and steam turbine. The constant increase of the turbine inlet temperature of the gas turbine led to exhaust temperatures far above 600°C and enabled the application of a 600°C water/steam cycle. Figure 2.2 shows the constant improvement of combined cycle efficiencies starting from 52% efficiency with low steam parameters in 1991.
