Several cycle configurations are possible with respect to water/steam injection. Figure 4.36 is the schematic diagram of the Steam-injection gas turbine cycle.

The Austrian, Gzechoslovakian, Danish, Dutch, Finnish, Hungarian, Norwegian, Polish, and Swedish classifications are based on the German. Generally, the main classes are identical, but ithe subdivision of the classes is not so extensive.
