Various methods are available for improving the performance of combined-cycle power plants during initial plant design or as uprate oppor-tunities. Improvements can be made in plant output or efficiency beyond those achievable through higher steam temperatures, multiple steam-pressure levels or reheat cycles.

A simple cycle gas turbine can achieve energy conversion efficiencies ranging between 20 and 35 percent. With the higher temperatures achieved in the Department of Energy's turbine program, future hydrogen and syngas fired gas turbine combined cycle plants are likely to achieve efficiencies of 60 percent or more.

Figure shows the flow of working fluids in a gas-steam combined cycle power plant. Piping is coloured to show the different phases in the power plant connection. Temperature and Entropy figures included. Feed …

But this development comes at a time when many of the new combined cycle power plants, and other facilities for that matter, are being staffed by people new to the industry.

The Combined Cycle power plant is a combination of a fuel-fired turbine with a Heat Recovery Steam Generator (HRSG) and a steam powered turbine. These plants are very large, typically rated in the hundreds of mega-watts. They combine the Rankine Cycle (steam turbine) and Brayton Cycle (gas turbine) thermodynamic cycles by using heat …

With engineering and manufacturing of all major components of a combined-cycle power plant inhouse, GE Vernova supplies HRSGs that deliver optimized performance, operating flexibility, and improved reliability for even the most demanding project requirements.

Combined-cycle power plants operate by integrating a combustion turbine generator (CTG) and heat recovery steam generator (HRSG) with a steam turbine generator (STG).

In combined cycle power plants (CCPP) a gas turbine generator generates electricity while the waste heat from the gas turbine is used to produce steam to generate additional electricity via a steam turbine. Siemens has a wide portfolio of cost competitive, high performance, operationally flexible and easily constructable steam turbines to meet ...

Kelanithissa Combined Cycle Power Station. The primary energy options that are being employed in Sri Lanka in the generation of electricity are hydro power, Coal power and fossil fuel based thermal power such as gas turbines, steam turbines, combined cycle plants and diesel engines. The demand for electrical power in Sri Lanka has been …

Other than combustion, pumps are the primary source of energy in the steam cycle. Image 1 illustrates a simple steam generation cycle. Condensate is pumped to a heater, and then the boiler feed pump (BFP) forces the water into the boiler at high pressure, where it transitions to high-pressure steam. The steam then drives a steam …
