"Present state-of-the-art in gas turbine combined cycle (GTCC) design is three-pressure, reheat (3P-RHT) steam bottoming cycle with steam generation at three different pressure levels. The goal is to maximize total steam generation and steam turbine generator power output for a given gas turbine exhaust energy and, thus, to maximize combined cycle efficiency."

"A steam turbine is designed and optimized for a specific set of steam conditions. After long term operations either the steam path components deteriorate or due to changes in steam conditions, a re-optimization of the steam path components is required to regain higher turbine performance. Steam Turbine retrofits are performed to achieve various goals such as improved turbine efficiencies, heat rate or power output. Retrofits are also performed to address turbine reliability and or maintenance issues. Availability of newer technologies and materials for steam path components can be utilized to not only increase steam turbine performance, but also to extend maintenance intervals, and extend life. Retrofits can also accommodate required changes to the thermal cycle based on emerging needs of the power plant. The effectiveness of the retrofit is achieved by ut ...

"There is a quiet (and sometimes not so quiet) revolution taking place in the way America powers its motors, engines, and turbines. Industrial motors, traditionally powered by diesel and gasoline fuels, are transitioning to a new fuel source—natural gas."

"... Now, with demands for energy rising along with calls for reduced greenhouse gas emissions, the need for cleaner more efficient next generation turbine technology is critical. With a robust research portfolio, productive partnerships, and a mandate to increase power-producing efficiencies and improve the environment for future generations, the National Energy Technology Laboratory (NETL) is shepherding innovations for improved gas turbine productivity."

"Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase."

"Highly flexible, fast-ramping, fast-cycling combined cycle plants hit the market with a big splash a few years ago. But are they performing as advertised? Though the few operational plants are still new and still learning, the initial results are encouraging."
