Turbo set with starting device

Abstract

In a turbo set (100) with a starting device (120), the turbo set includes a compressor (102), a combustion chamber (103) and a turbine (104) and also a generator motor (108) which is drive-connected to the turbine (104). The starting device (120) serves for starting the turbo set and includes a steam generator (121) for the generation of steam which is under overpressure, a steam turbine (129) and an auxiliary generator (130). The steam generator (121) and the steam turbine (129) are connected to one another via a first supply line (125a) for the supply of steam generated in the steam generator (121) to the steam turbine (129). The auxiliary generator (130), on the one hand, is drive-connected to the steam turbine (129) and, on the other hand, for the transmission of electrical power from the auxiliary generator (130) to the generator motor (108), is electrically connected to the generator motor (108). In a method for starting the turbo set, the method includes generating steam which is under overpressure, at least partially expanding the steam so as to generate electrical power, and starting the turbo set electromotively with the electrical power.
