Abstract : In turbines operating at a variable rotational speed large variations in operating conditions are connected with large losses in energy. The losses in ordinary adjusting stages substantially affect the overall efficiency of the turbine irrespective of the partial recovery of heat in the subsequent stages. The present article describes the results of the theoretical and experimental investigation of double-rim control stages with the second rim by-passed at higher loads. The material refers to turbines in which the characteristic number of the adjusting stage varies within a wide range depending on the operating conditions. Graphs cover the internal efficiencies, relative heat drop across the by-pass, the relative magnitudes of the kinetic energy, and the peripheral efficiency.
