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.

Method for operating a multi-step steam turbine

The invention relates to a method for increasing the steam mass flow of a high-pressure steam turbine of a steam power plant, particularly a steam power plant including reheating, during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, wherein at least one electric consumer is connected upstream of a generator of the steam power plant before synchronization with a power supply grid. The invention further relates to a steam power plant, comprising a generator, a high-pressure steam turbine, and at least one electric consumer, which can also be connected during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, in order to increase a steam mass flow of the high-pressure steam turbine before a synchronization process of the generator with a power supply grid.

Turbine blade

A steam power plant arrangement with a steam turbine and a steam generator, a condenser and a preheating system is characterized according to the invention in that the steam generator, the condenser and the preheating system are configured as individual functionally and spatially defined function areas, which are arranged in a spatial installation concept in a distributed manner around the steam turbine.
