PROBLEM TO BE SOLVED: To provide a volute type exhaust diffuser in the shape of a volute for a steam turbine. SOLUTION: An axial flow steam turbine includes as an exhaust diffuser a volute (40) for diffusing the exhaust steam and turning the exhaust steam from a generally axial flow direction in a generally radial direction. The volute exit (46) may be at the bottom or to one side of the steam turbine. The volute and casing are independently mounted relative to one another on a foundation with a flexible joint provided therebetween. COPYRIGHT: (C)2007,JPO&INPIT
