Abstract

PURPOSE: To reduce pressure loss by providing a partition unit in a gap between stages of a turbine for regulating the operating fluid in the gap axially and dividing its axial flow into several passage.
CONSTITUTION: Around the steam entrance of a steam turbine, turbine blades 13, 16, and 18 in the first, the second, and the third stage are provided to receive steams injected from the first, the second, and the third stage nozzle 12, 15, and 17 given inside a casing 40 for giving a rotary power to a rotor 19, while a stage gap 14 is provided between the first and the second nozzle 12 and 15. Here, in the stage gap 14 between the first and the second stage, a partition unit 50 composed of an arc-shaped outside and the same outside part 22 and 24 with L-shaped section to regulate the steam flow axially and two side partition parts 25 and 26 firm fixed between both ends of above partition parts to regulate the steam flow axially, is provided for attaining the expected purpose.
