Abstract

A multi-stage axial flow steam turbine having an inner and outer casing, the inner casing being a pressure vessel one end of which is open to the outer casing and the other end being closed by segmented nozzle chambers which are disposed around a rotor. A control stage and a plurality of reaction stages are disposed within the inner casing. The outer casing has a plurality of stages disposed therein so that steam leaving the inner casing flows over the outer peripheral surface of the inner casing and over the nozzle chambers, cooling them before entering the stages disposed in the outer casing. The inner casing is mounted within the outer casing in such a manner as to limit relative axial movement and allow free relative radial movement between the inner and outer casing, which is caused by changes in temperature. A steam pressure sealing device is provided between the nozzle chambers and the inner casing, the sealing device being adapted to allow free thermal expansion of the nozzle chamber with respect to the inner casing.
