Abstract:
A method for operating a multi-step steam turbine operating in high temperature conditions is provided. The rotor is embodied as a welded construction including a first component and a second component. A coolant is supplied to the steam turbine after an intermediate state when the steam turbine is in the light-load or no-load phase. As a result, the thermal loads in the outflow area of the steam turbine are reduced.
