ABSTRACT:
An improved multi-stage turbine system is provided which includes a high pressure turbine stage assembly and at least one lower pressure turbine stage assembly. Each of these turbine assemblies preferably has an inlet opening for introducing a thermodynamic medium in the form of a vapor and a discharge opening for discharging the thermodynamic medium from the turbine assembly at a reduced temperature and pressure. Each of the turbine assemblies is typically mounted on a rotatable shaft and these shafts may be coaxially aligned. An assembly such as a clutch may be provided for releasably interlocking the shafts. The thermodynamic medium is transported, when operating conditions are suitable, from the discharge opening of the high pressure turbine assembly to the inlet opening of the lower pressure turbine assembly. When operating conditions are not thus suitable, the thermodynamic medium is transported from the discharge opening of the high pressure turbine assembly to an apparatus for vapor liquification such as a condenser.
