2011-5-10 · Combined Cycle Power Plant: A combined cycle gas turbine power plant is essentially an electrical power plant in which a gas turbine and a steam turbine are used in combination to achieve greater efficiency than would be possible independently. The gas turbine drives an electrical
The most common type of combined cycle power plant utilizes gas turbines and is called a combined cycle gas turbine (CCGT) plant. Because gas turbines have low efficiency in simple cycle operation, the output produced by the steam turbine accounts for about half of the CCGT plant output.
Light liquid and gas fuels can also use a gas turbine cycle or a combined gas turbine/steam turbine cycle, but these fuels are also commonly used in single cycle steam turbine setups. Therefore, the single cycle steam turbine power plant is the most common fossil fuel power plant …
