COMBINED CYCLE GAS TURBINE (CCGT)

A combined-cycle gas turbine power plant consists of one or more gas turbine generators equipped with heat recovery steam generators working through two different flows, which are able to run in two different thermodynamic cycles. 
This kind of plant is composed by a turbogas unit, a vapour generator and a vapour turbine. The gas, once discharged from the turbogas unit, is sent into the vapour generator where it cools down. The energy released in the vapour generator is utilised to produce vapour that is then used to fuel the vapour turbine. Once the energy gets into the vapour turbine, the turbogas alternator transforms it into electrical energy.
