What is 7HA gas turbine?
The 7HA suite of gas turbines’ flexibility enables increased dispatch and ancillary revenue, while enhanced fuel flexibility accommodates a wide range of gaseous fuels (shale gas, high ethane, H2) and liquid fuels (#2 diesel, crude oils).
What is a 2×1 combined cycle?
2×1 configuration of combined cycle plants In this configuration, the plant has two gas turbines of the same capacity, each connected to its own generator, and the gas is fed to two independent heat recovery steam generators (HRSG). However, this configuration has some disadvantages.
How does the combined-cycle work?
A combined-cycle power system typically uses a gas turbine to drive an electrical generator, and recovers waste heat from the turbine exhaust to generate steam. The steam from waste heat is run through a steam turbine to provide supplemental electricity.
How does a combined-cycle gas plant work?
A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50% more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power.
How much does a GE turbine cost?
With regard to power generation installed costs, GE’s new turbines are within the $500 to $700 per kilowatt range, said DeLeonardo, while renewables are around $1,500 per kilowatt and nuclear can be $5,000 per kilowatt.
What are aeroderivative gas turbines used for?
In the mid-1980s independent power producers began using aeroderivative gas turbines for combined heat and power genera- tion, also called cogeneration. In this configuration, the exhaust heat of the gas turbine is used to produce steam to directly heat a building or industrial process.
What is aeroderivative power?
One area of widespread use of aeroderivative gas turbine technology is in aviation where the power harnessed by the turbine is used to power a compressor. The hot air that exits the turbine is used for thrust by forcing the air into the atmosphere via an exhaust nozzle.
