Steam turbines are turbo machines. Inpractice, steam turbines are mainly used in power plants to generateelectricity. A distinction is made between turbines depending on the flowdirection 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 verticalaxis. The steam required is generated by the steam generator. The turbine canbe operated with saturated steam or superheated steam. The steam is expanded inthe turbine and condensed via the water-cooled condenser. Load is applied tothe turbine via an eddy current brake. The turbine has a non-contact labyrinthseal on the shaft with a sealing steam circuit. The turbine is fitted withvarious safety devices in order to prevent damage such as by excessively highspeed or pressure in the system. Sensors record the temperature, pressure, andflow rate at all relevant points. Turbine speed and torque are measuredelectronically at the eddy current brake. The measured values can be read ondigital displays. At the same time, the measured values can also be transmitteddirectly to a PC via USB. The data acquisition software is included. The axial steam turbine, together with the steam generator, forms a completelaboratory-scale steam power plant.
