- Compounding of steam turbines is the method 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 i.e. it has more than one set of nozzles and rotors, in series, keyed to the shaft or fixed to the casing, so that either the steam pressure or the jet velocity is absorbed by the turbine in number of stages.
- Compounding of steam turbines are done, where rotor speed (flow speed) is reduced in steps, this prevent over speeding of turbine, which could lead to mechanical failures of turbine blades.
