A steam generator generates steam which will later be used in drives for steam turbines or for heating. Steam generators and steam consumers together form a steam power plant. Steam power plants work according to the Rankine cycle which is still one of the most important industrially used cyclic processes. Steam power plants are mainly used for electrical power generation.
The steam generator and the axial steam turbine together form a complete laboratory-scale steam power plant. The trainer serves to familiarise students with the components and principle of operation of a steam generator and enables them to examine the characteristic values of the system. If the steam generator is operated without the steam turbine, the generated steam is directly liquefied in a condenser and fed back into the evaporation circuit via condensate and feed water pump.
