STEAM POWER INSTALLATION HAVING A STEAM GENERATOR THAT COMPRISES A DRUM-PRESSURE-MAINTAINING FITTING

摘要

The invention relates to a steam power installation (1) comprising a steam turbine (3) and a steam generator (2), a drum being formed in said steam generator (2) together with a drum-pressure-maintaining fitting (20) that is designed to govern the pressure. In addition to the governing function, the drum-pressure-maintaining fitting (20) also takes over a rapid shut-off function in the event of a malfunction and for example receives a signal during an overspeed, thus permitting the supply of steam to be rapidly shut off.
