The highly dynamic nature of power demand forces a combined cycle gas turbine (CCGT) power plant to often run at less-efficient part-load conditions. A new operating strategy called EGR-IGVC is proposed in this work to improve the part-load performance of a CCGT plant. The strategy partially recycles the flue gas from the heat

The syngas is burned adiabatically (and completely), and the products exit at 1600 K. The pressure drop within the combustor is 5%. The combustion products expand in the turbine whose isentropic efficiency is 90%. The turbine exhaust is cooled to 30 °C to condense water. Some of the CO2 is recycled.
Combined cycle gas turbine (CCGT) power plants that use natural gas as the fuel are among the most efficient with a thermal efficiency as high as 60% (Rao, 2012). As a result, CCGT plants are now undergoing widespread installations.
Abstract. Combined cycle gas turbine (CCGT) power plants are becoming increasingly important for electricity generation. Enhancing their thermal performance is essential for mitigating carbon emissions. This paper aims to present a methodology for simulating the off-design operation of a triple-pressure reheat CCGT
This paper describes the effects of degradation of the main gas path components of the gas turbine topping cycle on the combined cycle gas turbine (CCGT) plant performance. First, the component degradation effects on the gas turbine performance as an independent unit are examined. It is then shown how this degradation
In general, the Brayton cycle describes the workings of a constant-pressure heat engine. It is the one of most common thermodynamic cycles that can be found in gas turbine power plants or in airplanes. In contrast to Carnot cycle, the Brayton cycle does not execute isothermal processes, because these must be performed very

The Combined Cycle Power Plant or combined cycle gas turbine, a gas turbine generator generates electricity and waste heat is used to make steam to generate additional electricity via a steam turbine. The gas turbine is one of the most efficient one for the conversion of gas fuels to mechanical power or electricity.
Among the advantages of a combined cycle plant, the following stand out: High energy efficiency: By using two different thermodynamic cycles, these power plants can harness more than 60% of the energy from the natural gas that is burned, compared to 30-40% that is used in a conventional thermal power plant. Lower emission of polluting
