating modes efficiency. The efficiency is evaluated by comparing the specific heat rate for power generation in ...

For example, on a unit that has operated more 30 years, GE’s steam turbine efficiency upgrade can recover 10 percent degradation and increase performance 5 percent beyond its original level. In ...
