16 54,093 Abstract of the Disclosure A turbine having structure for reducing thermal deformation caused by thermally created loads directed parallel to the axis of rotation of the rotor, which structure includes a stator assembly, positioned within a casing and about said rotor, wherein the casing has an inlet defined by sidewalls, the stator assembly having an inlet for directing a flow of steam, wherein the inlet is defined by first blade rings connected to the casing sidewalls and having a stationary annular row of blades connected to each of the blade rings and operatively positioned in relation to the rotor blades for directing a flow of steam onto the rotor blades and having a number of ribs disposed within said stator assembly about said rotor, wherein the ends of said ribs are spaced away from the sidewalls and the first blade rings. The sidewalls of the casing can also be disposed substantially perpendicular to the axis of rotation so that thermally created loads caused by heat transferred from said flow of steam to the sidewalls are directed primarily perpendicular to the axis of rotation.
