Steam infeed for a steam turbine
The steam supply unit (11) has an outer pipeline (14) arranged around an inner pipeline (12), where a coolant inlet opening (17) is provided for supplying a coolant i.e. live stream, between the inner pipeline and the outer pipeline. Two components (23, 24) exhibit respective inner pipelines (26, 28) and respective outer pipelines (27, 29), where the outer pipeline (14) is formed from the outer pipelines (27, 29) and the inner pipeline (12) is formed from the inner pipelines (26, 28). The inner pipeline (12) and the outer pipeline (14) are formed in a material single-piece manner.
