FIELD: heat power engineering. SUBSTANCE: ring converging-diverging passageway connects the flowing part of the turbine with the take-off chamber. The average ellipticity of the diverging part is equal to or greater than 1.15 but no less than 1.25, the divergence angle being equal to 2-7°. The ratio of the minimum to maximum cross-section is equal to 0.03-0.35. The outlet diameter of the diffuser has an eccentricity with respect to the inlet diameter. The ratio of the eccentricities is 0.04-0.075. The minimum inlet diameter of the diffuser is located from the side of the take-off branch pipes. EFFECT: improved design. 2 dwg
