ET 851 Steam Turbine Module Show data sheet (pdf file)
Technical Description
The steam turbine together with the steam generator ET 850 forms a steam power plant. The turbine is a single-stage impulse turbine. It expands directly into the condenser. The turbine is loaded using a belt brake dynamometer. The turbine is equipped with safety devices including a steam shut-off triggered by overspeed or excess condenser pressure. All measured values are displayed both on the instruments on the front panel and on a PC via the supplied data acquisition card and software.
