Riedler-stumpf turbine Terry turbine. Sturtevant turbine. WebCompounding of steam turbines is the strategy in which energy from the steam is extracted in a number of stages rather than a single stage in a turbine. A compounded steam turbine has multiple stages e.g it has more than one set of nozzles and rotors. These are arranged in series either keyed to the common shaft or fixed to the casing.
