Steam
turbines are turbomachines. In practice, steam turbines are mainly used in
power plants to generate electricity. A distinction is made between turbines
depending on the flow direction and state of the steam, the working process,
and steam supply and discharge. The experimental unit is a single-stage axial
impulse turbine with a vertical axis. The steam required is generated by the
steam generator. The turbine can be operated with saturated steam or
superheated steam. The steam is expanded in the turbine and condensed via the
water-cooled condenser. Load is applied to the turbine via an eddy current
brake. The turbine has a non-contact labyrinth seal on the shaft with a sealing
steam circuit. The turbine is fitted with various safety devices in order to
prevent damage such as by excessively high speed or pressure in the system.
