Combined-cycle Power Plants. Combined-cycle technology uses both a gas turbine and a steam turbine to generate electricity burning natural gas, a fuel with a lower environmental impact than other fossil fuels. The exhaust heat from the gas turbine is used to generate steam, generating electricity twice and minimizing waste. High thermal

Upon commissioning, the 225MW project will be one of the biggest gas-fired power plants in the country. The power plant will be built on a greenfield site
Learn how gas turbines and combined cycle power plants (CCPP) work. This video explains how gas turbines efficiently convert air and fuel into mechanical ene
More than 60 years of experience. We''ve been designing combined-cycle power plants since 1949, longer than any other OEM. Gas turbines have evolved from relatively small, simple peaking machines to much larger combined-cycle plants capable of powering a city. GE draws on this rich technology heritage and continues to innovate, developing
As you can see from the GE case, the efficiency of combined cycle power plant has already surpassed the 60% mark. This is how the industry calculates this efficiency: h cc = h c1 + h c2 – h c1 h c2 Where; h cc = Combined Efficiency. h c1 = Efficiency of Cycle 1. h c2 = Efficiency of Cycle 2. Assuming the first cycle efficiency is 40% and the

In this paper, a combined solid oxide fuel cell (SOFC) and gas turbine fuelled by natural gas is proposed as an attractive option to limit the environmental impact of the marine sector. It includes a study of a heat-recovery system for 18 MW SOFC fuelled by natural gas, to provide the electric power demand onboard commercial vessels.
The cost and performance characteristics of these plants are adapted from EIA data rather than derived from original analysis. Natural gas plant CAPEX is taken from the AEO2019 (EIA, 2019a) with the adjustments
This is the first study that combine model validation of the gas-fired power plant with process synthesis of three combined configurations to identify the cost-optimal one. The optimal operating parameters and design variables within these configurations such as split ratio, stream withdrawal and return location are selected based on
Gas-fired power plants can be modified to run on hydrogen, and according to General Electric a more economically viable option than CCS would be to use more and more hydrogen in the gas turbine fuel. Hydrogen can at first be created from natural gas through steam reforming, or by heating to precipitate carbon, as a step towards a hydrogen
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
A combined-cycle gas turbine (CCGT) power plant uses the exhaust heat from gas turbines to generate steam with a heat recovery steam generator (HRSG). The produced steam is then fed to a steam turbine to provide additional power, either running a generator or as a mechanical drive. The overall efficiency of an offshore CCGT is approximately 50%.
Gas turbine combined cycle （GTCC） power plants use natural gas to deliver the cleanest and highest efficiency power generation.
