FIELD: mechanical engineering; turbines. SUBSTANCE: turbine stage guide blade has leading and trailing edges, surface with convex and concave sides, step located along blade height at convex side of surface and pointed towards trailing edge. Step is made in upper half of blade height at a distance from leading edge equal to 30-80% of blade width. EFFECT: improved reliability of operation of wet-steam stage by intensification of breaking and acceleration of moisture large-size dispersed particles before working blade. 4 dwg
