Abstract (en)
The turbo-machine has a rotatably mounted shaft (10) inside the housing (8,9), where the shaft has a thermally stressed area. A unit (20) is provided for supplying a hot steam to the thermally highly stressed area. The housing has an outer housing that is arranged outside an inner housing. The shaft has a relief groove (15) with a smaller diameter, where the unit is designed such that the hot steam is passed through the relief groove. The shaft is designed as double-flow, where the relief groove is arranged in an inlet area (7) that is formed for supplying the steam. Independent claims are included for the following: (1) a steam turbine plant with a steam generator; and (2) a method for warming a steam turbine shaft.
