Abstract

PURPOSE: To enable turbulence flow from stationary blades to exhaust from main flow and reduce moving blade secondary flow loss by providing the clearance spaces between stationary blades and moving blades with flow-dividing ring plates formed to project toward the main flow.
CONSTITUTION: A turbine stage consists of stationary blades 16 and moving blades 17, outer and inner diaphragms 18 and 19 holding firmly the stationary blades 16, a disk 20 holding firmly the moving blades 17, shround rings 21 connecting circularly every several number of moving blades 17, 35c. In this case, the clearance spaces 22 and 22', between the stationary and moving blades in the turbine axial direction at the blade root and tip portions, are provided with flow-dividing ring plate 23 and 23' formed to project toward main flow. Hereby, turbulence flow 24 and 24', devloped within the stationary blades 16, are exhausted such as flow lines 26 and 26' from the main flow through passages 25 and 25' consisting of the flow-dividing plates 23 and 23', projected into δ portions of the turbulence area, and the diaphragm walls.
