Abstract
A turbine casing for an axial-throughflow gas turbine surrounds at least one hot-gas space between a compressor stage and a turbine stage and has an outer shell as an external boundary and also an inner shell which is provided separately from the outer shell and which separates the hot-gas space from the outer shell via an annular space. The inner shell is connected to the outer shell via two axial interfaces, in such a way that the annular space is sealed off relative to the hot-gas space. The turbine casing withstands higher compressor final pressures and temperatures and can be produced cost-effectively.
