This patent describes a double flow steam turbine. It comprises rotor with annular rows of blades disposed about its periphery, a stator assembly connected about the rotor and having annular rows of stationary blades affixed thereto, the stator assembly including a steam inlet for directing a flow of steam onto at least a pair of first stage stationary blade rows in a desired steam flow path, each of the first stage stationary blade rows being positioned on opposite sides of the steam inlet and located for directing the flow of steam onto corresponding rows of rotor blades, at least the first stationary blade rows having an inner blade ring, apparatus for improving the efficiency of the steam turbine by reduction of steam bypassing the first stage blade rows via leakage around the inner blade rings including sealing means coupled between the inner blade rings of the first stage stationary blade rows.
